Fort Flagler Information
3" gun Ft. Flagler.

Located at the northern end of Marrowstone Island, Fort Flagler was armed with eight 12-inch mortars, two 12-inch guns on altered gun-lift carriages, four 10-inch barbette guns and numerous smaller batteries. The army began construction on the fort in the mid 1890s and had completed most of the batteries by 1905. A battery of 3-inch antiaircraft weapons were emplaced near the southern border of the reservation in 1920, and moved to battery Rawlins during WW 2.

Fort Flagler is now a state park, and most of the batteries and all of the fire control stations are open to the public.
