Megalithic tomb “Dellbrücker Kammer”
Tomb from the younger Stone Age (extended dolmen); built around 2700 BC.
The site, which is now completely free-standing, was previously covered by a heaped up hill. The chamber is structurally intact. The stone circle that surrounds the monument today is probably modern.
The builders of such graves belonged to the so-called funnel beaker culture. It was the first farming population in Schleswig-Holstein to practice agriculture and animal husbandry. They buried their deads in burial chambers made of mighty stones (large stone graves or megalithic graves).
