Orange Grove Hospital, founded in 1956 was once a jail. Five prisoners were hanged in the jail, their bodies buried on the grounds in an upright position. Some believe this position prevents their spirits from finding eternal rest. At one time, the hospital, though considered cutting edge suffered from strange happenings about 10 years after its conversion from a prison. It abruptly closed in 1990 when in an unprecedented event, staff and patients killed each other for no apparent reason. It is rumored that the prisoners' bodies that were buried on the grounds possessed both staff and patient that fateful night. 

Other ghostly sightings include an apparition of a nurse in a white uniform that roams the hospital. She died in 1956 in a malfunctioning elevator from a broken neck. The ghost, known as Nurse Karen, haunts the maternity wing, and some say they see her watching people when they enter. Witnesses see her wandering the facility. 

There have been 16 deaths reported as urban explorers wandering the defunct hospital wind up violently killed, all of them having their necks broken in bizarre accidents.

Many visitors report hearing disembodied crying and moaning. People also claim to hear phantom footsteps and banging on the walls. Some visitors have complained of having sudden pains or the sensation of being touched and getting scratches and  deep cuts when they enter the surgery wing.

Formerly named Westerly State Penitentiary,  the hospital is located in the rural ghost town had its prison opening in 1865 and remained in use until it was closed in 1946. The imposing complex has 7 buildings. Once, it served up to 900 prisoners each year.
