Fort Abercrombie State Historical Park

A National Historic Landmark, this park contains the remnants of World War II coastal defenses, including a pair of 203-millimeter Mark VI guns that could blast 109-kilogram (240-pound) shells a maximum of 32 kilometers, or 20 miles, offshore. Though artillerymen fired practice mortars, the battery never took aim at enemy planes, which only ventured to within 200 kilometers (124 miles). Don’t miss snapping the classic photo from inside one of the clammy concrete bunkers, which frame a slice of Monashka Bay.
