Europe's largest congress centre offers two large halls and around 80 smaller halls and rooms - and yet it is considered too small, too uneconomical in terms of room layout, too expensive in terms of operating costs - and to make matters worse, it is contaminated with asbestos. After long discussions about demolition and new construction, the ICC was supposed to be completely renovated and freed from asbestos in 2019. Since then, the ICC has been waiting for the renovation to start. Moreover, the future use of the building has not yet been decided. The building has been under monumental protection since September 2019.
