Taken from the on-site information board:
During the Bronze Age (2nd millennium BCE), burial mounds were constructed from turf, earth or stones as tombs for a single individual. Initially, burials in wooden coffins were carried out in such mounds. Later, after religious beliefs had evidently changed and cremation had become widespread from the Middle Bronze Age onwards, the charred skeletal remains were initially scattered in the space originally intended for the wooden coffin within the mound, and later urn burials were carried out.
It is not uncommon to find secondary burials in such mounds, some of which took place much later. Originally, the majority of megalithic tombs (also known as giant’s tombs) were also located in or beneath mounds. Burial mounds were often clustered together. Like the megalithic tombs, they were defining features of the Mecklenburg landscape until the introduction of land consolidation. They served as landmarks for travellers and as boundary markers for the local population.
