The Vatican City is a landlocked sovereign city-state entirely surrounded by the Italian capital, Rome. It is the smallest independent country in the world by area — occupying less than one square kilometre — and is an ecclesiastical state that functions as the central government of the Roman Catholic Church. Although geographically tiny, the territory holds an outsized cultural, religious and diplomatic role: it is the residence of the Pope and the seat of the Holy See.

Characteristics and institutions

Vatican City contains a number of key institutions and sites associated with the Catholic Church and papal government. These include St. Peter’s Basilica and its square, the Apostolic Palace (the papal household and administrative offices), the Sistine Chapel, and the Vatican Museums, which preserve vast collections of religious art and historical objects. The governance of the state is closely linked to the Holy See — the ecclesiastical jurisdiction under papal authority — which carries out diplomatic relations and maintains representation at the international level.

The modern state of Vatican City was created in 1929 by the Lateran Treaty, an agreement between the Holy See and the Kingdom of Italy that established Vatican City as an independent sovereign entity. The treaty resolved decades of dispute dating to the 19th-century unification of Italy and the end of the Papal States. The pope serves as head of state and exercises both spiritual leadership of the Catholic Church and temporal authority over the city-state's institutions.

Culture, art and public life

Vatican City is renowned for its artistic heritage. Frescoes, sculptures and architectural masterpieces created by artists such as Michelangelo, Bernini and Raphael draw millions of visitors. Religious ceremonies, papal audiences and liturgical celebrations are central to daily life and to the city-state’s global presence. The economy is supported by donations, museum admissions, the sale of publications and stamps, and limited financial activities tied to its religious and cultural mission.

Governance, security and distinctions

The pope is sovereign of Vatican City, but much of the day-to-day administration is delegated to bodies and officials appointed by the Holy See. The Pontifical Swiss Guard provides ceremonial and personal protection for the pope. Vatican City is notable for being one of the world's few city-states and one of three countries that are completely enclosed by another country. It issues its own passports, coins and stamps, and its laws and protocols reflect a unique fusion of religious tradition and modern statecraft.

Notable facts and further reading

Many visitors come to admire the architecture, attend public audiences, or study the Vatican’s archives and collections. While its territory is small, Vatican City continues to exert influence through the moral and diplomatic authority of the Holy See, its cultural heritage and its global network of dioceses and charitable organizations.
