The '''Florianturm''' (Florian Tower, ''Florian'' for short) is a telecommunications tower and landmark of [[Dortmund]] ([[Germany]]). It is named after St. Florian, the [[patron saint]] of [[gardener]]s.

The Florianturm is the [[TV tower]] of Dortmund and was built in 1959 as an attraction for a federal [[horticulture|horticultural]] show with a height of {{convert|219.6|m}}. 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 {{convert|129.75|m}}. At {{convert|130.6|m}} there is a building part with two floors. On the lower floor there are operation rooms and on the upper floor at {{convert|137.54|m}} there is a [[revolving restaurant]]. At {{convert|141.88|m}} and {{convert|144.7|m}} there are two observation decks.

On the upper observation deck there are installations and [[Antenna (radio)|aerial]]s of ''[[Deutsche Telekom]]''. Since 1959 it has been used for transmitting television signals.

On 7 September 2004, a [[Russia]]n [[helicopter]] was used to replace the aerial. Since then, a 50-kilowatt transmitter has transmitted [[digital terrestrial television]] programmes for the Dortmund area.

Since 7 September 2004, the Florianturm has a height of {{convert|208.56|m}}, 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 and was removed in July 2008. [[File:Dortmund_-_PW-Konrad-Zuse-Straße_+_Florianturm_01_ies.jpg|thumb|A view of the Florianturm in 2012]]
