Traditionally a hotspot for paranormal activity, the casemates are a popular spot for investigation. They seldom disappoint.
They were originally constructed as a fort defense when Fort Mifflin was rebuilt after the Revolution. (1798 - 1801).
Casemate 1 is the first of the casemates and is the largest. It was used as a barracks and as a prison cell for Confederate prisoners during the Civil War. It served in this capacity from 1863 - 1865.
Each of the following casemates: 2 - 5, were also used as prison cells.
Every casemate has had paranormal activity. Casemates 4 and 5 have been the location of the most aggressive and violent manifestations.
What we have documented in Casemates 1 - 5 appears here:
