First mentioned in 1297 when it served as the chapel of a Dominican abbey, the monastery and church were closed during the Reformation in 1523. The building was used for a time as the city's armoury, until it was taken over by a Lutheran congregation in 1582. During the building's construction two monks were bricked into the southern wall and lived out their lives there, fed through the window grate. In the summer months organ and vocal music concerts are held here every Saturday at 17:00, which are open to the public.
