Wartenberg, hill in the Magdeburger Börde near Calbe, Germany

Wartenberg is a 121-metre hill about four kilometres west of Calbe (Saale) in Saxony-Anhalt, the highest natural elevation in the southern Magdeburger Börde. It belongs to an end-moraine ridge separating the Elbe-Saale floodplain from the Börde. On its summit stands a round Bismarck tower, 30 metres high, built of Glöther limestone.

Bronze Age finds show the hill served Germanic tribes as a burial site and sanctuary. In the 19th century, sand and gravel quarrying on the eastern slope reshaped the terrain. A Wotan gate was rebuilt in October 2001 after the original was destroyed in the Second World War.

The area has long served as a walking destination for local people, with trails connecting nearby villages and settlements. These routes remain part of how residents experience and move through their landscape.

The Bismarckturm on the summit is open to visitors on weekends and public holidays; a spiral staircase of 157 steps leads to the upper platform. The hill lies about four kilometres west of Calbe, and a local animal park is part of the recreation area.

The Wotanstor gate on the summit was rebuilt in October 2001 after the original was destroyed in the Second World War; its oak lintel carries a head of the Germanic god Wotan carved by the Calbe sculptor Otto Plönnies.
