Stone 30

A megalith is a large stone used to build a prehistoric structure or monument, either alone or with other stones. More than 35,000 megalithic structures have been identified in Europe, from Sweden in the north to the Mediterranean in the south, and megaliths are found worldwide. The word was first used in 1849 by the British antiquarian Algernon Herbert for Stonehenge, and comes from the Greek for "great stone". Most extant megaliths were erected between the Neolithic, with some earlier Mesolithic examples, and the Bronze Age. The oldest known ceremonial structures in the world, Göbekli Tepe and Nevalı Çori in Turkey, are dated to about 9000 BCE. Further down this page, About this kind of monument gives the whole of “Megalith (type not specified)”.

Typological estimate, not a date for this site: monuments of this kind in this region are normally dated 3470 BCE to 2760 BCE. The range comes from what is known about megalith monuments in Kingdom of the Netherlands; nothing measured on this site itself is on record, so it may be younger or older than the range suggests.

The range rests on this regional background (source: the Wikipedia article “Megaliths in the Netherlands”): Dutch hunebedden were built between 3470 and 3250 BC and were used until about 2760 BC.
