Nestled between Egypt and Sudan, this 2,060 $km^2$ territory is a legal anomaly. Due to a 100-year-old border dispute, if either country claims Bir Tawil, they must legally give up their right to a much more valuable, resource-rich coastal area nearby!

In a world where nations usually fight for every inch of territory, Bir Tawil is a 2,060 km² area of sand and rock that has been officially "abandoned" by its neighbors, Egypt and Sudan.
The confusion started over 100 years ago when the British Empire drew two different maps:
Here is the catch: International law only allows a country to follow one map.
Because the Hala'ib Triangle is much larger and wealthier, neither country will touch Bir Tawil. Claiming the small desert would be a legal admission that they don't own the "big prize" next door. This makes Bir Tawil the only place on Earth (outside Antarctica) that is habitable but officially belongs to no one.
