In its original form, the Galgenberg is neither a gallows nor a mountain, but an extensive burial ground. The time range has been proven to be from 5000 BC to around 700, 800 AD.
Around 800 AD, the burial mound was raised to form a fortified hill, probably with a wooden tower or a fortified castle, which at the time was mostly no more than a palisade ring wall. There was also a dry ditch and a rampart all around.
Around 1695, the place of execution was moved from its traditional location on the Amtmannweide in the outer dike to the approximately 20-meter-high "Koppelberg", which now had to lose its old name, first popularly and later officially, in favor of the martial name "Galgenberg".
