Even though the government feared an attack on the fort, one never came. The presence of the fort was possibly one of the reasons why such an attack never happened - it showed the Union had power on the Pacific Coast, and the facilities to protect any assets coming out of the west. With no action during the Civil War and no threat after the war, the fort transitioned into an army barracks. When plans for the Golden Gate Bridge were established there was a worry that the fort would be demolished. Chief Engineer Joseph Strauss realized the value of the fort and ordered the construction of the bridge to take place over the fort.
Since the civil war, the army has continued to use the fort for multiple purposes, having been used as both a barracks and training ground. It has also been used as a machine shop, a welding shop and as a storgae area. Before the construction of Alcatraz, the Army considered using it as a military detention center. Though the fort was originally constructed for defensive purposes, the brick structure became obsolete for defence with the invention of rifled artillery.
Today, the fort is part of the Golden Gate National Recreation Area. This area also includes the Fort Point National Historic site, Alcatraz Island, Golden Gate Bridge Pavilion, and several others. The site is now open to the public with historical exhibits and a bookstore. There are daily tours and cannon loading demonstrations.
