The Hanover Exhibition Center is the second largest in the world. After the Second World War, it developed into the most important location in Germany and replaced Leipzig. Deutsche Messe AG is one of the five major German trade fair organizers and is active in around 100 countries. The city of Hanover and the state of Lower Saxony each hold just under half of the shares. The company organizes around 150 trade fairs in Germany and abroad every year. Exhibitors have 26 halls with an area of 392,445 square meters at their disposal, supplemented by 58,000 square meters of outdoor space. The site also includes a congress center.
