Varus tower, Observation tower in Georgsmarienhütte, Germany.

The Varus Tower is a 21-metre-high reinforced concrete observation tower on the Lammersbrink, at the southern edge of Georgsmarienhütte in Lower Saxony. It was built in 1975 by the construction firm Carl Möller for the town, replacing an 1892 viewing tower on the same spot that was blown up in August 1935 because it had become unsafe. Its identical twin, the Hermannsturm, stands on the neighbouring Dörenberg to the southeast.

The first observation tower on the Lammersbrink was erected in 1892 by the Georgsmarien-Verein AG and had to be demolished by blasting in August 1935 because it was dilapidated. The present 21-metre reinforced concrete tower was built in 1975 by the construction firm Carl Möller on behalf of the town of Georgsmarienhütte. It is named after the Roman commander Varus, who suffered a crushing defeat by Arminius in the Battle of the Teutoburg Forest in 9 AD. After a routine inspection on 4 October 2016, the tower was classified as dilapidated and remained closed until October 2021.

The tower is named after the Roman commander Varus, defeated by Arminius at the Battle of the Teutoburg Forest in 9 AD. Its identical twin, the Hermannsturm on the neighbouring Dörenberg, is named after Arminius; the Kammweg trail links the two and forms part of the roughly 100 km Ahornweg.

The tower is accessible via marked walking paths that connect different sections of the surrounding area. These trails are well-maintained and easy to follow for visitors exploring the landscape.

The Varus Tower has a twin: the Hermannsturm on the neighbouring Dörenberg to the southeast was built to the same design. A ridge path, the Kammweg, links the two towers and forms part of the roughly 100 km Ahornweg long-distance trail.
