During its more than 100 years in operation, the Moundsville Penitentiary in West Virginia was one of America’s most violent correctional facilities and the final stop for almost 1,000 criminals. The prisoners lived in cramped quarters, which led to riots. Many men were hanged or killed in the electric chair, while others were murdered by other prisoners. The prison closed in 1995, but according to some, the tortured spirits are still behind bars and in the bowels of the prison and may be seen or heard on a tour.
