Gauss Tower, Observation tower and transmitter on Hoher Hagen summit, Germany.

Gauss Tower is an observation and transmission tower on the summit of the Hoher Hagen, in the Göttingen district of Germany. The concrete structure stands 51 meters tall with a cylindrical shaft, and it carries both a viewing platform and a restaurant at the top.

The tower opened in September 1964 after around eleven months of construction, built to provide modern transmission equipment at this elevation. At the same time, it was designed to welcome the public, combining technical infrastructure with an accessible hilltop destination.

The tower is named after Carl Friedrich Gauss, who used this hill as a survey point for his geodetic work across the Kingdom of Hanover. From the viewing platform today, visitors look out over the same rolling terrain that Gauss once mapped from the ground.

The lift holds up to eight people and takes 55 seconds to reach the top. The emergency stairway has 225 steps from the viewing platform down to the entrance or cellar. The upper platform is open only by arrangement with the Dransfeld Verschönerungsverein, and the restaurant has been closed since 2012.

The tower that stands today is the second on this spot: the original 1911 Gaußturm, built from basalt, cracked as quarrying crept beneath it and collapsed in 1963. A court ruling obliged the basalt works to fund a replacement, and the concrete tower was finished in September 1964 after eleven months of work. Its nickname in the 1970s was "widerliche Koch-Röhre", after the quarry's manager Klaus Koch.
