1. Coastal Mines Marker
This marker is outside of the fort near the food court.
Inscription. Harbor mines and cables fill the pier during the Second World War. Built in 1906, the mine-storage building (background) now houses the visitorís center. (Inscription below the title) Countering the threat of the submarine, the U.S. military mined the nationís ports---conventional artillery, like Fort Warrenís 15-inch guns, couldnít destroy underwater invaders. Beginning in 1898, the Coast Artillery placed minefields in maritime channels north and south of Georges Island (some minefields were further north, near Lynn). To avoid damaging friendly ships, soldiers in casemates (bunkers) controlled the mines via underwater cables. The cables were checked for short-circuits in water-filled concrete tanks (now below the food-service area) before being transported with the mines on railway cars to the docks.

Welcome to Fort Warren-It was built more than 150 years ago-a fort on an island, a key to the coastal defense of a new nation. It was transformed into a prison during the Civil War, housing hundreds of Confederates within its granite walls, ordinary soldiers and high level politicians alike. It served our nation for more than 85 year as a vigilant sentinel in the harbor. It made over into a park is an extraordinary island setting. Welcome to Fort Warren, on Georges Island. Welcome to the Boston Harbor Islands National Recreation Area.
