Fort MacArthur Museum, San Pedro
Some of the displays exhibits and vehicles and equipment underground in the fort. Fort MacArthur, a U.S. Army post which guarded the Los Angeles harbor from 1914 to 1974. The Museum was established in 1985, and it is housed in the corridors and galleries of historic Battery Osgood-Farley.
At the fort there were four batteries housed at the site and each battery is protected under 12 feet of concrete, with walls from 16-30 feet thick. Each battery had a massive 14 inch seacoast gun. They were like giant disappearing rifles, coz once they fired they could retract back into loading positions and set up to fire again behind 20-foot thick parapets in less than 22 seconds....... peek-a-boo I see you...... BLAM !!!! Thy could hit their target about 14 miles away..... OUCH!! More facts here www.ftmac.org/osgood-farley.htm
