The Bregenz Festspielhaus is an event center in Bregenz and was opened in July 1980. It is the venue for the Bregenz Festival and the venue for conferences, congresses, and events. The operator of the Congress culture Bregenz GmbH, a wholly-owned subsidiary of the state capital Bregenz is.

In 1990, architectural competition for an extension of the building was announced, which was won by the architects Helmut Dietrich and Much Untertrifaller, based in Bregenz and Vienna, with their architectural office of the same name, Dietrich/Untertrifaller. The concept envisaged a two-stage expansion of the existing building.

The first part of the extension was built in 1996/1997, including the workshop stage with side stage, lake studio, lake foyer, central kitchen, and the new administrative part of the house.

In 2005/2006, the existing building from 1980 was completely renovated and expanded by 10,000 cubic meters. The "Platz der Wiener Symphoniker" in front of the Festival and Congress Hall was redesigned as part of an "Art and Construction" project.

The approximately 7-meter high sculpture "Ready Maid" was created by Gottfried Bechtold. According to the renowned Vorarlberg artist, the inverted tree made of polished bronze is a striding tree woman, an antipode, a diametrically opposed art object to the performances. The sculpture stands in a slight depression, which, depending on the amount of precipitation, turns into a water-based paint and mirror surface up to 15 centimeters deep.

Cerith Wyn Evans created an installation of white neon light that reads "299,792,458 m/s" - the speed of light. The installation was mounted on the Festspielhaus and can be perceived as a light object itself, as a reflection in window panes and in the water, as shadows, etc.
The multifunctional orientation of the Festspielhaus now enables the implementation of a wide variety of event types. Conferences and congresses, cultural events, entertainment as well as company events, and social events form the portfolio of the house. In 2009 the Festspielhaus in Bregenz was voted one of the best event centers of its size in Europe by the European Association of Event Centers (EVVC) and received the corresponding award "Best Center 2009". In 2013, the Bregenz Festival Hall again received an award from the EVVC, this time in cooperation with the German Convention Bureau, namely the “Meeting Experts Green Award” in the “Sustainable Event Center” category.

In addition to the annual Bregenz Festival, performances of the Bregenz Spring Dance Festival, the Bregenz master concerts, concerts of the Vorarlberg Symphony Orchestra, and shows and concerts of all genres take place in the Festspielhaus.

At the Seebühne Stars like Falco, Peter Gabriel, Supertramp, Herbert Grönemeyer, Elton John, Udo Jürgens, Xavier Naidoo and Cro gave concerts. In 2008, film recordings of James Bond 007: a Quantum consolation were recorded there.
