The Kuppelsaal is part of the HCC (Hannover Congress Centrum).
The town hall with the domed hall was built from 1911-1914 by Paul Bonatz. Even after the opening of the Elbphilharmonie in Hamburg, the Kuppelsaal is still the largest classical concert hall in Germany with 3,642 seats. Together with further 6 halls, 4 halls and 30 rooms the Kuppelsaal forms the HCC. Directly behind the Stadthalle is the garden "Stadtpark".
