Closed Mondays: The Fort MacArthur Museum
Deep in the earth beneath the hills of San Pedro lie cold cement corridors once used by the military for radio transmissions, to house soldiers, and to arm gun batteries. Sometimes only a few feet in width, and with the danger of sudden drops to the floor below, the bunker doors are now welded shut to discourage intruders.
Parts of Fort MacArthur, Battery John Barlow and Saxton, and the Paul D Bunker (added after the bombing of Pearl harbor) are closed off deep in the hills. The cliffs overlooking the Pacific are home to over a dozen gun batteries once armed with live artillery, including Anti-aircraft guns. The area is well-preserved. Magazine doors and an overhead rack for moving shells remain in the Battery John Barlow even today.
