Bronze Age Barrows (image) Faculty of Science - University of Copenhagen Share Print E-Mail Caption This image shows a typical group of Danish Bronze Age barrows from ca. 3,500-3,100 BP. Normally they were 3-5 meters high, constructed with cut out grass turfs (sods). One barrow would demand 3 hectares of grazing land. In Denmark 50,000 such barrows were constructed during the period 3,500- 3,100 BP for the leading chiefly lineages.
