Replica of the prisoners barracks.  Unlike Andersonville, where Union prisoners were forced to find their own shelter, Confederate prisoners where housed in wooden barracks

Since Fort Delaware was an active coastal defense fortification, the prison camp was actually outside of the Fort on the grounds to the North.  Only high ranking prisoners (Confederate Gen. Archer) were kept within the forts walls.  These series of photos show the prison grounds.

Prison grounds from the north wall of Fort Delaware.  The ground was covered with wooden buildings.  There were also canals that criss-crossed the island to control flooding.  The prison camp extended well beyond the tree line in the distance
