Stadttheater Baden is the town's historic main theatre, with roots going back to the early 18th century and a present building shaped by the Jugendstil era. It stages plays, musicals, and operettas, fitting Baden's long identity as a spa town with a serious music habit.
Even if you are not attending a performance, the building is worth noticing on a walk through the centre. Pair it with Beethoven House, Kurpark, and the Sommerarena for a good sense of Baden's cultural life.
