リバティ島
Liberty Island and Ellis Island have been the property of the United States government since 1800 and 1808, respectively. Historical circumstances have led to the unusual situation of Liberty Island and of Ellis Island being exclaves of New York, both completely surrounded by New Jersey. The dominion, jurisdiction, and sovereignty of the islands have variously been the subject of a colonial land grant, a provincial governor's directive, and an interstate compact, as well as several court cases and a U.S. Supreme Court decision. Liberty Island and the acreage on Ellis Island are part of New York City which are completely surrounded by the municipal borders of Jersey City, including created by land reclamation at Ellis Island and riparian areas. Jurisdiction not superseded by the federal government falls to the appropriate state, New Jersey for the 24 acres, New York for the remaining 3.3 acres.
