Every abandoned building in Pennsylvania has its own story; some are well-known, while others are lost to the pages of time. There’s one thing on which we can all probably agree, however, and that is those forgotten buildings often set our imagination on fire as we wonder what was and what might have been. A glimpse at the abandoned Creeson Prison in Pennsylvania might send a shiver down your spine as photos illustrate how life inside has simply stopped, preserved for perhaps as long as the buildings stand.

Perched atop Cresson Mountain, Cresson Prison’s story abruptly came to an end in 2013 due, in part, to the rising and unrealistic costs of its upkeep. Ever since, it has by in large stood abandoned.

Today the former prison beckons ghost hunters and curiosity-seekers, but its tale begins many years ago, long before it served as a medium-security prison, housing male inmates.

Andrew Carnegie sold the land on which the abandoned prison complex sits to Pennsylvania for just one dollar in 1911. The plan, initiated by Carnegie and developed by the state’s commissioner of health Samuel Dixon, was to build a sanatorium to care for tuberculosis patients.

At the time, many believed that the best treatment for tuberculosis was time outdoors to breathe in the fresh air and plenty of rest. Vitamin A and sufficient protein were also considered keys to combating TB.

The 500 acres on which the sanatorium would sit promised plenty of outdoor space for patients, and the complex would eventually include a collection of buildings, including for dining, housing, and administration.

Officially known as the Cresson Sanatorium, many simply referred to it as the “San.” While the first patients entered the sanatorium in January 1913, it wasn’t officially completed until June of that year.

Eventually, the complex expanded even further, with the addition of an elementary school (children were increasingly being diagnosed with TB), a playground, a nursing school, and even a pool.

Thousands of patients came through the doors, though some never left, during its history as a sanatorium, which would transition purposes in late 1956. It then became the Allegheny State Hospital, caring for those with mental illnesses.

After several more name changes, the facility was shuttered in 1982.

Its final transition to SCI Allegheny, a medium-security correctional facility, would occur in 1984. The institution thrived for nearly three decades before closing permanently in 2013.

While the buildings may have been left abandoned, they still trigger the imagination – especially of ghost hunters. Some claim that more than 40,000 people perished at Cresson Sanatorium and Prison while the prison housed some notorious inmates, including serial killer Joseph Kallinger.

With such a storied history, it comes as little surprise that the former sanatorium is rife with tales of the paranormal. Those who have visited tell of feeling both a dark energy and as though they’re being followed if they visit the abandoned TB hospital.

Some have seen apparitions while others tell of hearing voices or strange sounds when no one is there. The tales are so rampant, in fact, that ghost hunts are hosted regularly at the abandoned tuberculosis hospital and Pennsylvania prison.
