Fort Tilden Historic District

Fort Tilden, also known as Fort Tilden Historic District, is a former United States Army installation on the coast in the New York City borough of Queens. Fort Tilden now forms part of the Gateway National Recreation Area, and is administered by the National Park Service.

Fort Tilden Historic District is located on the Rockaway Peninsula, between Jacob Riis Park to the east and Breezy Point Tip to the west. All three of these sites are operated by the National Park Service.Since its decommissioning, the former installation has largely become a natural area of beaches, dunes and maritime forest. Most of the old military installations are abandoned, and military structures which formerly housed artillery and ammunition are covered in graffiti.
