Located on 226 acres on the northeastern shore of Staten Island, Fort Wadsworth is one of the oldest military installations in the nation. Prior to its closing in 1994, Fort Wadsworth claimed to be the longest continually manned military installation in the United States, with the first use of the land for military purposes in 1663 as the site of a blockhouse. It served a variety of military purposes until 1995, when the United States Navy (who had been using it as the headquarters for the Naval Station New York since 1979) left.
Currently, it is part of the Staten Island Unit of Gateway National Recreational Area, maintained by the National Park Service. Fort Wadsworth is open to the public, and visitors can see a number of historic locations (including those on the National Register of Historic Places) through ranger-led guided tours through the National Park Service’s visitor center. The location also offers an overlook with panoramic views of the Upper Bay, Brooklyn and Manhattan.
