Each summer, in the middle of an enchanting landscape in the westernmost Austrian federal state of Vorarlberg, the Bregenz Festival presents high-calibre opera al fresco with the theatre on the lake. In addition, the festival attracts approximately 200,000 visitors to the border triangle between the Alps and Lake Constance with unforgettable debut opera performances and concertante treasures in the Festival House, unheard material as part of “Kunst aus der Zeit” at the studio theatre, as well as touching gems of operatic literature at the Theater am Kornmarkt in the months of July and August, with more than 80 performances in total.
