Civil War Defenses in Washington Fort Reno

The Civil War Defenses of Washington were a group of Union Army fortifications that protected the federal capital city, Washington, D.C., from invasion by the Confederate States Army during the American Civil War. Some of these fortifications are part of a grouping of properties now managed by the National Park Service (NPS) and listed on the National Register of Historic Places. Others are parts of state, county, or city parks or are located on privately owned properties. A trail connecting the sites is part of the Potomac Heritage Trail. Parts of the earthworks of some such fortifications still exist; others have been demolished. A 19.5-mile long trail connecting some of the forts was designated as a National Recreation Trail in 1971.
