For Fort Richardson, the U.S. Army installation adjacent to Anchorage, Alaska, see Fort Richardson.
Now marked only by an historic marker on South 18th Street off of Glebe Road, Fort Richardson was a detached redoubt constructed by the Union Army in September 1861 as part of the defense of Washington during the American Civil War. It was named for General Israel B. Richardson, whose division was then deployed to defend against attack by way of Columbia Turnpike. It had a perimeter of 316 yards and emplacements for 15 guns.
The fort is designated as an Historic District by Arlington County.
