Formerly known as the Pennsylvania State Lunatic Hospital, the Harrisburg State Hospital was the first public asylum in Pennsylvania. It opened in 1851 and operated until 2006. During the 1930s, electrotherapy was used on its patients. There have been reports of screams heard throughout the grounds, as well as in the underground tunnels beneath the buildings. The Ghost hunters for the Discovery Channel show Ghost Lab even heard the voices uttering full names.
