Vatican City, the smallest independent state in the world, is a unique enclave nestled within Rome, Italy. As the spiritual and administrative center of the Roman Catholic Church, it wields significant influence far beyond its modest size.
Established as an independent city-state in 1929, Vatican City is home to iconic religious and cultural landmarks, including St. Peter’s Basilica and the Sistine Chapel. Governed by the Pope, it operates with its own laws, economy, and even a small but historic military force.
Here are 10 fascinating facts about this remarkable city-state.
Vatican City Facts
1. The Smallest Country in the World
Vatican City holds the title of the smallest country in the world, both in terms of physical size and population. Covering an area of only about 44 hectares (110 acres), it is nestled entirely within the city of Rome, Italy.
Despite its tiny footprint, the Vatican wields significant global influence through its status as the spiritual and administrative center of the Roman Catholic Church.

With a population of around 800 people, mostly clergy and members of the Swiss Guard, it operates as a sovereign city-state with its own governance and laws, a true microstate with monumental impact.

2. Headquarters of the Roman Catholic Church
As the epicenter of the Roman Catholic Church, Vatican City serves as the residence of the Pope, the leader of more than a billion Catholics worldwide. The Apostolic Palace is not only the Pope’s home but also the administrative heart of the Church.
The Vatican plays a crucial role in guiding Catholic doctrine, managing global church operations, and fostering interfaith dialogue. Its spiritual leadership extends far beyond its borders, influencing religious and political discourse globally.
3. Independent Since 1929
Vatican City’s status as an independent state was solidified through the Lateran Treaty signed on February 11, 1929, with Italy. This treaty resolved the “Roman Question,” a long-standing conflict that began in 1870 when the Papal States were annexed by the newly unified Kingdom of Italy.

The agreement recognized the sovereignty of the Holy See and provided compensation for the loss of the Papal States, ensuring Vatican City could function as an autonomous entity. This independence allows the Vatican to maintain neutrality and act as a mediator in international conflicts.
4. No Permanent Citizens
Vatican City does not have citizens in the conventional sense. Instead, citizenship is granted to individuals due to their professional roles within the city-state, such as clergy, members of religious orders, and the Swiss Guard.
This citizenship is typically temporary and tied to their service. Once their duties conclude, individuals return to their original nationality. This unique approach to citizenship supports the Vatican’s ecclesiastical and diplomatic missions without creating a permanent populace.

5. Home of St. Peter’s Basilica
St. Peter’s Basilica is one of the most iconic and sacred sites within Vatican City. It is believed to be built over the tomb of Saint Peter, one of Jesus Christ’s apostles and the first Pope.
The basilica is a masterpiece of Renaissance and Baroque architecture, with contributions from legendary artists such as Michelangelo, who designed its iconic dome.
The interior is adorned with stunning artwork, and the basilica serves as the site of many important liturgical events led by the Pope. It is also a major pilgrimage destination, drawing millions of visitors annually.
6. The Sistine Chapel and Michelangelo
The Sistine Chapel is another architectural and artistic jewel within Vatican City. It is renowned for its ceiling frescoes painted by Michelangelo between 1508 and 1512. These frescoes include “The Creation of Adam,” one of the most famous works of art in the world.
The chapel is not only a major tourist attraction but also plays a pivotal role in the Catholic Church. It is here that the Papal conclave is held to elect a new Pope, with cardinals gathering under Michelangelo’s frescoed ceiling to make this critical decision.

7. The Swiss Guard: The Vatican’s Army
Established in 1506 by Pope Julius II, the Swiss Guard is the world’s oldest continuously active military unit. Despite their colorful Renaissance uniforms, the Swiss Guard is a well-trained security force responsible for the Pope’s safety and the security of Vatican City.
Recruits must be Swiss nationals, Catholic, single, and have completed basic training with the Swiss military. In addition to their ceremonial duties, the guards are equipped with modern security training and technologies to address contemporary threats.
8. A Unique Economy
Vatican City’s economy is distinctive and largely non-commercial. It relies significantly on donations from Catholics worldwide, known as Peter’s Pence, which support charitable initiatives and church operations.
Additional revenue streams include sales from postage stamps, souvenirs, museum tickets, and publications. The Vatican operates without the typical industries of a nation-state and instead channels its resources into religious, educational, and cultural endeavors.
The economy is managed with a focus on supporting its global religious mission and maintaining the city-state’s infrastructure.
9. The Vatican Museums

The Vatican Museums are among the world’s most renowned and visited cultural institutions, housing an extraordinary collection of art and historical artifacts amassed over centuries.
Established in the early 16th century by Pope Julius II, the museums include an impressive range of works from ancient Roman and Egyptian artifacts to masterpieces from the Renaissance and beyond. Notable sections of the museums include the Raphael Rooms, the Gallery of Maps, and of course, the Sistine Chapel.
The museums attract millions of visitors each year, generating significant revenue for the Vatican and contributing to its mission of cultural preservation and education. The Vatican Museums not only showcase the Vatican’s rich history of artistic patronage but also serve as a bridge between faith, history, and the global community.
10. Owns a Bank: The Istituto per le Opere di Religione (IOR)
Vatican City operates its own financial institution, officially named the Istituto per le Opere di Religione (Institute for the Works of Religion), commonly known as the Vatican Bank. Established in 1942, the bank primarily manages assets and funds for the Catholic Church and its affiliated institutions, including charitable organizations, dioceses, and religious orders.
The Vatican Bank is unique among financial institutions as it is not a typical commercial bank; it does not provide services to the general public. Over the years, the bank has been involved in various financial controversies and scandals, prompting reforms to improve transparency and accountability.
These reforms, initiated under Pope Benedict XVI and strengthened by Pope Francis, have aimed to align the bank with international financial standards and bolster its reputation as a trustworthy institution. Despite its small scale, the bank plays a critical role in managing the Church’s financial resources and supporting its global humanitarian and religious activities.
