On July 1, 1999, the last session of the parliament in Bonn took place in the plenary hall. The plenary hall has been open to the public as a congress center since autumn 1999. With its two building complexes, the plenary building and the main building, the World Conference Center Bonn offers capacities for events with up to 7,000 people. The size of the main halls can be adapted to the most varied of event concepts by means of partition walls, so Bonn’s congress center also offers tailor-made solutions for smaller events. Conference technology and ICT infrastructure meet the highest demands of customers from politics, business, science, associations and international organizations.
