The Haus des Rundfunks ("House of Broadcasting"), located in the Westend district of Berlin, Germany, is the oldest self-contained broadcasting house in the World. It was designed by Hans Poelzig in 1929 after winning an architectural competition. The building vis-à-vis the Funkturm contains three large broadcasting rooms located in the centre, shielded from street noise by the surrounding office wings. It is now used by the local ARD broadcaster Rundfunk Berlin-Brandenburg (RBB) and produces radio programs for the channels radioBerlin, Kulturradio, and Inforadio. The building's broadcasting rooms are occasionally also used to host concerts.
