You probably think you know the answer. Most people do. If you’ve ever sat through a pub quiz or flipped through a trivia book, the name "Vatican City" is burned into your brain as the default response to what country is the smallest country in the world.
It’s about 0.44 square kilometers. That’s roughly 109 acres. To put it in perspective, you could fit the entire country into New York’s Central Park about eight times over. It’s tiny. Really tiny.
But here’s the thing: being the smallest isn’t just about land area. It’s about the weird, borderline-absurd logistical reality of running a sovereign nation that is literally surrounded by a city wall. We’re talking about a place where you can’t technically be "born" a citizen, where the "national" ATM speaks Latin, and where the crime rate—at least on paper—is technically the highest in the world.
Honestly, it’s less of a country and more of a theological-artistic complex with its own zip code.
Why Vatican City is the Smallest Country in the World—By a Mile
If you look at the "Top 5" list, the competition isn't even close. Monaco, which is second on the list, is nearly five times larger than the Vatican. Nauru and Tuvalu are massive islands by comparison.
The Vatican’s borders are essentially defined by the Leonine Walls and a white line painted on the ground at the edge of St. Peter’s Square. That’s it. Cross that line, and you’re in Italy. Step back, and you’re in a sovereign state governed by an absolute monarchy.
The Top 5 Tiny Titans (by area):
- Vatican City: 0.44 $km^2$
- Monaco: 2.02 $km^2$
- Nauru: 21 $km^2$
- Tuvalu: 26 $km^2$
- San Marino: 61 $km^2$
While the other "microstates" on this list are actual pieces of land with residential neighborhoods and public beaches, the Vatican is basically a collection of museums, a giant church, and some very fancy gardens.

The Citizenship Nobody Keeps
This is where it gets weird. In every other country, you get citizenship by being born there (jus soli) or through your parents (jus sanguinis).
Not here.
You cannot be born a Vatican citizen. There are no delivery rooms. There are no hospitals. Citizenship is granted jus officii—by virtue of your office. Basically, if you work for the Holy See in a high-capacity role (like being a Cardinal or a member of the Swiss Guard), you get a passport.
But here’s the kicker: it’s temporary. If you lose your job or retire, your citizenship is revoked. You don't become "stateless," though. Under the Lateran Treaty of 1929, anyone who loses Vatican citizenship and doesn't have another one automatically becomes an Italian citizen.
As of early 2026, the population is hovering around 764 people. But only about half of those people actually live inside the walls. The rest are diplomats living in Rome or elsewhere.
The High Crime Rate "Myth"
You might have heard that the smallest country in the world is also the most dangerous.

Statistically? Yes.
In reality? Not really.
If you calculate the number of crimes per capita, the Vatican’s numbers go through the roof. This is because the population is under 800, but they get millions of visitors every year. In 2025—a Jubilee year—the Vatican saw an estimated 33.5 million pilgrims.
When you have 33 million people passing through a tiny space, you’re going to get pickpockets. When you divide those thousands of petty thefts by a "resident" population of 800, it looks like every citizen is a career criminal. In truth, there isn’t even a formal prison system inside. They have a few cells for pre-trial detention, but if you’re actually sentenced to time, Italy handles the incarceration (and the Vatican picks up the tab).
Money, Wine, and Latin ATMs
The Vatican is the only country on Earth that is a UNESCO World Heritage site in its entirety. But it’s also a place of strange everyday quirks.
- The Wine Consumption: For years, statistics have suggested the Vatican has the highest wine consumption per capita in the world. People joke about the "blood of Christ," but the real reason is simpler: it’s a tiny community of mostly adult males who eat together in halls, and they have access to a duty-free supermarket where wine is incredibly cheap.
- The Economy: They don't have taxes. Zero. The income comes from the "Peter's Pence" (donations), museum entrance fees (which are substantial), and the sale of stamps and coins. Collectible Vatican euros are a huge deal for numismatists.
- The ATM: If you go to the Vatican Bank (IOR), the ATM gives you the option to conduct your business in Latin. It’s probably the only place on the planet where "Insert Card" is phrased as Insere chartulam.
The 2025/2026 Jubilee Impact
We just came off the back of the 2025 Holy Year. This was a massive deal. The "Holy Doors" of the four major basilicas were opened, and the influx of people was staggering.
The death of Pope Francis in April 2025 and the subsequent election of Pope Leo XIV brought even more attention to this tiny enclave. For only the second time in history, a Jubilee year was opened by one Pope and closed by another.

The sheer pressure of 33 million people on 100 acres of land meant that Rome and the Vatican had to complete over 3,000 construction projects leading up to 2026. If you visit now, the city is probably the cleanest and most "renovated" it’s been in a century.
Is it actually a "Country"?
Some people argue the Vatican isn't a "real" country because it doesn't have a permanent population that reproduces. However, in the eyes of international law, it's a sovereign state.
It has its own flag. It has its own anthem (Inno e Marcia Pontificale). It has a national football team—though they mostly play other microstates or police teams. They even have a telescope in Arizona (the Vatican Advanced Technology Telescope) because light pollution in Rome makes it impossible to see the heavens properly from home.
Tips for Navigating the Smallest Country
If you’re planning to visit the smallest country in the world, don’t just show up and expect to walk in.
- The Dress Code is Non-Negotiable: If your knees or shoulders are showing, you aren't getting into St. Peter's or the Museums. It doesn't matter how hot it is in Rome.
- Book the Museums Weeks in Advance: Ever since the 2025 surge, "walk-up" tickets are a fantasy. If you don't have a QR code on your phone, you'll be standing in a line that wraps around the Leonine Walls for four hours.
- The Post Office: It’s a cliché for a reason. The Vatican post office is famously more reliable than the Italian one. Buy a postcard, buy the stamp, and mail it from the blue mailbox inside the territory. It actually gets where it's going.
Ultimately, the Vatican remains a total anomaly. It’s a 16th-century absolute monarchy surviving in the middle of a 21st-century secular democracy. It is a place where the world's smallest army (the Swiss Guard) still wears uniforms designed centuries ago but carries modern SIG Sauer pistols.
It’s small, sure. But its footprint on history, art, and global politics is larger than most continents.
Actionable Next Steps
- Check the Liturgical Calendar: Before booking a trip, check the Vatican's official schedule. If there is a Papal Audience (usually Wednesdays) or a major feast day, St. Peter’s Square will be inaccessible for casual wandering.
- Verify Passport Requirements: While there are no border checks between Italy and the Vatican, you still need your passport for identification if you have a pre-booked "Scavi Tour" (the necropolis under the basilica).
- Download the Official Vatican Apps: These provide real-time updates on museum closures and crowd densities, which are essential in the post-Jubilee 2026 travel landscape.
