Fort Monroe guards the mouth of the harbor at Hampton and Norfolk. It is the largest stone-and-brick fort built by the US. Constructed after the War of 1812, the Fort remained in Union hands during the Civil War, and was the place where Confederate President Jefferson Davis was imprisoned after the war. Today the Fort is run by the National Park Service.
