To Defend A Nation

Built to defend the river approach to  Washington, DC, Fort Washington has stood as silent sentry for over 200 years. As technologies advanced so did Fort Washington, from the brick and stone of the 19th century to the concrete and steel of the 20th century.  Joining the National Park Service in 1946, the park continues to protect the Potomac River.
