Behind the Door
Built between 1896 and 1910, the Ohio State Reformatory in Mansfield served as a detention center for young, petty criminals. The first inmates were admitted in 1896, and they helped construct the Romanesque Revival building. The reformatory closed in 1990 and was used most famously in the filming of The Shawshank Redemption (1994). Today it is open for tours, and has attracted a reputation for being haunted.
