Built in 1927 by the Southern Prison Company of San Antonio, this was the third structure to serve as Montague County Jail. The first floor contained living quarters for the jailer and his family, and six prison cells were maintained on the second floor. The building was used as a jail until a new facility was built in 1980, and its architectural features include an entry portico, stone cornice, cast stone window sills, and simple tile detailing.
