Fort Washington Park

Fort Washington, located near the community of Fort Washington, Maryland, was for many decades the only defensive fort protecting Washington D.C. The original fort, overlooking the Potomac River, was completed in 1809, and was begun as Fort Warburton, but renamed in 1808. During the War of 1812, the fort was destroyed by its own garrison during a British advance.
