The three-storey Hall 4 has a direct link to the Congress Center Basel located above it. It thus has the ideal infrastructure configuration for trade fairs/accompanying exhibitions and congresses. Not only can Hall 4 be used independently, as a self-contained venue, it is also especially suited to fairs where specialist events are held in parallel, as well as for conferences with accompanying exhibitions. A walkway links Hall 4 to Hall 1 and the Event Hall
on the ground floor. Furthermore, eleven modular meeting rooms
were being created in the exhibition space in Hall 4, on the ground floor of the Congress Center Basel.
