It consists of an archive, a museum and a library. Regular events for theatre enthusiasts take place on the in-house studio stage, whereby the young audience is also especially addressed. Guest performances at the Theatre museum include children's theatre performances, narrative theatre performances and improvisational performances. Until recently, the theatre museum was housed in the Hofgärtnerhaus in the Hofgarten, in future it will be centrally located in the former post office building at the main station.
