This hospital was a sanitarium (insane asylum). It is said that many disturbed spirits wonder the halls, campus, and woods around it. Rumors have it, that many mental patients were mistreated, neglected, even tortured! This place is very old and you can tell somethings not right when you walk up the hill and immediately get cold chills!
