The Colosseum Wilster is the largest hall operation in the Steinburg district. The historic building, which captivates from the outside with its brick framework and the two striking decorative towers, is located in the city centre and has been used mainly as a dance hall since its inauguration at the turn of the century. Even today, many dance events from discos to oldie nights still take place here. The hall is also used for company events, weddings, meetings and conferences. In 2019, the Schleswig-Holstein Music Festival will be a guest at this special venue for the first time.
