On 22 January 1931 the Haus des Rundfunks ("House of Broadcasting"), on Masurenallee in Berlin-Westend, was inaugurated as the official seat of the Reichs-Rundfunk-Gesellschaft. Designed in 1929 by the architect Hans Poelzig (1869-1936), it is the world's first self-contained broadcasting centre and includes a large concert hall.
