With a capacity of 2,500 seats, the Festival Hall Baden-Baden is one of the largest classical music venues in Europe. The building features a unique architecture as the opera hall sits on the trackbed of a former railway station, whose neo-classicist structure serves as the entrance hall of the Festival Hall Baden-Baden. The reconstructed opera house was designed by the Viennese architect Wilhelm Holzbauer in the mid-1990’s in accordance with ideal acoustic values calculated by the acclaimed Munich-based physicist Karlheinz Müller.
