taken from the on-site information board:
Since the Neolithic there are finds of megalithic tombs on Amrum. This grave site consisted of two burial chambers. The boulders lying in front of you belong to a burial chamber. It was uncovered in the 1950s. The second, which has already disappeared under the dunes today, was already robbed at the time.
Burial chamber 1
In the burial chamber several bones and skulls were discovered, which result from different burials. In addition, flintstone axes, arrowheads, richly ornamented ceramics and amber beads were found as grave goods.
Skull drill of the Stone Age
A skull had a so-called skull trepanning. A medical procedure in which the skullcap is opened with stone blades.
Trepanations were carried out, e.g. to treat skull bruises. Surprisingly, well over 50% of those affected survived the procedure. In this case, the nearly 30-year-old man did not survive the skull injury caused by a stone slash weapon despite surgery.
