The “Stadthaus N1”, built in 1986 by architect Carlfried Mutschler, is a postmodern building in the Mannheim grid square N1. The venue is located on the site of the former “old department store”, a magnificent baroque building, which was partly destroyed in World War II. Today the Stadthaus N1 houses the Municipal Library, the council chamber of the Mannheim municipal council and a community hall, where most of the UTC events will take place.
