Festspielhaus Baden-Baden, Opera house and concert hall in Baden-Baden, Germany

The Festspielhaus Baden-Baden is a modern opera and concert venue in Baden-Baden with seating for around 2,500 people. The building features specially designed acoustics and technical systems optimized for orchestral performances.

The Festspielhaus opened on 18 April 1998 in a new building by Viennese architect Wilhelm Holzbauer, integrated with the former Baden-Baden central railway station built in 1904. That station had replaced an 1845 terminus and closed with its branch line in 1977. After public start-up funding, the house became Europe's first privately financed opera and concert company.

Since 2022 the season follows the calendar year, structured by seven festivals: Takeover in February, the Berlin Philharmonic's Easter festival, Presence with the SWR Symphony Orchestra at Pentecost, La Capitale d'Été in July, The World of John Neumeier in October, the German-French festival La Grande Gare in November and the Winter Festival at Christmas. The house has no ensemble of its own; internationally renowned artists are engaged, and the foyer of the former station serves as box office and restaurant.

The former railway station section now holds the box office, the Aida restaurant and the Toccarion children's music world, so these are entered through the old station building. The 2,500-seat hall itself sits in Holzbauer's new structure alongside it. The house runs seven festivals across the calendar year, from Takeover in February to the Winterfestspiele at Christmas, with single events in between.

The old station building, erected in 1904, now holds the box office, the Aida restaurant and the Toccarion children's music world, while the 1998 hall by Wilhelm Holzbauer stands beside it. The branch line it served, opened in 1845, closed in 1977. The house has no ensemble of its own; a private foundation funds the programme, and around 2,000 donors give about eight million euros a year.
