Fort Mason - History

History

The Civil War prompted the construction of a set of coastal defense batteries located inside the Golden Gate. Initially these defenses were built as temporary wartime structures rather than permanent fortifications and one of these was constructed in 1864 at Point San Jose, as the location of Upper Fort Mason was then known. A breast-high wall of brick and mounts for six 10-inch (250 mm) Rodman cannons and six 42-pounder guns were built on the site. Excavation in the early 1980s uncovered the well-preserved remains of the western-half of the temporary battery, and it has now been restored to its condition during the Civil War.

The fort was named Fort Mason in 1882, after Richard Barnes Mason, a former military governor of California.

President Grover Cleveland established the Endicott Board in 1885 for the purpose of modernizing the nation's coastal fortifications. Chaired by Secretary of War William Endicott, the board recommended new defenses at 22 U.S. seaports, deeming San Francisco Harbor second only to that of New York in strategic importance. As a result, an extensive series of forts, batteries, and guns were built on the harbor, including Fort Mason.

The piers and sheds of Lower Fort Mason were originally built from 1912 to warehouse army supplies and provide docking space for army transport ships. By this time, the US Army began to build new bases in Hawaii, the Philippines, and various other Pacific islands. Most of the material for those bases was shipped through San Francisco. By 1915, the three piers together with their associated warehouse had been completed, and a railroad tunnel driven under Upper Fort Mason to connect with the railroad network along the Embarcadero.

With these new facilities, Fort Mason was transformed from a harbor defense post into a logistical and transport hub for American military operations in the Pacific. The Army ferry General Coxe provided scheduled transportation from Fort Mason to the processing center at Fort McDowell on Angel Island up to eight times per day during the war.

During World War II, Fort Mason became the headquarters of the San Francisco Port of Embarkation, controlling a network of shipping facilities that spread across the Bay Area. Over the years of the war, 1,647,174 passengers and 23,589,472 measured tons moved from the port into the Pacific. This total represents two-thirds of all troops sent into the Pacific and more than one-half of all Army cargo moved through West Coast ports. The highest passenger count was logged in August 1945 when 93,986 outbound passengers were loaded.

The Korean War in the 1950s also kept the post busy, and in 1955 the San Francisco Port of Embarkation was renamed the U.S. Army Transportation Terminal Command Pacific. The embarkation operations continued through the early sixties. In 1965 the headquarters of the US Army Transportation Terminal Command were transferred to the Oakland Army Terminal, and most of Fort Mason's embarkation facilities fell into disuse. The Army continues to use and maintain the old officer housing. The National Park Service took over the administration of the site in the 1970s as a part of the Golden Gate National Recreation Area. In 1976 lower Fort Mason became the Fort Mason Center, a non profit organization that provides a destination for programs, events and organizations that support and reflect the evolving cultural fabric of San Francisco and the Bay Area.
