Mouton Hall is sometimes called "Old" Mouton, to distinguish it from the newer building, F. G. Mouton. Offices and classrooms for Criminal Justice, Sociology, Anthropology, and Political Science are housed in Mouton Hall. Mouton Hall was named for members of the Mouton family of Lafayette. Alexander Mouton was the ninth governor of Louisiana and Julian Mouton was a member of the Circuit Court of Appeals. Other members of the prominent family donated land and money to aid UL Lafayette's growth. Mouton Hall was completed in 1940.
