During the leading industry fairs a lot of long distance trains of the "DB" as well as local trains of the "Metronom" and "Erixx" stop at the train station Hannover Messe/Laatzen.
Innovations for the whole world
466,100 square meters of covered indoor space, 58,000 square meters of open-air space, 26 halls and pavilions: that will give you an idea of just how big the home base of Deutsche Messe is - it's the biggest Exhibition Center in the world. Apart from the distinct architecture of the Exhibition Center's halls, it boasts a number of other features, including the Convention Center with its 35 function rooms, glassed-in areas between halls, grassy park-like areas and "chill-out" zones, to guarantee a relaxed yet productive atmosphere. The Hannover Exhibition Center sets worldwide standards in terms of its technical facilities, exhibition hall architecture and planning security for events of all shapes and sizes.
The exhibition grounds can be reached by car, as well as by two mass transit rail lines (terminating at the northern and eastern perimeters of the grounds) and the showground's own railway station, "Hannover Messe/Laatzen", which is located on Germany's heavily traveled North/South rail axis, connecting Hannover with Frankfurt and Hamburg.
Two pedestrian "skywalks" (i.e. covered, moving walkways) connect the railway station on the western side of the exhibition grounds with the entrance of Hall 13, and, on the eastern side, the parking lots with halls 8 and 9. A new tram line provides a fast and convenient connection between Hannover Airport, Hannover Central Railway Station and the exhibition site. Vehicular access roads to the exhibition site were designed to handle peak traffic volumes. Highways up to six lanes wide lead straight to the showground.
