Holy See Factsheet

Customs and Culture

Cultural Attributes

The Holy See represents one of the most distinctive cultural entities in the world, functioning simultaneously as the governing body of the Roman Catholic Church and as a sovereign state recognized under international law. Its cultural identity is inseparable from the Catholic faith, which shapes every dimension of life within Vatican City — from its art and architecture to its daily rhythms and social customs. Latin remains the official language of the Holy See for formal documents, liturgical texts, and official communications, making it one of the very few institutions in the world where Latin retains an active administrative role. Italian is widely spoken in everyday interactions among residents and staff. The cultural heritage of the Holy See is expressed most visibly through its extraordinary collection of art and architecture. St. Peter's Basilica, the Sistine Chapel with Michelangelo's celebrated ceiling frescoes, and the Vatican Museums — which house over 20,000 works of art — represent some of the most significant cultural treasures in human history. The Vatican Apostolic Library, founded in 1475, contains approximately 1.1 million printed books and 75,000 manuscripts, serving as one of the oldest and most important research libraries in the world. The liturgical calendar governs the cultural life of the Holy See, with major feasts such as Christmas, Easter, and the feast days of patron saints marking significant communal celebrations. Papal audiences and liturgical ceremonies held in St. Peter's Square draw pilgrims and visitors from across the globe, reinforcing the Holy See's role as a center of universal Catholic culture. The Swiss Guard, established in 1506, remains an enduring cultural symbol — their Renaissance-era uniforms and ceremonial duties reflect a living connection to the institution's deep historical roots. The Pontifical academies, covering fields such as theology, science, and the arts, further demonstrate the Holy See's commitment to intellectual and cultural engagement across disciplines. Despite its remarkably small geographic size of approximately 44 hectares, the cultural influence of the Holy See extends to an estimated 1.3 billion Catholics worldwide, making it a uniquely global cultural force.

History

Historical Eras

  1. Early Papal Foundations

    326 – 756

    Following Constantine's legalization of Christianity, the first basilica was erected over Saint Peter's traditional tomb in 326, anchoring Rome as the spiritual center of Christendom. The papacy developed its theological authority and diplomatic reach across the crumbling Western Roman Empire. This era established the institutional foundations of the Holy See as both a religious and emerging political force in Europe.

  2. Papal States Era

    756 – 1054

    The Donation of Pepin granted the papacy temporal control over central Italian territories, formally establishing the Papal States as a sovereign political entity. Popes navigated complex relationships with Frankish and later Holy Roman emperors, asserting spiritual supremacy while defending territorial holdings. The era culminated in the Great Schism of 1054, which permanently divided the Roman and Eastern Orthodox churches.

  3. Medieval & Crusade Period

    1054 – 1417

    Pope Urban II launched the Crusades in 1095, projecting papal authority into the Holy Land and cementing the papacy's role as director of Western Christendom. The period witnessed intense conflicts with Holy Roman emperors, the sack of Rome by Henry IV in 1083, and the founding of military orders such as the Knights Templar. Papal prestige peaked with Innocent III before declining sharply during the Avignon papacy and the Western Schism.

  4. Renaissance Papacy

    1417 – 1648

    Restored to Rome after the Western Schism, the papacy became one of the great Renaissance patrons, commissioning Michelangelo's Sistine Chapel ceiling, Raphael's Vatican frescoes, and the rebuilding of St. Peter's Basilica, consecrated in 1626. The Protestant Reformation challenged papal authority across northern Europe, prompting the Counter-Reformation and the Council of Trent. This era defined Catholic identity and artistic heritage that endures to the present day.

  5. Loss of Temporal Power

    1648 – 1929

    The gradual erosion of papal secular authority accelerated dramatically when Victor Emmanuel's forces seized the Papal States in 1860 and captured Rome in 1870, declaring it the capital of unified Italy. Popes Pius IX and his successors refused to recognize the Italian state, confining themselves as self-declared prisoners within the Vatican. The standoff ended with the 1929 Lateran Treaties, which recognized Vatican City as an independent sovereign state and compensated the Holy See for its territorial losses.

  6. Vatican City State

    1929 – present

    The Lateran Treaties of 1929 created the modern State of Vatican City, the world's smallest sovereign state, resolving sixty years of dispute with Italy. A revised concordat in 1984 further adjusted church-state relations, removing Catholicism's status as Italy's official state religion. The Holy See has since expanded its global diplomatic presence, engaging with issues of religious freedom, international development, interfaith dialogue, and the moral dimensions of globalization under a succession of influential pontiffs.

Overview

Almost all of Vatican City’s citizens live inside the Vatican’s walls. The Vatican includes high dignitaries, priests, nuns, and guards as well as about 3,000 lay workers who comprise the majority of the work force.

The Holy See’s diplomatic history began in the fourth century, but the boundaries of the papacy’s temporal power have shifted over the centuries. From the 8th century through the middle of the 19th century, the Popes held sway over the Papal States, which included a broad band of territory across central Italy. In 1860, after prolonged civil and regional unrest, Victor Emmanuel’s army seized the Papal States, leaving only Rome and surrounding coastal regions under papal control.

In 1870, Victor Emmanuel captured Rome itself and declared it the new capital of Italy, ending papal claims to temporal power. Pope Pius IX and his successors disputed the legitimacy of these acts and proclaimed themselves to be "prisoners" in the Vatican. Finally, in 1929, the Italian Government and the Holy See signed three agreements resolving the dispute:

  • A treaty recognizing the independence and sovereignty of the Holy See and creating the State of the Vatican City;
  • A concordat defining the relations between the government and the church within Italy; and
  • A financial convention providing the Holy See with compensation for its losses in 1870.

A revised concordat, altering the terms of church-state relations, was signed in 1984.

Geography and Environment

The state of Vatican City is the smallest sovereign state in the world. A tiny enclave within the city of Rome, it occupies 109 acres and is almost completely surrounded by medieval walls. As a result of the Lateran Pacts of 1929, the Italian Government granted St. Peter’s Basilica and Square and the surrounding area within the Vatican walls as the Holy See’s sovereign and independent territorial base. Besides St. Peter’s, Vatican City also includes the Apostolic Palace, administrative and residential buildings, museums, archives, and libraries, a cemetery, and gardens covering almost one-third of the entire area. Thirteen other buildings in Rome, as well as the Pope’s summer residence at nearby Castel Gandolfo, enjoy extraterritoriality under the terms of the Lateran Pacts.

Economy

The Holy See operates a unique, non-commercial economy that is fundamentally different from those of sovereign states. As the ecclesiastical jurisdiction of the Roman Catholic Church, its finances are devoted to supporting the mission of the Pope, the Roman Curia, diplomatic missions worldwide, and various charitable, educational, and religious institutions. It does not engage in industrial production, agriculture, or commercial trade in any conventional sense, and it has no national debt market, stock exchange, or significant private sector.

Revenue is drawn from several principal sources. Peter's Pence, an annual collection from Catholic dioceses around the world, provides voluntary donations from the faithful to support papal activities and charitable works. Additional income comes from the management of real estate holdings in Rome and abroad, investment returns from a diversified financial portfolio, and contributions from dioceses and religious orders. The Vatican Museums generate substantial revenue through ticket sales, attracting roughly six to seven million visitors annually in normal years, alongside earnings from the sale of postage stamps, commemorative coins, and publications.

The Holy See uses the euro as its currency under a monetary agreement with the European Union, and it mints a limited number of euro coins bearing Vatican imagery, which are highly prized by collectors. The Institute for the Works of Religion, commonly known as the Vatican Bank, manages assets on behalf of clergy, religious institutes, and Catholic organizations, and has undergone significant reforms in recent years to align with international transparency and anti-money-laundering standards established by Moneyval, the Council of Europe's monitoring body.

Financial oversight has been substantially restructured under recent papacies, with the creation of the Secretariat for the Economy in 2014 and ongoing efforts to consolidate budgeting, auditing, and procurement functions. The Holy See has reported operating deficits in recent years, prompting cost-cutting measures, salary reductions for cardinals, and reforms to investment practices.

The workforce, numbering several thousand, includes clergy, religious, and lay employees engaged in administration, diplomacy, media, museum operations, and the Swiss Guard. Vatican City State, administratively distinct from the Holy See, manages its own budget tied largely to museum revenues and remains one of the few entities in the world whose economy is shaped almost entirely by religious purpose rather than market forces.

Visit the Vatican Apostolic Library, founded in 1475, holding about 1.1 million printed books and 75,000 manuscripts Papal audiences and liturgical ceremonies in St. Peter's Square draw pilgrims and visitors from around the world
What is the capital of the Holy See?
Vatican City serves as both the capital and the entire territorial extent of the Holy See, making it the smallest internationally recognized independent state in the world. Situated on the right bank of the Tiber River in Rome, the area was known in ancient times as Ager Vaticanus, a marshy lowland that later became the site of St. Peter's Basilica and the papal palaces. The Holy See's unique status as a sovereign entity was formally established by the Lateran Treaties of 1929.
Where is the Holy See located?
The Holy See is located within the city of Rome, on the Italian Peninsula in southern Europe. It constitutes an enclave entirely surrounded by Italy, representing the world's only nation-state fully enclosed within a capital city of another country. Despite its minuscule geographic footprint, the Holy See holds full sovereignty and maintains diplomatic relations with states across the globe, functioning as the central governing body of the Roman Catholic Church.
What countries border the Holy See?
Italy is the sole country bordering the Holy See, entirely surrounding Vatican City on all sides. The current boundaries were defined by the Lateran Treaties signed in 1929, which resolved decades of conflict following Italy's annexation of Rome in 1870 and the collapse of the Papal States. Before that annexation, popes had exercised secular rule over substantial portions of the Italian peninsula for more than a thousand years.
What religion is practiced in the Holy See?
Roman Catholicism is the overwhelmingly dominant religion of the Holy See, adhered to by approximately 99% of its population. This is unsurprising given that the Holy See is itself the supreme governing institution of the worldwide Catholic Church, with the Pope serving as its head. The Lateran Treaties of 1929 originally granted Roman Catholicism special status as Italy's state religion, though a 1984 concordat modified that arrangement, removing Catholicism's designation as the official religion of the Italian state.
What currency does the Holy See use?
The Holy See uses the Euro (EUR) as its official currency. Although not a member of the European Union, the Holy See reached a monetary agreement with the EU that permits it to use the Euro and issue a limited quantity of its own Vatican Euro coins, which are highly prized by collectors worldwide. These Vatican-minted coins are legal tender throughout the Eurozone but rarely circulate freely due to their scarcity and collectible value.
What languages are spoken in the Holy See?
Italian is the primary language of daily administration and communication within the Holy See, while Latin retains its status as the official language of the Catholic Church and is used in formal ecclesiastical documents, canon law, and liturgical contexts. French has historically served as the language of Holy See diplomacy, and the multilingual character of the institution means that numerous other languages are regularly used among the international clergy, Swiss Guards, and Vatican staff.
What is the Holy See known for?
The Holy See is known above all as the spiritual and administrative center of the Roman Catholic Church, leading over a billion faithful worldwide. St. Peter's Basilica and the Sistine Chapel — home to Michelangelo's celebrated ceiling frescoes — rank among the world's most visited and revered cultural landmarks. The Holy See is also recognized for its active role in international diplomacy and humanitarian affairs, engaging on issues ranging from religious freedom to conflict resolution in the Middle East. The papal election process, the conclave, captures global attention whenever a new pope is chosen.
