Beautiful views of the moat! Built in 1908, this two story building was originally used by the army for ordinance storage (ammunition, artillery, tools, equipment, etc.). Potential historical tax credits are available. Fort Monroe is surrounded by eight miles of panoramic waterfront views of the harbor of Hampton Roads and the Chesapeake Bay. It is home to the largest stone fort with the largest moat in America. On the 565-acre barrier spit that is Fort Monroe.
