History and description

Old tower

Historical recordings

The first observation tower on the Kahlenberg was a 16 m high, listed steel lattice tower built in 1911 . The tower was donated by Otto Stein, an industrialist from Kirchen (Sieg). The construction costs amounted to 2000  gold marks . After the first donation of 1000 marks, which was not enough for the construction costs, Otto Stein decided to take over the remaining costs. In 1912 the tower was named "Ottoturm" in his honor.

Because of its steel construction, it was supposed to be demolished and melted down during World War II to meet the shortage of iron and steel. The population resisted this plan and was able to prevent the destruction.

Since the tower was made of rust-prone Thomasstahl , structural defects increasingly occurred over the years, so that the tower could no longer be climbed since the spring of 2006 due to its ailing condition. In December 2006 the “Friends of the Otto Tower” association was founded in Herkersdorf, which campaigned for its reconstruction even before the tower was demolished. The old tower, for which renovation was ruled out due to the nature of the steel, was demolished in May 2009.

New tower

From June 17, 2010, a new observation tower, also called the Ottoturm, was built at the same location. The Friends' Association took on more than half of the total cost of 120,000 euros, with an amount of over 50,000 euros for the stairs alone, all of which were donated with sponsorship.

The tower is 18.59 m. high. A left-hand metal staircase leads over 102 steps and 15 intermediate platforms to the viewing platform at a height of 17.34 m. Four orientation boards are attached to the parapet.

Opportunities for viewing

The Ottoturm provides a panoramic view of parts of the Siegerland, the view of the Giebelberg and the Siegtal - including the Siegtalbrücke of the A 45 and parts of Siegen in the northeast, Betzdorf in the southwest, Kirchen in the west and Herkersdorf in the south.
