The museum presents the life and works of Johann Sebastian Bach and his family in an interactive multimedia exhibition covering an area of 750 square metres. One of the highlights is the treasure room, where original Bach manuscripts and other precious items are on display. Prize exhibits include the console of an organ inspected and approved by Bach himself in 1743 from the erstwhile St John's Church, a casket containing relics from Bach’s tomb, and a recently discovered cash box once owned by the Bach family. Furthermore, the pleasance, the audio room and the Gloria café are all great places to relax after a busy time in the museum.
