A highly detailed map of the Galgenberg Traject. Thanks to a promovendi of the study Landscape History of the University of Groningen. You can see the lines of the Wheeltracks, the darker spot in the left is the Galgenberg. During the Middle Ages passengers were warned by a gallows on the tumulus.

The dark horizontal en vertical lines are the paths caused by the army. In the past the Ballooërveld was used as a military training aria.
