History & Significance

After the Spanish-American War of 1898, the Army turned its attention toward the Marin Headlands and constructed five powerful batteries at Fort Barry between 1901 and 1905 that represented Endicott period upgrades: Battery Mendell, Battery Alexander, Battery Smith-Guthrie, Battery Samuel Rathbone, and Battery Patrick O'Rorke. Fort Barry is one of the best examples of an Endicott Period army post in the Golden Gate National Recreation Area.

The post buildings were finished in spring 1907, and the first occupants, the 161st Company of the Coast Artillery Corps, moved in on February 12, 1908. The Fort Barry buildings were designed in the Colonial Revival architectural style, featuring clean, simple lines and minimal applied decoration, with large, stocky symmetrical buildings with classical elements.

Fort Barry was without a permanent garrison from 1922 to 1941, but was regarrisoned at the beginning of World War II. Its final defense construction was a Nike missile site, SF-88, comprising an administrative complex, a control site on Wolf Ridge in Fort Cronkhite with radar equipment, and a launching site.

Fort Barry was discontinued as a U.S. Army installation effective September 10, 1974. The lands were given over to the National Park Service.
