the term landesbühne (federal state stage) or "landestheater" (federal state theatre) is added to the name of some publicly owned theatre companies in germany and austria. these companies have a mandate to perform in areas without public theatres. less than half of performances usually take place at the seat of a landesbühne, thereby distinguishing them from the so called "stadttheater" (city theatre) or "staatstheater" (national theatre). legal control can lie with the respective bundesland or a collaboration of several municipalities and local authorities. the spectrum of presented productions can be very diverse. the repertoire can include all or parts of the popular disciplines: play, musical theatre (opera, operetta, musical), ballet, and children's and youth theatre.
