Like a giant target, when seen from the air, the stone circles of Rujum el-Hiri form one of the oddest structures on the Golan. A solid, circular, stone cairn stands more than 20 feet high at the center of the site, which covers an area about 500 feet in diameter. Three concentric circles of stone walls, now largely tumbled down, surround the cairn (see close-up). Speculations about the site’s purpose include the suggestions that it was used for astronomical calculations or for an elaborate burial. The mystery will probably remain until archaeological excavations take place at the site.
