The 38-meter tall structure is enclosed with an open-air cage allowing screened views of the encompassing nature reserve.
It takes its name from the Z-shaped design that resembles a lightning bolt.
The steel structure is 22 meters high.
The tower is 16.5 meters tall with a viewing platform at the top that can be rotated.
It offers visitors a magnificent view over one of the last raised bogs in Europe.
The tower is built in the shape of a seven and integrated into the environment.
The10-storey helix-shaped structure replaced a dreary, 40-year-old steel and concrete tower in 2013.
The tower was designed by Jorg Schlaich, using cable-stayed bridge technology, and erected in 2000.
The lookout tower was opened to public in July 1998.
Inside, a spiral staircase winds up to an observation deck.
