When does 
 a program become an event?

From conferences 
to corporate events. 

The main building adapts to your event—not the other way around. From corporate events to conferences with up to 3,730 attendees: versatile halls, modern digital infrastructure, and maximum flexibility for events of any size. The main building is also directly connected to the plenary building via the underground Rhine passage, making it easy to combine both venues for larger events.

Together, we’ll find the combination that’s right for you.
