According
http://www.tagesspiegel.de/berlin/Br...art128,2651817 to the second tallest structure in Berlin, Berlin Frohnau directional radio mast (
http://skyscraperpage.com/cities/?buildingID=8946 ) will soon be demolished. It is 358.5 metres tall and was completed in 1979. Until German reunification it was used for a radio relay link to Gartow in Lower Saxony. What it was exactly used for after 1990 is unclear, as it was never used for broadcasting.
The mast is a very stable structure equipped with a cabinet for technical equipment on the top, which may be the highest-elevated cabinet on a manmade structure in the European Union!
