I, along with other colleagues, surveyed cell block 11 at Eastern State Penitentiary (ESP). Led by David Cornelius professor of architecture at Drexel University and an expert at historic preservation. Our survey is part of ESP goal to completely survey the Penitentiary so they may continue their ongoing preservation efforts.
Eastern State is unique in that they want to preserve the Penitentiary in a ruined state while keeping it a safe place for tourists to visit.
