Rothenbach Hall was built new in 2007, offering an impressive 5,700 m2 of floor space as the multifunctional hall for Kassel's Trade Fair. The functional space extends 10m in to the air, with no intruding beams or pillars. The hall is equipped to allow for a broad range of uses. Celebrations, concerts, sporting events, high-carat evening gathering and exhibitions of usual objects are all possible. Rothenbach Hall can be completely darkened, is outfitted with acoustic tiles on the walls for optimal sound and is designed for loads ranging from 300 kg to 2 t to be hung from the ceiling. It can hold up to 5,000 visitors. There is also a two-storey entry area with a large foyer, a congregation room and a number of side rooms, providing event organisers with the freedom to configure congresses, meetings and other events for up to 300 guests.
