Trans-Allegheny Lunatic AsylumFNC
This former state hospital for the mentally insane is part history site, part hotbed of paranormal activity. Ghosts of Civil War soldiers and former patients are said to be walking through the two and half miles of hallways. Visitors claim to see things move or feel the presence of spirits. The largest hand-cut stone building in North America, this mammoth granite structure was constructed in 1858. The asylum originally housed 250 residents at a time, but at its peak in the 1950s, more than 2,000 patients called this place home. Trans-Alleghany stopped treating patients in 1994, but brave thrill seekers can roam the halls on any number of special guided tours including a night-time flashlight ghost hunting experience.
