Other tall structures

Europaturm - The Europe Tower is a telecommunication tower known as the Frankfurt TV Tower. It is the tallest tower in the city with a height of 337.5 metres. It was open to the public until 1999, with an entertainment establishment in the revolving top. It is normally referred to by the locals as "Ginnheimer Spargel" (The Ginnheimer Asparagus) which is not correct because it is not located in the Ginnheim district but stands a few metres within the Bockenheim district.
Henninger Turm - The Henninger Tower is a 120-metre high grain silo built from 1959-1961 and owned by Henninger Brewery. It has two rotating restaurants at the height of 101 and 106 metres and an open-air observation deck at the height of 110 metres. The tower has been closed to the public since October 2002. Plans to destroy the tower and replace it were abandoned. Today there are new plans to convert it into a residential tower.
Goetheturm - The Goethe Tower is a 43-metre high tower built entirely out of wood on the northern edge of the Frankfurt City Forest in Sachsenhausen. It is the fifth tallest wooden construction in Germany. It was built in 1931 and is still a popular place for day-trippers, especially families, as a large playground and a café have been built at the foot of the tower.
