Cresson is a massive institutional complex that began as the Cresson Tuberculosis Sanatorium (authorized in 1910, opened 1913), was later absorbed into the Lawrence F. Flick State Hospital system in 1956, then rebuilt into SCI Cresson—a state prison that operated from 1987 until its closure in 2013. Paranormal teams zero in on the abandoned cellblocks, infirmary spaces, and the utility tunnels beneath the grounds, with repeat claims of large shadow figures, disembodied voices/EVPs, and heavy footsteps/banging in sealed or empty wings
