The Berliner Funkturm or Funkturm Berlin (Radio Tower Berlin) is a transmitting tower in Berlin, built between 1924 and 1926 by Heinrich Straumer. It is nicknamed "der lange Lulatsch" ("the lanky lad") and is one of the best-known points of interest in the city of Berlin. It stands in the Berlin fairground in the Charlottenburg Wilmersdorf district. On September 3, 1926, the radio tower was inaugurated on the occasion of the 3. Große Deutsche Funkausstellung (third Great German radio exhibition). The tower is now a protected monument.
