Raimund Theater is one of Vienna's long-running musical stages, opened in 1893 for German folk plays and later adapted for operetta and large musical productions. The building is not as famous as the State Opera or the Burgtheater, but it gives Mariahilf a useful cultural stop for travellers interested in Vienna's popular theatre tradition.
Check the current programme before going; the main reason to visit is to see a performance rather than to tour the building.
