Consisting of four concentric stone walls surrounding a large heap of stones that covers a massive dolmen (pictured here, two vertical stone slabs supporting an upper horizontal slab), the megalithic complex of Rogem Hiri in the Golan has long puzzled archaeologists. Some have speculated that the complex originally functioned as an ancient astronomical observatory, while others have suggested it served as a sanctuary or funerary site for the Chalcolithic and Bronze Age populations of the Golan.
