Construction of the Hartington City Auditorium began in the spring of 1922 and was completed in 1923. The building was designed by Sioux City architect, William Steele, who formerly worked for Louis H. Sullivan, a prominent member of the Chicago School of Architecture. Listed on the National Register of Historic Places, it is an outstanding example of the Prairie style.
