Ohio State Reformatory

The Ohio State Reformatory (OSR), also known as the Mansfield Reformatory, is a historic prison located in Mansfield. It was built between 1886 and 1910 and remained in operation until a 1990 federal court ruling (the 'Boyd Consent Decree') ordered the facility to be closed. The history of the Ohio State Reformatory began in 1861, the field where the reformatory would be built was used as a training camp for Civil War soldiers. The camp's name had significant meaning to Ohio as it was named Camp Mordecai Bartley in honor of the Mansfield man who served as Ohio governor in the 1840s
