SCI Cresson - Cresson, Pennsylvania, USA - Retired Prisons on Waymarking.com

"What began as the Cresson Tuberculosis Sanatorium when it opened in 1913 morphed over the years into a state hospital and finally a state prison (SCI Cresson).
The Cresson Tuberculosis Sanatorium treated more than 40,000 patients suffering from tuberculosis between 1913 and 1964. The sanatorium opened as both a hospital and long-term residential care facility, to treat both individuals and entire families who had tuberculosis.
SCI Cresson opened in 1987 as a medium-security correctional facility for male inmates.
SCI Cresson closed June 30, 2013, with the State citing the antiquity of the prison and rising costs of maintaining it as the primary reasons for the closure.
Now SCI Cresson sits mostly abandoned on a parcel of land just off of Route 22 between Altoona and Ebensburg.
I said mostly abandoned because at least part of the former prison grounds is now being used by a new company for a new purpose. Big House Produce took over the SCI Cresson campus in late 2019 with plans to build hydroponic equipment, grow hydroponic produce and hemp, and develop sustainable energy projects on the property.

Though the day-to-day focus of Big House Produce is on growing crops and building equipment for other hydro farmers, they began offering photographers and explorers a chance to tour portions of the former prison in May of 2021, as a way to help offset the costs of restoring vandalized infrastructure more quickly.
The portion of the prison grounds graciously made available for tours by the folks at of Big House Produce and it is MASSIVE! Visitors should read the ground rules before visiting, so that you are prepared to safely explore the former prison grounds." Source
