One of these is a 1,000-year-old gold dinar struck in 453 AH, and uncovered by an archaeologist at King Saud University, local media reported.
The gold dinar, an Islamic medieval gold coin, was found only 20 centimeters below the surface at the archaeological site.
A new astronomical phenomenon linked to the Rajajil site was also found, in addition to six other Fatimid coins, glass bottles with writings dating back to the reign of the Caliph Al-Mustansir, part of a red agate pottery, and decorative beads.
Rajajil, often called the Stonehenge of Saudi Arabia, is a mysterious ancient site located on a sandstone terrace some 20 kilometers south of the center of Sakakah, the capital of Al-Jouf province, and a few kilometers south of Qarah village.
Archaeological excavations had revealed that Rajajil is indeed a burial site, but its true importance is “probably its role in the transition of lifestyles from nomadism toward sedentarism induced by climate changes on the Arabian Peninsula.
Archaeological investigation in the Al-Hajjar area also revealed the existence of 17 tombs with the names of 14 sculptors who worked in Madain Saleh, the first world heritage site of Saudi Arabia. The archaeological tombs in the area bore artistic inscriptions.
