Town hall replacing old town hall and adjacent buildings destroyed in 1945 British air raid. A competition was held between 1959 and 1963. Construction started in 1968. The result is a two-winged, dynamically bent building complex with a hexagonal council hall in front. Formwork-rough columns, prefabricated parapet elements, staircases in cast-in-place concrete and monumental concrete reliefs - the entire structure is defined by different variants of exposed concrete, both inside and out. Circumferential escape and rescue balconies horizontalize the office floors, while the one- to two-story roof zone is irregularly rhythmicized according to special uses by the canteen, bell floor and mayor's office. The second floor stands out as a projecting representational piano nobile: its angular, bay-like projections stand on sculptural supports, and the façade surface is further accentuated by the bush-hammered concrete. The council chamber is set as a flatter building in front of the large administrative wing and separates the upper market square with its large staircase and fountain from the lower, smaller and greened part.
