Located next to Oberkassel Bridge on the Rhine, Tonhalle is a fascinating building. It used to be a planetarium, but the only evidence left of its former incarnation is the dome-shaped roof. The Tonhalle is now the city's premier concert hall and hosts classical, jazz, rock and pop concerts by top international artists. Readings and recitals take place in the rotunda.
