If you’re after a show while in the centre of Bayreuth, you might want to get tickets at Margrave's Opera House. If you enjoy the show and want to see another, Festspielhaus and Oberfrankenhalle are both a short walk away.
Bayreuth New Palace is just one of the places to see in Bayreuth, so why not enjoy the other things to explore during your travels? Take in the festivals while you're in the area.
