The Bregenz Festival is an opera, music and theater festival that takes place annually in July and August in Bregenz, the capital of Vorarlberg in Austria.

The biggest attraction is the performance on the lake on the world's largest lake stage: usually an opera production, always together with the Vienna Symphony Orchestra, which makes the biggest contribution to the festival.

The festival is known for the beauty of the natural backdrop of Lake Constance, oversized stage sets, technical masterpieces and unique acoustics, which are achieved through the technique of so-called Bregenz directional hearing. In spring 2008, filming for the James Bond film Quantum of Solace also took place on the lake stage.

In 2024, the Bregenz Festival program comprised around 80 events, which were attended by around 269,000 spectators.

The festival became an international event in its very first year in 1946. People from Germany, Switzerland and France came to the festival. Two stages were built from floating barges. At the first festival, Mozart's Little Night Music, choreographed as a ballet, was performed as a “play on the lake”.

After a donation from Karl Deuring, the festival had the largest lake stage in the world from 1950 with a grandstand that could hold 6400 people and, after further extensions, could now hold almost 7000 spectators. Every year, a major musical theater production was staged as a play on the lake, initially mostly operettas, singspiels or play operas, and since the 1970s increasingly operas from the international repertoire and musicals. Since 1985, the productions have been performed on the lake stage for two years at a time.

In July 2021, a contract was signed for the renovation and expansion project in the festival district. Construction work on the project, which has a budget of 60 million euros, is scheduled to last until the summer of 2024, with the theater continuing to operate. The federal government will cover 40 percent of the costs, the state 35 percent and the city of Bregenz 25 percent, with the Festival having to raise the remaining 5.5 million euros itself. In addition to the renovation of the Festspielhaus and the grandstand, a multi-purpose building with workshops is to be built alongside the existing workshop stage. (Source: Wikipedia)
