The Internationales Congress Centrum Berlin (ICC Berlin), located in the Westend locality of the Berlin borough of Charlottenburg-Wilmersdorf, is one of the largest conference centres in the world. It is used for conventions, theatrical productions, and concerts.
ICC Berlin opened in 1979, and its architects were Ralf Schüler and Ursulina Schüler-Witte. It is 320 metres long, 80 metres wide and 40 metres high. As perhaps Europe's biggest such centre, it is instrumental to Berlin being one of the top congress cities in the world. It is serviced by S-Bahn station Berlin Messe Nord/ICC. By its own reckoning, ICC Berlin is a landmark of post-war German architecture and has served as an inspiration for similar facilities around the globe.
