If you’re standing in the middle of St. Peter’s Square, you’ve basically crossed an international border without even showing a passport. It’s wild. You’re in a place that is roughly one-eighth the size of New York’s Central Park.
Vatican City is the world smallest country, and it’s not even close.
While most of us think of countries as sprawling landscapes with forests, highways, and suburbs, this one is just 0.17 square miles. That is about 100-ish acres. Honestly, some Texas ranches are five times bigger than this entire sovereign nation. But don’t let the footprint fool you. Despite being the world smallest country, it exerts more global influence than nations ten thousand times its size.
Why the World Smallest Country is a Legal Miracle
Most people assume "small" just means a tiny island or a rock in the ocean. But Vatican City is landlocked. It’s completely surrounded by the city of Rome. You can walk across the entire country in about twenty minutes if you’re moving at a decent clip.
It hasn't always been this way.
The history is kinda messy. For centuries, the Popes ruled over a massive chunk of Italy called the Papal States. Then, in the mid-1800s, Italy decided to become one unified country and basically took all that land back. The Popes weren't happy. They retreated behind the Vatican walls and stayed there for almost 60 years, calling themselves "prisoners."
Basically, it was a giant geopolitical standoff.
It wasn't until 1929 that things got settled. Benito Mussolini—yes, that Mussolini—signed the Lateran Treaty with the Holy See. This created the independent State of the Vatican City. It’s a "sui generis" entity, which is a fancy way of saying it’s one-of-a-kind. It is an absolute monarchy where the Pope holds all the power: executive, legislative, and judicial.
A Population Unlike Any Other
The demographics here are bizarre. As of early 2026, the population is roughly 764 to 800 people. But here is the kicker: nobody is actually from here.
You can’t be born a Vatican citizen.
There are no maternity wards. No public schools. No playgrounds. Citizenship is "jus officii," meaning it’s granted based on your job. If you’re a cardinal living in Rome, or a member of the Swiss Guard, or a high-ranking diplomat, you get a Vatican passport. The second you stop working that job, the passport is revoked. Usually, you just revert back to being Italian.
- The Swiss Guard: They are the colorful soldiers you see in the striped uniforms. They have to be Swiss, Catholic, and single (at least when they start).
- The Clergy: Most residents are priests or nuns working for the central administration of the Church.
- The "Commuters": Thousands of Italians enter the world smallest country every single day to work in the museums, the post office, or the pharmacy, but they go home to Rome at night.
The Economy of a Country Without Taxes
How does a 100-acre country make money? They don't have an income tax. They don't have a GDP in the traditional sense.
Basically, the Vatican runs on "spiritual tourism" and investments.
The Vatican Museums are a massive revenue generator. Think about it: millions of people pay about €20 to €30 to see the Sistine Chapel every year. Then you have the souvenirs. Vatican stamps are legendary among collectors. Since the country has its own postal system, you can’t use Italian stamps there. People love the novelty of mailing a postcard from the world smallest country.
They also use the Euro. They aren't in the European Union, but they have a special agreement that lets them mint their own coins with the Pope’s face on them. Those coins are worth way more than their face value to collectors.
Surprising Facts About the World Smallest Country
There are things about this place that just don't make sense until you realize it’s a tiny city-state trying to act like a superpower.
- Highest Crime Rate? Statistically, yes. This is a math quirk. Because there are only 800 residents but millions of tourists, the number of pickpockets per capita is technically the highest in the world. It’s a bit of a "lies, damned lies, and statistics" situation.
- The Latin ATM: The Vatican has the only ATMs in the world that offer instructions in Latin. If you want to withdraw cash, you might see "Inertito scidulam" (Insert your card).
- No Photography in the Sistine Chapel: This isn't actually for religious reasons. In the 1980s, a Japanese TV corporation funded a massive restoration of the chapel and, in exchange, they got the exclusive rights to photos and videos. Even though that contract expired years ago, the ban stuck.
- The Secret Archives: They aren't actually secret. The name "Archivio Segreto" comes from a mistranslation. It actually means "Private Archive." Scholars can get in, but you need a lot of credentials.
Is There Anything Smaller?
You might have heard of Sealand. It’s an old World War II platform off the coast of England. A guy declared it a country in the 60s and started selling titles like "Lord" and "Baroness."

While Sealand is physically smaller, it isn't a real country.
In international law, you need recognition. No other government recognizes Sealand. Vatican City, on the other hand, has diplomatic relations with almost every country on Earth. It has a seat at the UN (as a Permanent Observer). It’s a real, functioning state.
Visiting the World Smallest Country in 2026
If you’re planning a trip, things have changed a bit post-2024. The crowds are back to record levels. Honestly, if you show up without a plan, you’re going to spend four hours standing on a sidewalk in Rome looking at a brick wall.
The Dress Code is Real
Don't show up in shorts or a tank top. They will turn you away at the door of St. Peter’s Basilica. Your knees and shoulders must be covered. It doesn't matter if it’s 95 degrees outside. I’ve seen people buying overpriced paper ponchos from street vendors just to get inside.
Book Your Museum Tickets Early
In 2026, the Vatican Museums are using a strict timed-entry system. You need to book at least 60 days in advance on the official website. If you miss that window, you’ll have to pay a "skip-the-line" premium to a third-party tour operator, which usually costs double.
The Dome Climb
If you aren't claustrophobic, climb the dome of St. Peter’s. There is an elevator that takes you halfway, but the rest is a narrow, winding staircase that tilts with the curve of the dome. The view from the top gives you the best perspective of the world smallest country. You can see the entire border from one spot.
Actionable Next Steps
If you're fascinated by the world smallest country and want to see it for yourself, here is exactly what you should do:

- Check the Papal Calendar: Before you book, check vatican.va to see if there is a Papal Audience or a major feast day. These days are incredible for the atmosphere but a nightmare for navigating crowds.
- Download a High-Res Map: Rome and the Vatican blend together. Having a map that clearly shows the 1929 border walls helps you understand exactly when you are "leaving" Italy.
- Mail a Postcard: Go to the yellow post office trucks in St. Peter's Square. It’s one of the few tangible ways to prove you’ve been to a different country.
- Look Beyond the Art: While the Sistine Chapel is the star, look for the "Vatican Gardens" tours. They are limited-entry and show you the parts of the country where the residents actually live and walk.
The world smallest country proves that sovereignty isn't about how much land you have. It's about history, recognition, and a really good legal team. Whether you go for the religion, the Renaissance art, or just the weirdness of a 100-acre monarchy, it’s a place that shouldn't exist—yet it does.
