Background
Holmesburg Prison, given the nickname "The Terrordome," was a prison operated by the city of Philadelphia, Pennsylvania and the Pennsylvania Department of Prisons (PDP) from 1896 to 1995. The facility is located at 8215 Torresdale Avenue in the Holmesburg section of Philadelphia. It was decommissioned in 1995 when it closed. As of today, the structure still stands and is occasionally used for prisoner overflow and work programs. It was the site of controversial decades-long dermatological, pharmaceutical, and biochemical weapons research projects involving testing on inmates.
