exclave

n. territory or culturally distinct entity surrounded by the territory of another country

In political geography, an enclave is a country or part of a country mostly surrounded by the territory of another country or wholly lying within the boundaries of another country, and an exclave is one which is geographically separated from the main part by surrounding alien territory. Many entities are both enclaves and exclaves, but not all are simultaneously both.
