Inscription: Historical Site Defenses of Washington 1861-1865 Fort Ethan Allen This embankment was the south face of Fort Ethan Allen, a bastioned earthwork built in September 1861 to command all the approaches to Chain Bridge south of Pimmit Run. The fort had a perimeter of 736 yards with emplacements for 39 guns. The embankments which still remain were the south face less the west bastion; an interior bombproof shelter for protection against artillery fire from Hall’s Hill; The magazine and guard house near the north face; and part of the east face. This marker is included in the Defenses of Washington marker series: [www.hmdb.org/marker.asp?marker=2317]
