Vatican City: A Tiny Nation Full Of Surprises
The Vatican is home to fewer than 1,000 official residents, yet it technically has the highest crime rate per capita in the world.

10 Vatican City Facts You Didn’t Know

1. The World’s Smallest Country by Area and Population
Vatican City covers just 44 hectares (110 acres), making it the smallest independent country in the world. Its population typically fluctuates around 700–900 people, most of whom are clergy, Swiss Guards, and administrative staff.
2. Highest Crime Rate Per Capita
Because it welcomes over 6 million tourists yearly, Vatican City technically reports more crimes per capita than any other nation. These are almost always petty thefts committed by nonresidents.
3. Home to the Only Bank ATMs in Latin
The Vatican Bank’s ATMs famously offer a Latin-language interface, making it the only place in the world where you can conduct modern banking in an ancient language.
4. No One Is Born a Vatican Citizen
Citizenship is granted only through appointment to a position—such as a member of the Swiss Guard or a Vatican diplomat. Once you leave the position, you lose the citizenship.
5. The Swiss Guard Is the World’s Oldest Standing Army
Established in 1506, the Pontifical Swiss Guard remains one of the oldest active military units. Their Renaissance-style uniforms are inspired by the designs often attributed to Michelangelo.
6. St. Peter’s Basilica Is Not the Pope’s Cathedral
Although often assumed to be the Pope’s main church, the cathedral of Rome is actually the Archbasilica of St. John Lateran. St. Peter’s Basilica, however, is the most iconic and visited site in Vatican City and contains the tomb of St. Peter.
7. It Has Its Own Euro Coins
The Vatican mints unique euro coins with designs featuring the reigning Pope. These limited-issue coins are highly collectible worldwide.
8. The Vatican Has an Astronomical Observatory
The Vatican Observatory—one of the oldest in the world—operates both in Castel Gandolfo and in Arizona, USA. Its mission is to advance scientific understanding, blending faith with cosmology.
9. Vatican City Has a Secretive, Highly Regulated Postal System
The Vatican Post is so famous for efficiency that many Romans prefer sending letters from Vatican mailboxes rather than Italy’s postal service. It processes millions of items yearly.

The Vatican Apostolic Library contains over 1.1 million printed books and countless manuscripts, some dating back over a thousand years.
