Bregenz
If you want to go a little further afield, go to Bregenz where the summer opera festival, the Bregenzer Festspiele, is a must. A different opera is performed every year on a floating stage and the standard is very high to compete with the thrilling natural scenery. Foto-Copyright: Bregenzer Festspiele / Karl Forster

St. Gallen
Lastly, if you want to go to a special place of worldwide renown, take a trip of about one hundred kilometres into Switzerland. St. Gallen has a beautiful historic centre where the famous cathedral and the old convent with its legendary library are to be found.
