Český rozhlas headquarters, Official residence and broadcasting headquarters in Vinohrady, Czech Republic

The Český rozhlas headquarters at Vinohradská 12 is a corner functionalist building designed by Bohumil Sláma and built from 1929 to 1931. Its steel skeleton, made in the Vítkovice ironworks, weighs 1,160 tonnes and was assembled in three and a half months. The structure forms a slightly irregular square about 60 metres on each side, composed of horizontal and vertical prisms on a base of two projecting window bands.

The building was completed in 1933 and represents modern architecture of the interwar period. It became significant in 1945 when civilians defended it against Nazi forces during the Prague Uprising, turning it into a symbol of resistance.

The building's name is tied to its role as the seat of Czechoslovak, then Czech Radio. On 5 May 1945 staff began broadcasting only in Czech and played banned Czech songs, which set off the Prague Uprising; the station called on listeners to come to its aid. In August 1968 it aired uncensored reports on the Warsaw Pact invasion and urged calm and quiet resistance.

The building stands on the corner of Vinohradská and Balbínova streets in Vinohrady, Prague 2. The nearest metro is line A at Náměstí Míru, a short walk away, and tram stops on Vinohradská třída serve the block. The main entrance faces Vinohradská; the newer studio buildings stand opposite in Římská street.

The steel frame, made in the Vítkovice ironworks, weighed 1,160 tonnes and took three and a half months to erect. During the Prague Uprising, staff removed German signs inside the building, so the 90 Waffen SS soldiers sent to seize it wandered the corridors disoriented.
