Top 5 Scariest Abandoned Prisons in the United States

Though the article originally states these are the "top 5 scariest abandoned prisons from around the world", I would think "North America" would be more appropriate, since they all reside within the United States.  On the list are:

Moundsville West Virginia Penitentiary

Ohio State Reformatory, also known as Mansfield Reformatory

Frontier Prison from Rawlings, Wyoming

Eastern State Penitentiary

Alcatraz from San Francisco
