Fort Mason, in San Francisco, California originated as a coastal defense site during the American Civil War. The nucleus of the property was owned by John C. Frémont and disputes over compensation by the United States continued into 1968. In 1882 the defenses were named for Richard Barnes Mason, a military governor before statehood. Fort Mason became the headquarters for an Army command that included California and the Hawaiian Islands from 1904 to 1907. In 1912 the Army began building a port facility with piers and warehouses to be a home base for ships of the Army Transport Service serving Alaska, Hawaii, the Philippines and other Pacific Army posts and focus of Army supply for the Pacific. Today it is part of the Golden Gate National Recreation Area and the site of several cultural facilities. The entire fort area is listed as a historic district on the National Register of Historic Places, with 49 buildings of historic significance, spread over 1,200 acres. While the lower port area is a National Historic Landmark District, designated for its role in World War II. For more information please visit Wikipedia.
