at Fort Point had been dismounted and sold for scrap. The fort, moderately damaged in the 1906 earthquake, where the fort was used as a temporary refugee camp by the U.S Army, was used over the next four decades for barracks, training, and storage, however, in 1913, part of the interior wall was removed by the army in their short-lived attempt to make the fort the army detention barracks using soldier and prisoner labor. The detention barracks were later built on Alcatraz Island and was used until becoming a federal prison. Soldiers from the 6th U.S. Coast Artillery were stationed there during World War II to guard minefields and the anti-submarine net that spanned the Golden Gate. New quarters and administrative buildings were constructed on the higher ground, behind the new Endicott batteries, moving Fort Scott to this location. Preserving Fort Point In 1926 the American Institute of Architects proposed preserving the fort for its outstanding military architecture. Funds were unavailable, and the ideas languished.

It should be preserved and restored as a national monument." The fort is situated directly below the southern approach to the bridge, underneath an arch that supports the roadway. Preservation efforts were revived after World War II. On October 16, 1970, President Richard Nixon signed a bill creating Fort Point National Landmark status Fort Point is designated as California Historical Landmark #82, officially listed under the site's original name, Castillo De San Joaquín. Recreation The rocky point north of the fort produces waves, in the winter months, that are popular with surfers. Media use Fort Point is a popular filming location.

In film In Dark Passage (1947), a fight scene with Humphrey Bogart on the bluff above the fort ends with his opponent falling to his death in what is now the fort's parking lot. In the 1950 film The Man Who Cheated Himself, there is a five-minute search scene near the end of the film that was filmed at Fort Point and shows many shots of the fort. The most famous example is Alfred Hitchcock's 1958 thriller Vertigo, wherein Kim Novak's character
