The Berliner Fernsehturm or Fernsehturm Berlin is a television tower in central Berlin, Germany.
Located in the Marien quarter, close to Alexanderplatz in the locality and district of Mitte, the tower was constructed between 1965 and 1969 by the government of the German Democratic Republic. It was intended to be both a symbol of Communist power and of the city. It remains a landmark today, visible throughout the central and some suburban districts of Berlin. With its height of 368 metres it is the tallest structure in Germany, and the third-tallest structure in the European Union. When built it was the fourth-tallest freestanding structure in the world after the Ostankino Tower, the Empire State Building and 875 North Michigan Avenue, then known as The John Hancock Center.
Of the four tallest structures in Europe, it is 2 m shorter than the Torreta de Guardamar, 0.5 m shorter than the Riga Radio and TV Tower, and 8 m taller than the Trbovlje Power Station in 2017. The structure is also more than 220 metres higher than the old Berlin Radio Tower in the western part of the city, which was built in the 1920s.
