This is one hell of a fucked up, geopolitical situation. This is a tiny piece of India, that up until recently, was surrounded by Bangladesh, which was surrounded by India, which was again, completely surrounded by Bangladesh. It’s like a messed up Russian doll situation of crazy borders.

This is what’s called a third-order enclave. An enclave is when a piece of one country’s territory is entirely surrounded by another country’s territory. Most of the strange areas like this were cleared up in 2015 between India and Bangladesh, but this unique enclave still exists, so you’ll need to show a passport a couple of times.
