Exclave

Alaska and Kaliningrad are both examples of exclaves.

While there has never been a macronational bedroom nation, some exclaves have been barely larger.

Spain’s Melilla, one of two small exclaves of EU land on the African continent, has long been the strongest distillation of fortress Europe.

France, but the shape of a giraffe, with a number of its counties belonging to Wales, with an odd little exclave far up North in Norway? That's border gore.
