The Columbia County Jail is a historic structure at Calhoun and Jefferson Streets in Magnolia, Arkansas. The brick two story structure in Columbia County was designed by Thompson & Harding and was built c. 1920, and is an excellent local example of Italian Renaissance architecture. It is faced in cream-colored brick, and has a terracotta hipped roof. It has an entrance portico with round arches supported by slender columns and gargoyles at its corners.[1]
The building was listed on the U.S. National Register of Historic Places in 1982 for its architecture; it was still used as a jail at that time.[1]
