Fort DuPont Park is a 376-acre (1.52 km²) wooded park under the management of the National Park Service located in Washington, DC. The name of the park comes from the old Civil War earthwork fort that lies within the park. The fort was one of several designed to defend Washington D.C. from a Confederate attack during the Civil War. There are few remains of the actual fortifications. The 400-acre site is one Washington D.C.’s largest parks and protects an important sub-watershed of the Anacostia River.
