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 gardeners. It 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. (Text based on Wikipedia).
