Fortifications

By 1865 there were 33 earthen fortifications in the Arlington Line. Fort Cass (1861) was part of this defensive strategy. Built on top of the rise east of this marker, this lunette fort was named for Colonel Thomas Cass, whose regiment constructed the fort.

The location of Fort Cass is in Arlington, Virginia, in Arlington County, at the intersection of Arlington Boulevard (U.S. 50) and 10th Street North, on the right when traveling east on Arlington Boulevard.  ( Source - Historical Marker Database )
