Deep within the walls of two of North America's most notorious prisons, the echoes of a violent past continue to resonate. From the brutal history of West Virginia's Moundsville Penitentiary to the dark, confined cells of the Old Cornwall Jail, these facilities hold the stories of inmates who faced unimaginable suffering and met tragic ends. Today, these sites are considered among the most haunted locations on the continent, where the lingering spirits of those who lived, suffered, and died within their walls are said to remain, forever trapped by the weight of their own histories and the cruelty they endured.
