Rujm el-Hiri is the largest ancient megalithic monument in the near east, located 16 kilometers east of the Sea of Galilee in the western part of the historic Bashan plain of the Golan Heights.

Archaeologists suggest it was constructed either during the Early Bronze Age II around 3000 to 2700 BC, or from the Chalcolithic–Early Bronze Age I between 3880– 3540 BC (although there is still no consensus).

It consists of a series of concentric circles that centres on a mound or cairn. The circles used approximately 37,500-40,000 tons of volcanic basalt material, stacked to a height of 2 metres, with a large oval shaped circle containing four progressively thinner rings. It might have functioned at least partially as an astronomical observatory.
