Built of reinforced concrete in the early 20th century, Cellblocks 13 and 14 represent a distinct era of prison architecture. However, these prisoner-built structures were flawed from the start. The steel reinforcing bars of both buildings were placed too close to the concrete surface during construction, resulting in accelerated corrosion. Cellblocks 13 and 14 have long lacked even temporary roof protection since the prison’s abandonment in 1971. The reinforced concrete roofs remained exposed, allowing water to infiltrate the buildings and damage these historic structures.

This year, Eastern State completed long-overdue roof restoration projects on both buildings, finally protecting the structures for years to come. The project also included extensive sitework to tie into the site’s original 200-year-old brick sewer. The next phase of work will include façade repairs and interior stabilization.
