The Great Hall (797 seats) is the most sought-after concert hall in the region. With its excellent acoustics (reverberation time approx. 1.7 sec), it is equally suitable for solo recitals, chamber music, symphony and choral concerts as well as for big band and pop music events.

Among other things, the "Master Concerts" of the "Musical Academy" take place here, a series with top interpreters of the international classical music scene. Since 2016, the hall organ of the company Orgelbau Klais, equipped with the latest technology, has been sounding in this representative hall.
