The native Lenape originally referred to Governors Island as Paggank ("nut island"). The name was translated into the Dutch Noten Eylandt, then Anglicized into Nutten Island, before being renamed Governor's Island by the late 18th century. The island's use as a military installation dates to 1776, during the American Revolutionary War, when Continental Army troops raised defensive works on the island. From 1783 to 1966, the island was a United States Army post, serving mainly as a training ground for troops, though it also served as a strategic defense point during wartime. The island then served as a major United States Coast Guard installation until 1996. Following its decommissioning as a military base, there were several plans for redeveloping Governors Island. It was sold to the public for a nominal sum in 2003, and opened for public use in 2005.
