In 1957 the Nationaltheater was the first new building to be constructed in Mannheim after the end of the Second World War. With over 350 000 spectators per season in each of the two main venues — the 1 156-seat opera and 639-seat theatre — the NTM is one of the most important cultural institutions in the city. Listed building.
This striking modernist building is now a cultural monument and over five years will be completely renovated and expanded. Both venues will be fully refurbished while enhancing the room acoustics and simultaneously preserving their historic character. A large orchestra rehearsal hall, choir rehearsal hall, recording studio and multiple music practice rooms will be added in the new 3 500 m² basement extension. Kahle Acoustics is providing specialist room acoustics consultancy for the musical and performance spaces, in collaboration with the main project acousticians EGS-Plan (Stuttgart).
