Bungsberg telecommunications tower

The Bungsberg telecommunications tower, also known as the Fernmeldeturm Schönwalde, is a 179-metre-high telecommunications tower situated on the Bungsberg, a hill which (at 168 metres above mean sea level) is the highest point in the north German state of Schleswig-Holstein. The tower, which belongs to Deutsche Telekom, is used for directional radio links, FM radio and television transmissions (see the list of frequencies below) and mobile telephony services. Constructed of concrete, weighing some 6000 tonnes, and having a diameter at its base of 8.4 metres, the tower is equipped with a public observation deck at a height of 40 metres, accessible by an internal staircase. The telecommunications tower was not the first tower incorporating a viewing platform to be erected on the Bungsberg. An 18-metre-high observation tower, the Elisabethenturm, had been built earlier, in 1861. This tower, extended to a height of 22 metres in 1864, is still standing, although closed to the public since the opening of the telecommunications tower.
