Haselbergturm, Wooden observation tower in Königsbrück, Germany.

Haselbergturm is a 34-metre wooden observation tower built in 2008 on the Haselberg in the Königsbrücker Heide nature reserve. It has nine storeys linked by a galvanised steel staircase and two viewing platforms at heights of 13 and 32 metres. Its foundation consists of 150 cubic metres of reinforced concrete.

The tower was built in 2008 on land that served as a military training ground from 1906 to 1992. After the military period ended, the area became open to the public.

The tower stands on the Haselberg, formerly called Wettinhöhe, a name that recalls the Saxon Wettin dynasty. Its opening on 10 May 2008 was celebrated as a public event, turning a former military training ground into an accessible lookout point.

The tower's nine levels are linked by a galvanized steel staircase with 156 steps, leading to platforms at 13 and 32 meters. The Haselberg summit stands at 190 meters above sea level, and the tower's foundation consists of 150 cubic meters of reinforced concrete.

The tower stands on the Haselberg, a hill 190 metres above sea level that was formerly called Wettinhöhe. Its foundation alone required 150 cubic metres of reinforced concrete, poured before the timber frame was raised in 2008.
