Geography is messy. You look at a map and expect clean lines, but reality is basically a jigsaw puzzle where someone stepped on the pieces. Most of us think of a country as a solid block of land, yet the world is full of little pockets and political anomalies that defy logic. This is where we get into the weeds of what is an enclave, a term that sounds like a spy movie setting but is actually a headache for border patrol agents and a fascinating quirk for travelers.
Honestly, it’s easy to get confused. People mix up enclaves and exclaves all the time.

Think of an enclave as a hole in a donut. The donut is the "surrounding" country, and that little hole is a totally different sovereign territory. If you want to get technical, an enclave is a piece of land that is totally surrounded by the territory of one other state. It’s landlocked in the most extreme sense of the word. You can’t leave without stepping into another country.
The Weird Reality of Being Surrounded
Why does this even happen? Usually, it’s a leftover from ancient treaties, royal marriages, or colonial maps drawn by guys who never actually visited the land they were dividing. History is stubborn.
Take Vatican City. It’s the world’s most famous enclave. You’ve got a whole country—the headquarters of the Catholic Church—sitting smack in the middle of Rome, Italy. If you walk out of St. Peter’s Square, you’re in Italy. Walk back in, you’re in the Holy See. It’s tiny. It’s barely 0.19 square miles. But it has its own post office, its own radio station, and its own laws.
Then you have San Marino. It’s much bigger than the Vatican, but it’s still entirely wrapped in the embrace of Italy. It’s one of the oldest republics in the world. Why isn't it part of Italy? Basically, because they stayed out of the messy wars of Italian unification in the 1800s. They gave refuge to Garibaldi, the Italian revolutionary, and in return, he let them keep their independence. Respect.
But there is a catch.
Not every enclave is a whole country. Sometimes, it’s just a "pipsqueak" piece of a country sitting inside another. This is where the term exclave comes in. If you are a resident of Kaliningrad, you are in an exclave of Russia, but you aren't in an enclave because you have a coastline on the Baltic Sea. To be a "true" enclave, you have to be totally surrounded by land.
The Absolute Chaos of Baarle-Hertog and Baarle-Nassau
If you want to see the concept of an enclave taken to a ridiculous extreme, you have to go to the border between Belgium and the Netherlands.
The town of Baarle is a nightmare for a GPS. It consists of Baarle-Hertog (Belgian) and Baarle-Nassau (Dutch). It isn't just one border line. It’s 22 Belgian enclaves inside the Netherlands, and several Dutch counter-enclaves inside those Belgian enclaves.
It’s inception, but with tax laws.
You’ll see white crosses painted on the sidewalk. One side is "B" for Belgium, the other is "NL" for Netherlands. These lines go through houses. They go through restaurants. Legend has it that back when Dutch law required restaurants to close earlier than Belgian law, diners would simply move their tables to the Belgian side of the room to finish their wine. There’s a "front door" rule here: your nationality is determined by where your front door is located. If the border splits your door, you basically get to pick.
This mess dates back to 1198. It was all about land swaps between the Dukes of Brabant and the Lords of Breda. They never bothered to clean it up, and now it’s a tourist attraction that proves humans can coexist in the weirdest geographical setups imaginable.
When Geography Becomes a Problem
While Baarle is charming and quirky, being an enclave can be a massive logistical pain. Imagine trying to manage a power grid or a sewage system when your neighbor is a different country with different regulations.
Lesotho is a prime example of a "nation-state enclave." It is entirely surrounded by South Africa. Because it’s a high-altitude, mountainous kingdom, it has plenty of water, which it actually sells to South Africa. But for almost everything else—imports, fuel, access to the sea—it is completely dependent on its neighbor. If South Africa closes the border, Lesotho is effectively trapped. This creates a power dynamic that is incredibly delicate.
The Difference Between Political and Ethnic Enclaves
We shouldn't confuse these sovereign territories with ethnic enclaves. You've definitely heard of Chinatown or Little Italy. These aren't sovereign states. You don't need a passport to go buy dim sum in San Francisco.
An ethnic enclave is a neighborhood with a high concentration of a specific cultural group. It’s a sociological thing, not a geopolitical one. Geographers focus on the borders; sociologists focus on the people. Both are called "enclaves," but only one involves international law and border guards.
The Enclaves That Finally Vanished
Until recently, the border between India and Bangladesh was the most complicated place on earth. It was home to the Cooch Behar enclaves. We are talking about 162 different pockets of land.
It got truly stupid. There was a third-order enclave called Dahala Khagrabari. It was a piece of India, inside a piece of Bangladesh, inside a piece of India, inside Bangladesh.
People living there were basically stateless. They couldn't access schools or hospitals in the surrounding country because they were "foreigners," but their own government couldn't reach them to build infrastructure. In 2015, the two governments finally did a land swap. Most of these enclaves were dissolved, and thousands of people finally got to choose a single nationality and stay there. It was a rare moment where world leaders decided that clean lines were more important than ancient land claims.
Why Do We Keep Them?
You’d think in 2026 we’d have simplified all this. But we don't. Why?
- National Pride: People living in an enclave often feel a fierce connection to their "motherland" across the border.
- Tax Havens: Some enclaves, like Campione d'Italia (an Italian village inside Switzerland), benefit from weird tax rules and currency perks.
- Historical Inertia: Changing a border is a legal marathon. Most countries would rather just deal with the weirdness than go through the paperwork.
Campione d'Italia is a fun one. It’s Italian territory, but it uses the Swiss Franc. It used to be famous for its casino, which was a major source of income until it hit financial trouble. The town is physically in Switzerland but the people are Italian. If they want a pizza, they might be paying Italian VAT but using Swiss coins. It's a localized identity crisis.
Essential Takeaways for the Curious
If you're looking to visit or study these places, keep a few things in mind. First, don't assume the rules of the "outer" country apply to the "inner" one. If you drive from Spain into Llívia (a Spanish enclave in France), you are technically back in Spain, even though you never saw a mountain range or a major sea change.
Second, check your phone roaming. Your carrier might think you're in France while you're standing in a Spanish town square, and that "international" data charge is no joke.
Lastly, appreciate the absurdity. These places exist because history is long and humans are sentimental about their dirt.
Next Steps for Geography Nerds:
- Map Check: Open Google Maps and search for Baarle-Hertog. Zoom in until you see the "NL" and "B" markings on the buildings.
- Verify Travel Docs: If you plan to visit an enclave like Kaliningrad (exclave) or Lesotho, remember that you are crossing international borders. Even if it looks like a short hop, you need the right visa for the destination and the surrounding country if you plan to drive back out.
- Study the Land Swap: Look up the 2015 India-Bangladesh Land Boundary Agreement to see how modern diplomacy actually fixes these "holes" in the map when they become a humanitarian crisis.
