Fort Point is located at the southern side of the Golden Gate at the entrance to San Francisco Bay. This fort was completed just before the American Civil War, to defend San Francisco Bay against hostile warships. The fort is now protected as Fort Point National Historic Site, a United States National Historic Site administered by the National Park Service as a unit of the Golden Gate National Recreation Area.
The most famous example of Fort Point in a film is Alfred Hitchcock's 1958 thriller Vertigo, wherein Kim Novak's character Madeleine jumps into the San Francisco Bay in an apparent suicide attempt.
Fort Point is designated as California Historical Landmark #82, officially listed under the site's original name, Castillo De San Joaqu?n.Read article at Wikipedia
