How much do you know about Montgomery County’s forts?
This map covers the surrounding area of forts Alexander, Franklin, and Ripley, each built within a few miles of Washington D.C. near Glen Echo. Fort Sumner can be seen scribbled on the map in ink. It was connected to the other three forts by trenches. The forts were built as part of D.C.’s defenses during the Civil War. The illustration was created by the United States Army Corps of Engineers.
