Fort MacArthur (San Pedro, Los Angeles, California)
San Pedro, Los Angeles · California · World War I, World War II, Cold War
History & Significance
Named after Lieutenant General Arthur MacArthur, whose son Douglas MacArthur would later command American forces in the Pacific during World War II, this coastal artillery post guarded a vital strategic harbor. Land acquisition began when President Grover Cleveland designated an area overlooking San Pedro Bay as an unnamed military reservation in 1888 to improve the defenses of the expanding Los Angeles harbor area.
In 1917, the Army completed four batteries of 14-inch disappearing carriage rifles and two batteries of 12-inch mortars on Point Fermin. More than 4,500 soldiers were stationed at the fort before the end of World War I. During World War II, the fort served as a training ground and induction center for Army troops headed for war, with over 750,000 troops passing through.
The fort evolved with military technology: during the early years of the Cold War, Fort MacArthur became a key part of the West Coast's anti-aircraft defenses, becoming the home base of the 47th Anti-Aircraft Artillery Brigade. The large guns were being removed by the end of World War II, with the last decommissioned in 1948. The Upper Reservation is now San Pedro's Angels Gate Park, home of the Korean Bell of Friendship, while the Fort MacArthur Military Museum, located at Battery Osgood-Farley, displays exhibits on the fort's history and role in defending Los Angeles.
