Stone Age grave Denghoog

Megalithic tombs are collective graves that have been used repeatedly and over a very long period of time. Nearly 50 megalithic tombs are known on Sylt, eight of which are fully or partially preserved. The Denghoog is one of the most impressive and best-preserved megalithic tombs of the Neolithic period in Germany. Within the large earth mound is a completely preserved stone chamber with six massive capstones. Be impressed by the size of the chamber, which is elliptically shaped and measures five meters east-west and three meters north-south. 

Denghoog means "hill with an underground chamber" or "hill in the meadow," as it stood completely free in the landscape just 100 years ago. In Sylt-Frisian (Sölring), it is called Thinghügel, which translates as "assembly hill."

During the Middle Neolithic, in the Funnel Beaker culture period, massive megalithic tombs were built over a short period of approximately 600 years. These tombs, still impressive today, are partly made of enormous boulders. 
The bodies of the dead were buried in these graves. The graves were often still in use during the subsequent Bronze Age. The shape of the graves evolved from simple rectangular stone chambers to dolmens, polygonal chambers, and passage graves. The passage facilitated subsequent burials. The graves were covered with earth and had the shape of round or long mounds.

It is disputed whether the dead were buried directly in the graves or whether only the bones were deposited later.
