This three-storey complex was completed in 2013 as an extension to Hall 1 that had opened back in 1999. Access is from the North and South Foyers in the City Lounge, with its striking atrium. The hall is also linked to the Congress Center Basel via a raised walkway, has a unique inscription system with a 112 m-long LED light band and complies with Minergie Standard BS-054. Exhibitions with multi-storey stands, events that require stage and platform structures, and other major occasions are just a few of the countless options that can be accommodated in this unique building designed by star architects Herzog & de Meuron.
