Petra: the Rose-Red City Carved from Stone

There is no entrance to an ancient city anywhere on earth quite like the entrance to Petra. The traveler comes from the dusty desert plateau of southern Jordan, passing through the modern visitor center and then descending into a dry riverbed valley that narrows imperceptibly, the canyon walls rising on either side, the path threading between boulders and smooth stone faces until, at some uncertain point, the passage becomes the Siq — one of the most theatrical approaches to any archaeological site in the world. For 1.2 kilometers, the traveler walks through this narrow gorge, the walls rising to 80 meters on either side, the sky reduced to a ribbon of blue overhead, the sandstone all around shifting through extraordinary gradations of color: red, amber, purple, lavender, cream, ochre. The passage twists and turns, offering nothing to prepare the mind for what is coming. And then, at the end of the last bend, the Siq opens out and the Al-Khazneh appears in the cliff face directly ahead — a facade of breathtaking scale and refinement, approximately 40 meters tall and 28 meters wide, carved entirely from rose-red sandstone, its columns and pediments and carved figures standing in pristine exactitude after two thousand years. The effect is one of the most startling in all of human experience: astonishment, incomprehension, and the overwhelming presence of a civilization so accomplished in its grasp of beauty that it chose to make its greatest monuments not by building upward into the sky but by cutting them directly into the living rock of a desert canyon.

This is Petra, the ancient capital of the Nabataean kingdom, located in the Arabah valley of what is now the Hashemite Kingdom of Jordan, approximately 240 kilometers south of the capital Amman. It is a UNESCO World Heritage Site, inscribed in 1985, and in 2007, in a worldwide vote organized by a Swiss foundation, it was named one of the New Seven Wonders of the World. The British poet John William Burgon, who won the Newdigate Prize at Oxford in 1845 with a poem about Petra, gave it the description that has followed it ever since: "a rose-red city half as old as Time." The description is poetically imprecise — Petra is not a single rose-red color but a thousand variations — but it captured something essential about the place, and the phrase has clung to it for nearly two centuries.

The Nabataeans: Masters of the Desert

Before there was the spectacular architecture, before the carved facades and the cut stone channels and the elaborate tombs, there was the Nabataean people — one of the most remarkable civilizations of the ancient world, and one of the least well understood. The Nabataeans appear in ancient sources as a nomadic Arab people living in the region of the Negev, the Sinai, and the northwestern Arabian Peninsula. The earliest historical references to them come from the late fourth century BCE, when accounts from the period of the successors of Alexander the Great describe them as a fiercely independent desert people who had resisted conquest by mounting a vigorous defense of their rocky plateau stronghold. They were, initially, a nomadic people whose wealth came from controlling the movement of goods across the vast desert spaces of the ancient Near East.

Over the following two centuries, the Nabataeans underwent a profound transformation: from nomadic traders to settled urbanists, from desert wanderers to architects and engineers of extraordinary sophistication. The mechanism of this transformation was commerce. The ancient world ran on commodities that could only be obtained from specific and distant sources: frankincense and myrrh came from the southern Arabian Peninsula, specifically from the Dhofar region of modern Oman and from parts of what is now Yemen; spices came from India; silk came from China; precious metals came from Africa and from the mines of the ancient world. All of these goods needed to move overland to reach the markets of the Mediterranean world, the great cities of Egypt, the Levant, and Greece. The routes they traveled passed through the territory the Nabataeans controlled, and the Nabataeans had the organizational capacity, the knowledge of the desert, and the military force to make themselves indispensable to these trade flows.

At the height of their power, between approximately the second century BCE and the first century CE, the Nabataeans controlled what amounted to a commercial empire that stretched from the Hejaz in the south to Syria in the north, from the Sinai in the west to the Gulf of Aqaba in the east. Petra sat at the heart of this network, a city of between 20,000 and 30,000 inhabitants at its peak — an extraordinary figure for a location in the middle of one of the harshest deserts on earth. The wealth that flowed through Petra was immense. Caravan trains carrying frankincense and myrrh, bales of spices, bales of silk, precious stones, copper, and ivory arrived and departed constantly. Petra was a city of merchants, financiers, caravan masters, and craftsmen, and its prosperity expressed itself in the extraordinary built environment that the Nabataeans created.

What made the Nabataean achievement at Petra so remarkable was not merely the scale of their architecture but the conditions under which they built it. The Arabah valley receives very little rainfall — perhaps 50 to 100 millimeters annually, most of it falling in brief, violent winter storms. For a city of tens of thousands of people to survive in such an environment required an engineering solution of exceptional ingenuity, and the Nabataeans provided one. They cut channels, pipes, and cisterns directly into the sandstone throughout the city and its surrounding landscape, capturing every drop of rainwater and every trickle from distant springs and conducting it through a network of gravity-fed channels to reservoirs and distribution points within the city. The system included sealed clay pipes, settling tanks to filter sediment, and an elaborate hierarchy of collection and storage that allowed the city to maintain water supplies even during extended droughts. This hydraulic genius was perhaps the Nabataeans' greatest single achievement — it made life in Petra not merely possible but prosperous, and it is one of the most impressive examples of ancient water engineering anywhere in the world.

The Siq and the Approach to Petra

The Siq, the extraordinary natural gorge that serves as the main entrance to Petra, was not merely a practical route into the city. It was also a sacred and symbolic passage, and the Nabataeans enhanced its numinous character with deliberate interventions. Along the walls of the Siq, the Nabataeans carved niches containing religious images — small rectangular carvings representing the god Dushara, the principal Nabataean deity, whose form was often an uncarved block of stone or a simple obelisk. They also carved inscriptions and the names of wealthy citizens who donated to the upkeep of the approach. Water channels were cut into both walls of the Siq at a height of approximately one to two meters, running the entire length of the gorge — one bringing water from the spring of Ain Musa (the Spring of Moses) into the city, and the other serving as a drainage channel for floodwaters that might otherwise fill the gorge catastrophically during winter storms.

The walls of the Siq display the extraordinary geological history of the Petra region in cross-section: the sandstone through which the gorge cuts was laid down in geological epochs long before the appearance of humanity, and over millions of years the mineral content of the sediment — iron oxides, manganese oxides, silica, calcium carbonate — has colored successive strata in bands of red, white, purple, yellow, and black. The tectonic forces that uplifted the region and fractured the rock created the original gap that erosion and flash floods then widened into the Siq. The result is a geological artwork of extraordinary beauty that the Nabataeans incorporated into their city rather than obscuring it.

At several points along the Siq, the walls narrow to only a few meters apart. Camel caravans must have passed through here, and the great commercial processions that characterized Petra's peak would have been funneled through this narrow passage before emerging into the city's central precinct. The drama of this constriction followed by the revelation of the Treasury is not accidental: it is a theatrical effect that the Nabataeans almost certainly understood and cultivated, making the approach to their capital a journey that built anticipation before releasing it in a moment of overwhelming visual impact.

The Al-Khazneh: the Treasury

The Al-Khazneh, known in the West as the Treasury, is the most famous and the most visited monument in Petra, and it represents Nabataean architecture at its most refined and imposing. The facade is carved from a single cliff face of rose-red sandstone, cut to a height of approximately 40 meters and a width of approximately 28 meters. The name "The Treasury" derives not from any ancient source but from a legend current among the Bedouin of the region in the nineteenth century, who believed that an ancient pharaoh had hidden his treasure in the large stone urn carved at the top of the facade's second register. So persistent was this belief that local tribesmen periodically fired rifles at the urn in hopes of shattering it and releasing the gold — which explains the numerous bullet pockmarks still visible on the urn today.

In fact, the Al-Khazneh was in all probability a royal tomb and funerary monument, constructed in the late first century BCE or the early first century CE. The identity of the king for whom it was built has been debated by scholars, with both Aretas III and Aretas IV proposed as the most likely candidates. Aretas IV, who ruled from 9 BCE to 40 CE, was the most powerful of all Nabataean kings, the man who extended the kingdom to its greatest territorial extent and presided over Petra's golden age, and he is mentioned by name in the New Testament: in his second letter to the Corinthians (2 Corinthians 11:32), the apostle Paul mentions the "governor under Aretas the king" in Damascus from whom he was forced to flee. Under Aretas IV, Petra developed a chain of settlements along the caravan routes, established merchant outposts as far away as Alexandria in Egypt and Pozzuoli in Italy, and controlled the Silk Road, the Frankincense Road, and the King's Highway simultaneously.

The architectural vocabulary of the Al-Khazneh is a sophisticated blend of Hellenistic and Nabataean elements. The lower register presents a classical Hellenistic facade, with six Corinthian columns supporting a richly decorated entablature and pediment. The upper register is more complex and less orthodox: a central tholos (circular temple) is flanked by two broken pediments, the spaces between them filled with carved reliefs of eagles, griffins, and the Nabataean goddess al-Uzza, identified with the Greek Tyche and the Egyptian Isis. The entire composition is carved from the living rock with extraordinary precision, the depth of the relief carving creating strong contrasts of light and shadow throughout the day. In the early morning light, when the sun hits the facade directly, the sandstone glows a deep rose-red. At midday, the upper sections fall into deep shadow while the lower columns stand in full light. At sunset, the colors shift toward orange and amber, and the carved surfaces take on a quality of warmth that seems almost internal, as if the stone were generating its own illumination.

The interior of the Al-Khazneh is relatively simple: a main chamber approximately 12 meters square, with smaller side chambers, carved from the rock with smooth walls and a flat ceiling. There are no original inscriptions or paintings surviving inside that would definitively identify whose tomb it was. The funerary function is inferred from the architectural typology and from the position of the monument at the end of the Siq, making it the first and most striking thing a visitor to Petra would see — an appropriate position for a royal cenotaph designed to advertise the power and sophistication of the Nabataean state to every merchant, diplomat, and traveler who entered the city.

The Royal Tombs and the Urban Fabric of Petra

Beyond the Al-Khazneh, Petra opens up dramatically into a broad valley several hundred meters across, with the ruins of the ancient city's built structures scattered across the valley floor and the great carved facades of the Royal Tombs cut into the cliff face that forms the eastern wall. The Royal Tombs — the Urn Tomb, the Corinthian Tomb, the Palace Tomb, and the Silk Tomb — represent a second spectacular sequence of rock-cut architecture that rivals the Treasury in ambition if not quite in delicacy.

The Urn Tomb, the largest of the group, has a facade of considerable scale, and its interior chamber is unusually large. In the Byzantine period, the chamber was converted into a Christian church, and a Greek inscription records its dedication in 446 CE — evidence of the continuity of life in Petra even after its economic decline. The Corinthian Tomb takes its name from its Corinthian capitals, which are similar to those of the Al-Khazneh but executed with less precision. The Palace Tomb, so named because its multi-story facade resembles the architectural appearance of a grand Roman palace, is the widest of the group, measuring approximately 46 meters across. The Silk Tomb derives its name from the extraordinary swirling color patterns in the sandstone of its facade, which shift through an almost iridescent range of reds, purples, and golds, resembling watered silk. These color patterns are the result of the geological layering of the sandstone, the result of millions of years of mineral deposition, and they could not have been designed — only discovered and chosen.

The valley floor of Petra is dominated by the Colonnaded Street, the main processional and commercial avenue of the city in the Roman period, which ran roughly east-west through the center of the city. In its Roman-period form, the Colonnaded Street was lined with approximately 106 columns and was flanked by shops and public buildings. Its paved surface, parts of which survive, preserves the flagstones that once covered it completely.

Among the religious structures in the valley, the Great Temple stands out as one of the largest freestanding structures ever built by the Nabataeans. Excavated by Brown University archaeologists beginning in the 1990s, the Great Temple complex covers approximately 7,560 square meters and includes a lower temenos (sacred precinct), a triple-arched propylaea, a colonnaded lower walkway, and an upper temple structure that contains an extraordinary feature: a small theater-like space in the interior of the temple itself, with rows of seats cut from the rock, suggesting that some form of communal gathering — religious ceremony or civic assembly — took place within the sacred space.

The Temple of the Winged Lions, located just north of the Colonnaded Street, is another significant Nabataean religious building, named for the pairs of winged feline creatures that decorated its column capitals. It was dedicated to a female deity, possibly Atargatis (the Nabataean goddess associated with water and fertility), and it continued in use through the Roman period.

The Petra Theater, carved into a hillside north of the Colonnaded Street, is a rock-cut structure of considerable size, with approximately 45 rows of seats and a capacity estimated at around 8,500 spectators. Originally Nabataean and significantly modified during the Roman period, it represents the Nabataeans' engagement with the theatrical and entertainment traditions of the Hellenistic world — a further indicator of how thoroughly this desert trading people had absorbed and adapted the cultural forms of the wider ancient Mediterranean civilization.

The Monastery: the Forgotten Colossus

Of all the rock-cut monuments of Petra, the one that most consistently surprises visitors in terms of sheer scale is not the Treasury but the Monastery, known in Arabic as Al-Deir, which stands alone at the end of a long climb high above the main archaeological zone. The Monastery is reached by ascending a staircase of approximately 800 rock-cut steps that wind up a natural ravine on the western side of the city, a climb of roughly 45 minutes that passes through a landscape of extraordinary geological beauty before emerging on a plateau at the summit where the monument suddenly fills the view.

The Monastery measures approximately 50 meters wide and 45 meters tall, making it larger in its overall dimensions than the Treasury, though it is simpler in its decorative elaboration. The facade is clearly related to the Treasury in its architectural vocabulary — the same arrangement of Corinthian columns, broken pediments, and a central tholos — but it is executed with a certain boldness and simplicity that makes it feel less like a jewel and more like a declaration. The name "Monastery" dates from the Byzantine period, when the structure was converted for use as a Christian church; crosses carved into the interior walls are evidence of this reuse. The original Nabataean function was almost certainly the same as the Treasury — a royal tomb or a high-status funerary monument.

From the plateau in front of the Monastery, the view westward toward the Wadi Araba and the distant hills of the Negev is one of the finest in all of Jordan. The plateau also contains several other carved monuments and niches, and a small cafe that has been welcoming exhausted climbers with refreshments for decades. The effort of the climb is universally judged worth it by those who make it, and the experience of standing before the Monastery's vast facade in relative solitude (compared to the crowds at the Treasury) is one of the most powerful the Petra site offers.

The High Place of Sacrifice

Near the top of a ridge known as Jabal Madbah, reached by a staircase cut from the living rock on the north side of the main valley, lies the High Place of Sacrifice — a stone platform high above the city that served as a Nabataean open-air cult site. The High Place consists of a large rectangular courtyard cut into the summit of the ridge, with an altar block at the center, two obelisks carved from the rock at the eastern end, and a large circular basin cut in front of the altar for the collection of ritual liquids. There are also smaller basins cut into the rock surface around the altar area.

The two obelisks, each approximately 7 meters tall, are carved from the native rock of the ridge top — meaning they are not free-standing constructions but the original sandstone that has been left standing while the surrounding rock was cut away. They are believed to represent Dushara and Al-Uzza, the two principal deities of the Nabataean pantheon. The view from the High Place encompasses most of the main archaeological zone of Petra far below, and the effect of standing on this elevated platform, with the entire city visible as a miniature landscape in the valley, gives a sense of the command that the Nabataean religious tradition must have exercised over the life of the city — the gods watching from above, the sacrifices conducted in their sight with the city as a backdrop.

The path down from the High Place on the western side of the ridge passes through a series of rock-cut monuments and carved channels before descending through the Garden Triclinium to the valley floor. This route is known as the Processional Route, and it may have been used for religious processions that moved from the city below up to the High Place for festival ceremonies.

The Nabataean Religious World

The religion of the Nabataeans remains incompletely understood, partly because they did not leave extensive written theological texts and partly because their religious practices drew on multiple traditions and changed over time. The chief male deity was Dushara, a god associated with the power of the mountains and the fertility of the land, often represented as an uncarved, elongated block of black stone — a form of divine presence that required no human face and no narrative iconography, just the pure presence of the sacred within a shaped stone. This aniconic tradition (the worship of a deity through an abstract form rather than a figurative image) is characteristic of certain ancient Semitic religious traditions and has been compared to the ancient traditions of standing stones in the Levant and Arabia.

The chief female deity was Al-Uzza, associated with the planet Venus, with water, and with fertility, who was syncretized at various times with the Greek Aphrodite, the Egyptian Isis, and the Mesopotamian Ishtar. The Nabataeans also worshipped Al-Lat, another goddess associated with the sun and with vegetation, and Manat, a goddess of fate. These three goddesses — al-Uzza, Al-Lat, and Manat — are mentioned in the Quran in a context that scholars have interpreted as a reference to pre-Islamic polytheistic practices in Arabia, indicating that the Nabataean religious world was part of a broader Arabian religious landscape that was still active at the time of the emergence of Islam in the seventh century CE.

The Nabataeans conducted their religious rituals at open-air high places like the one on Jabal Madbah, at carved shrines in the rock faces throughout the city and its surrounding countryside, and at freestanding temple buildings such as the Temple of the Winged Lions. Feasting in honor of the gods appears to have been a significant element of their religious practice: many of the monuments in Petra include carved triclinia (dining rooms) adjacent to the tomb facades, suggesting that memorial banquets were held at the tombs of the dead, with the deceased symbolically participating in the meal.

The Roman Period: Conquest and Continuity

For all the magnificence of the Nabataean kingdom at its peak, the political independence of the Nabataean state came to an end not through military defeat in the field but through a process of political absorption that scholars still debate in its details. In 106 CE, the Roman Emperor Trajan sent his forces into the Nabataean kingdom, and the last Nabataean king, Rabbel II, who had died in 106 CE, left behind no heir capable of resisting Roman pressure. The Nabataean kingdom was transformed into the Roman province of Arabia Petraea, with its capital at Petra and later at Bostra in modern Syria.

The Roman period at Petra was not one of decline, at least not initially. Roman investment in infrastructure brought new building to the city, and the Colonnaded Street, the Triumphal Arch, and the nymphaeum (public fountain) visible in the archaeological record today date substantially to the Roman period or to Nabataean construction upgraded by the Romans. The population of the city may have continued at similar levels through the first and second centuries CE. The Nabataeans themselves, as a people and a culture, did not disappear — they continued to live in Petra and throughout the former kingdom, gradually being absorbed into the Roman provincial culture and eventually, like much of the Levant, converting to Christianity.

What changed under Roman administration was the direction of the trade routes. As Rome developed maritime trade routes through the Red Sea, the overland caravan routes that had been the source of Petra's wealth became less vital. The city of Palmyra in Syria gradually took over the northern caravan routes. Petra began a long, slow decline from which it would never fully recover.

The Earthquake of 363 Ce and the Decline of Petra

The most catastrophic single event in the history of Petra was the earthquake of May 19, 363 CE, a major seismic event that struck the entire eastern Mediterranean and was particularly devastating for the cities of the Jordanian plateau. At Petra, the earthquake destroyed large numbers of buildings, collapsed facades, and disrupted the water supply system that was the city's lifeline. The physical damage was enormous, but the earthquake also accelerated the social and economic processes that were already undermining the city's significance.

By the time of the earthquake, Petra's role as a commercial hub had already been substantially diminished. The trade routes had shifted, maritime commerce through the Red Sea had taken over many of the overland routes, and the rise of Palmyra and other Syrian cities had reduced Petra's strategic importance within the Roman commercial network. The earthquake struck a city that was already declining, and its effects compounded the existing trends. Many buildings were not rebuilt, and the population of the city began to shrink.

The Byzantine period in Petra, from the late fourth through the sixth centuries, saw the city functioning as a Christian bishopric and a modest regional center rather than a great commercial capital. Churches were built, including the Petra Church — a triple-aisled basilica discovered in 1990 by archaeologist Kenneth W. Russell — which preserves an extraordinary series of mosaic floors covering approximately 140 square meters, depicting personifications of the Seasons, the Ocean, the Earth, and Wisdom alongside real and mythological animals and birds. The mosaics, dating stylistically to the early sixth century, are among the finest Byzantine mosaics surviving in Jordan. Around 600 CE, the church burned down in a fire that, paradoxically, preserved the mosaics by burying them under debris that protected them from the later iconoclast destruction of figural religious art that swept through the Byzantine world.

By the end of the sixth century and through the seventh, as the Arab conquests transformed the political landscape of the entire Near East, Petra faded further into insignificance. It was never entirely abandoned — the Bdoul, a Bedouin tribe, continued to live in the caves and rock-cut chambers of the site — but it ceased to function as a city and became instead a ghostly landscape of monuments inhabited by a small pastoral community.

The Crusader Period and Medieval Petra

The political fortunes of the region around Petra shifted dramatically in 1099 when the First Crusade successfully established the Latin Kingdom of Jerusalem in the Levant, and in the following decades the Crusader kingdom extended its reach southward into the territories east of the Jordan River. The region around Petra, known to the Crusaders as Oultre-Jourdain (Outremer Jordan), became a strategic frontier zone, and the Crusaders built several castles to defend it. The most notable of these in the immediate Petra area is the castle of Wu'eira (also known as Vaux Moise, "the Valley of Moses"), located a short distance from the main Petra archaeological site. Wu'eira occupies a rocky spur above a deep wadi and was constructed in the early twelfth century, serving as a military base for Crusader operations in the region. The castle was abandoned after Saladin's reconquest of the region in 1189. The site of Wu'eira today preserves the remains of towers, walls, and a moat cut from the rock, and it is a compelling testament to the medieval military history that overlays Petra's ancient layers.

The Crusaders were aware of the ancient ruins at Petra — their name for the area, "the Valley of Moses," reflects a tradition that associated the nearby spring of Ain Musa with the biblical story of Moses striking water from a rock in the desert — but they appear to have engaged with the ancient monuments primarily as sources of building material rather than as objects of curiosity or reverence. Stones robbed from Petra's ancient buildings appear in the fabric of Crusader-era constructions throughout the region. By the end of the Crusader period, Petra was effectively off the map of the Western world, its existence known only vaguely from ancient sources and from the oral traditions of the Bedouin who lived among its ruins.

The Rediscovery of Petra

For the peoples of the region — the Bedouin, the local Arab communities, the scholars and merchants of Damascus and Cairo — Petra was never truly "lost." The Bdoul tribe, whose ancestors had inhabited the site for generations, knew every chamber and canyon of the rose-red city. But for the European world, Petra had become a gap in the map, a classical city mentioned in ancient sources but unknown to modern eyes, its location a matter of scholarly speculation.

That changed on August 22, 1812, when the Swiss explorer and orientalist Johann Ludwig Burckhardt became the first European in the modern era to enter Petra and leave a written record of what he saw. Burckhardt was an extraordinary figure: a Swiss-born scholar who had spent years in the Middle East learning Arabic, mastering Islamic customs, and traveling in disguise as a Muslim merchant under the name Sheikh Ibrahim. He had heard rumors of a great ruined city in the mountains of what is now southern Jordan, and on the pretext of wanting to perform a sacrifice at a local holy site, he persuaded a local guide to lead him through the Siq.

Burckhardt's entry into Petra on that August day was brief — his disguise as a Muslim pilgrim made lingering too dangerous — but he saw enough to understand the extraordinary significance of what he had found. His account of the visit, published posthumously, described the approach through the Siq, the stunning first appearance of the Treasury, and the general character of the ruins he was able to observe during his necessarily rapid passage. His account sparked enormous interest in Europe and set in motion a sustained European engagement with Petra that continues to this day.

In the years and decades after Burckhardt, European travelers, archaeologists, and scholars arrived in increasing numbers, mapping and documenting the site, collecting inscriptions, and beginning the long process of understanding the Nabataean civilization that had created it. The early explorers faced significant challenges, including the resistance of the Bdoul tribe who viewed the site as their home and were understandably reluctant to welcome a stream of foreign visitors to their ancient chambers and courtyards. Over time, arrangements were made, and Petra gradually became one of the most visited archaeological sites in the Middle East.

The Bdoul and the Question of Inhabitation

For generations, the rock-cut chambers and caves of Petra were not merely archaeological monuments but living spaces, inhabited by the Bdoul tribe of Bedouin who had made the ancient city their home. The Bdoul — whose name may derive from a word meaning "those who were exchanged" or may reflect their origins as descendants of earlier inhabitants of the site — lived in many of the tomb chambers and natural caves scattered across the Petra basin, keeping livestock, harvesting the water from the ancient cisterns, and conducting a pastoral life within the ancient ruins.

In 1985, when Petra was inscribed as a UNESCO World Heritage Site, the Jordanian government undertook a process of relocating the Bdoul from within the archaeological site to a new village called Umm Sayhoun, located about a kilometer from the main entrance to the site. This relocation was controversial and has remained so: the Bdoul were deeply attached to their homes within the ruins, and the transition to modern housing in a purpose-built village was difficult for many families. Some members of the community continued to return to the site to sell goods to tourists or to maintain their connections to the ancient city.

The Bdoul's relationship with Petra represents a human continuity that parallels and complements the archaeological significance of the site. Their presence within the ruins for many centuries means that local knowledge of the site accumulated over generations, and some of the early European explorers who visited Petra depended on Bdoul guides who knew the landscape intimately. Today, many members of the Bdoul community work within the tourism industry at Petra, as guides, vendors, and horse handlers, maintaining their connection to the site that their families inhabited for so many generations.

Petra in Modern Culture

No single event in the modern history of Petra has done more to bring it to global awareness than the filming of Steven Spielberg's Indiana Jones and the Last Crusade in 1989, in which the Al-Khazneh serves as the exterior of the "Canyon of the Crescent Moon" and the location of the Holy Grail. The film, starring Harrison Ford and Sean Connery, was seen by hundreds of millions of people around the world and transformed Petra from a destination known primarily to archaeological enthusiasts and Middle East travelers into a global icon of adventure and mystery. The number of tourists visiting Petra increased significantly in the years following the film's release, and the Indiana Jones connection has remained part of the site's popular identity ever since.

Petra by Night is another celebrated aspect of the modern visitor experience. Several evenings a week, the pathway through the Siq from the entrance to the Treasury is illuminated entirely by candles — hundreds of paper bags containing lit candles placed on the ground along the entire route — creating a magical, low-lit procession through the narrow gorge that culminates in the Treasury illuminated by candlelight against the dark sky. The ceremony includes traditional Bedouin music performed in the open space before the Treasury's facade. The effect is profoundly different from the daylight experience: where the daytime visit is about the overwhelming visual power of the architecture, the nighttime ceremony is about atmosphere, intimacy, and a certain mysteriousness that seems entirely appropriate to a city that kept its secrets for so many centuries.

The Ongoing Excavation: a City Still Being Discovered

One of the most remarkable facts about Petra in the early twenty-first century is how much of it remains unexplored. Despite more than two centuries of archaeological work since Burckhardt's pioneering visit, and despite the efforts of dozens of national and international archaeological teams working at the site over the past several decades, it is estimated that only approximately 15 percent of the total extent of Petra has been excavated or systematically investigated. The remaining 85 percent lies beneath the desert surface, awaiting excavation.

Recent decades have brought significant new discoveries to Petra. Satellite and aerial imaging has revealed the presence of large buried structures that were previously unknown. Archaeologists from Brown University discovered the Great Temple complex in the 1990s, revealing a previously unknown major monument in the heart of the city. The Petra Church with its extraordinary mosaic floors was discovered in 1990. In 2016, researchers using satellite imagery identified a large previously unknown structure buried near the Petra basin, approximately 800 meters south of the Treasury, consisting of a massive platform and associated structures. The excavation of this structure is ongoing.

The University of Basel, the Brown University Petra Archaeological Project, the American Center of Oriental Research in Amman, and teams from Jordan's own Department of Antiquities have all contributed to the growing body of knowledge about Petra. Each season of excavation adds new data, new structures, and new insights into the life of the ancient city, while at the same time raising new questions. The Nabataean civilization, for all that has been learned about it, remains in many respects an enigma: their written language, a form of Aramaic script, gave rise to the Arabic alphabet, but the body of texts they left behind is relatively sparse, and much of what they thought, believed, and valued must be inferred from the physical evidence their extraordinary built environment provides.

Visiting Petra Today

Petra is located approximately three hours by road south of Amman, the Jordanian capital, and about one hour north of the port city of Aqaba on the Red Sea. The nearest town is Wadi Musa, which has grown over the past few decades from a small village into a substantial tourist town with hotels, restaurants, and services catering to the hundreds of thousands of visitors who come to Petra each year.

The site is managed by the Petra Development and Tourism Region Authority, which oversees the archaeological protection of the site, the management of visitor access, and the various visitor services within the site. Entry to the site requires a paid ticket, and the proceeds contribute to conservation work and to the wider development of the Petra region.

Horses, donkeys, and horse-drawn carriages are available for hire within the site for visitors who find the distances involved in seeing the main monuments too great to walk. The distance from the entrance to the Treasury, through the Siq, is roughly two kilometers; from the Treasury to the Royal Tombs is another kilometer; from the Treasury to the Monastery, up the 800 steps, is a climb of roughly an hour each way. To see the principal monuments of Petra on foot in a single day is possible but demanding, and many visitors choose to spend two or more days at the site.

The best light for photography at the Treasury is in the morning, when the rising sun illuminates the facade directly. The best time to avoid the largest crowds is to arrive very early in the morning or in the late afternoon. The Petra by Night experience, with its candlelit procession through the Siq, runs on Monday, Wednesday, and Thursday evenings from approximately 8:30 PM, and requires a separate ticket.

Jordan's political stability, its welcoming attitude toward international tourism, and the country's active promotion of Petra as its premier tourist attraction have made the site accessible to visitors from around the world.
