The Sheboygan Municipal Auditorium and Armory was built in 1942 in the Moderne style, constructed with the assistance of the Works Progress Administration with the purpose of providing a space for the Wisconsin Army National Guard's 32nd Division. The building also took on the role of the primary venue for a variety of events in Sheboygan including meetings, rallies, concerts, and fairs. The building was also home to an early professional basketball team, the Sheboygan Red Skins. One of sixteen inaugural teams of the National Basketball Association (NBA), Sheboygan holds the record for the NBA’s smallest market, and the Auditorium and Armory holds the record for the NBA’s smallest arena.

The Auditorium and Armory, designed by local architect Edgar Stubenrauch, exhibits defining features of the Moderne style including its concrete and steel structure, flat roof, geometric designs and banding, spare exterior walls with decoration focused at openings, monumental scale, and blending of traditional and classical architectural elements with modern architectural design and materials.
