Visible throughout most of the city, this television antenna is actually located in the former East Berlin, and if nothing else, it's immensely useful as a landmark from which to get your bearings.

Built in 1969, the Fernsehturm is still the second tallest structure in Europe, and is nicknamed Telespargel ('toothpick') by locals. Certainly, from the ground, it is a remarkable structure, and well worth a look. Several buildings in the area around the base of the structure hold the studios of TVB – Berlin's own television channel.

Supposedly, it's possible to get a lift up to the metal sphere, 203 metres above the ground, however, when I was there, the area was shrouded with fencing, and the tower was most decidedly closed to visitors.

A friend of mine has visited the tower when it's open, and tells me that the view is quite remarkable, allowing incomparable views out over the city and the surrounding area, when the weather's good. He also told me that it's pretty cheap, and that there's a revolving café in the metal sphere which revolves once every half an hour.

Obviously then, if the place is actually open, it's definitely worth going in, though queues can apparently be long, so it would probably be best to get there early!
