The 10 Craziest Borders in the World

Borders are supposed to be simple: a line separating one country from another. But in reality, the world is full of strange quirks, bizarre lines on maps, and downright confusing places where two nations meet. From towns split in half to airports that straddle borders, here are 10 of the craziest borders in the world.

1. Baarle-Hertog/Baarle-Nassau (Belgium/Netherlands)

This small town is the poster child for messy borders. It consists of a patchwork of Belgian enclaves inside the Netherlands — and even Dutch enclaves inside those Belgian ones. The border runs through streets, cafes, and even people’s living rooms. You could literally eat dinner in Belgium and step a few feet into the Netherlands for dessert.

2. Diomede Islands (USA/Russia)

Just 2.4 miles of sea separate Little Diomede (USA) and Big Diomede (Russia), but they’re worlds apart. Between them runs the International Date Line, meaning when it’s Sunday on the American island, it’s already Monday on the Russian side. Locals joke you can “see tomorrow” just by looking across the water.

3. Derby Line/Stanstead (USA/Canada)

In these twin towns, the border cuts straight through buildings. The Haskell Free Library and Opera House has its entrance in the U.S., its bookshelves in Canada, and the reading room straddling both. You can sit in one chair and technically be in two countries at once.

4. Mount Everest (Nepal/China)

The world’s tallest mountain is also a border. The summit of Everest lies exactly on the line between Nepal and Tibet (China). Climbers ascending from either side meet at the top, technically standing in two countries at once while enjoying one of Earth’s most incredible views.

5. Bir Tawil (Egypt/Sudan)

This is one of the strangest borders because it’s a piece of land nobody wants. Thanks to conflicting maps, Egypt and Sudan both claim another nearby area but reject Bir Tawil. That makes it a “terra nullius,” or no man’s land — a rare unclaimed piece of Earth.

6. Hotel Arbez (France/Switzerland)

This cozy hotel is sliced in half by the border. Built in the 19th century, it has bedrooms with the headboard in Switzerland and the foot of the bed in France. Guests can literally sleep with their head in one country and their feet in another.

7. Panmunjom (North Korea/South Korea)

At the famous DMZ, blue conference huts straddle the line between North and South Korea. Inside, the border runs across the center of the conference table. Officials can sit on opposite sides, each in their own country, while technically sharing the same room.

8. Cooch Behar Enclaves (India/Bangladesh)

Until 2015, this area was the world’s most confusing border. There were over 160 tiny enclaves — Indian land inside Bangladesh, and Bangladeshi land inside India, some several layers deep. It created bizarre situations where people were citizens of one country but completely surrounded by the other.

9. Tumen River (China/North Korea/Russia)

Near the far northeast corner of North Korea lies one of the world’s shortest and most unique tripoints. China, Russia, and North Korea all meet here. You can literally stand in one spot and look into all three countries at once — though crossing is not exactly encouraged.

10. Pheasant Island (France/Spain)

This tiny island in the Bidasoa River changes nationality every six months. France and Spain take turns controlling it, a tradition dating back to the 17th century. It’s the ultimate example of shared custody in geopolitics.
