Trans-Allegheny Lunatic Asylum, Weston, West Virginia
The Trans-Allegheny Lunatic Asylum opened its doors to patients in 1864, and in the 1950s, the West Virginia facility reached its peak, housing more than 2,400 patients—even though it was designed to hold only 250. The severe overcrowding led to inhumane conditions (like lack of heat and convalescents kept in cages), and patients started acting increasingly violent, from starting fires to attacking staff members. The asylum finally closed in 1994, but the souls of some patients are said to linger. Ghost tours are available for those wishing to see how some patients lived—and died—within the cramped halls.
