Tempelbergwarte, Observation tower on the Tempelberg in Sankt Andrä-Wördern, Austria

Tempelbergwarte is a 14.3-metre observation tower on the 403-metre Tempelberg between Altenberg and Hadersfeld in Sankt Andrä-Wördern. Its ground plan measures 4.9 by 5.9 metres. The upper platform at 13.2 metres is reached by 47 interior steps plus 13 steps of an iron stair from the lower platform at about 10.7 metres.

The tower was built in 1908 to honor Emperor Franz Joseph I after 60 years of his reign, with its inauguration on September 27 of that year. It suffered damage during World War II but was later restored through renovation efforts.

The tower was decided on 26 June 1906 by the Altenburg municipal council for Emperor Franz Joseph I's 60th jubilee, and the Wördern firm Karner built it from spring 1908. At the opening on 27 September 1908 the orthopaedist Adolf Lorenz gave the ceremonial speech.

The climb to the upper viewing platform at about 13 meters is achieved via the interior spiral staircase and is relatively short. From there, you can see across the flat landscape of the Tullnerfeld region and the course of the Danube River.

The tower was decided on 26 June 1906 by the Altenburg council for Emperor Franz Joseph I's 60-year reign jubilee, and the opening speech on 27 September 1908 was given by the orthopaedist Adolf Lorenz. The Klosterneuburg section of the Austrian Tourist Club later saved the dilapidated structure, reopening it on 7 October 1956 after subsidies of 16,000 schillings.
