The Grosser Saal, which seats up to 1,079 people, with its pronounced colour scheme and striped seat covers that have long been something of a trademark, is unique. Together with its fly tower it also forms the outwardly visible architectural core of the building. The space with its excellent sight lines and outstanding acoustics as well as a fully equipped stage is conceived to be equally suited to performances of concerts, dance and music. Its multiple uses range from a proscenium theatre to an arena to a ballroom.
