The Florianturm is the TV tower of Dortmund and was built in 1959 as an attraction for a federal horticultural show with a height of 219.6 metres. At the time it was briefly the highest freestanding structure in Germany.
The tower was constructed similarly to a high concrete chimney. It consists of a reinforced concrete tube, which tapers off as it rises, reaching a height of 129.75 metres. At 130.6 metres there is a building part with two floors. On the lower floor there are operation rooms and on the upper floor at 137.54 metres there is a revolving restaurant. At 141.88 metres and 144.7 metres there are two observation decks.
On the upper observation deck there are installations and aerials of Deutsche Telekom . Since 1959 it has been used for transmitting television signals.
On September 7, 2004, a Russian helicopter was used to replace the aerial. Since then, a 50-kilowatt transmitter has transmitted digital terrestrial television programmes for the Dortmund area.
Since September 7th, 2004 the Florianturm has a height of 211.36 metres. making it the fourteenth highest structure in Germany.
From 1996 to 1998 the tower was renovated and safety standards were brought up to date.
In 2000 a catwalk for bungee-jumping was opened on the upper platform. It was closed in 2003 after a fatal accident but has not yet been uninstalled.
