The distinctive baroque vaulted ceiling in the second basement of Mozarthaus Vienna has been converted with great architectural sensitivity that perfectly combines the old and the new into a remarkable multipurpose event venue. Thanks to its outstanding acoustics it is regularly used for chamber music concerts and CD recordings. 

A variable stage area and conference technology with sound and lighting systems make it ideal for business events, presentations and lectures. 

The event room also offers a unique setting for Christmas parties and private functions like weddings and birthdays. The room was renamed BÖSENDORFER HALL in MOZARTHAUS VIENNA in 2010 as part of a cooperation with Bösendorfer pianos. Mozarthaus Vienna and Bösendorfer together offer a varied concert programme.
