RIYADH — The Saudi Heritage Authority announced the registration and documentation of 13 archeological sites in four regions — Riyadh, Qassim, Tabuk and Al-Jouf — in the second quarter of 2021. The sites will be added to the list of the national register in its latest update, which includes a number of historical archaeological sites representing a significant historical heritage of Saudi Arabia. The Authority also seeks to register them in the National Antiquities Register and digital maps so that they can be managed, protected, and preserved effectively. The registered sites are represented in a number of stone structures, various tools, inscriptions, rock and art paintings that date back from the post-Neolithic period, fragments of green-glazed pottery dating back from the early Islamic period, and stone objects from the late Acholian period. Of all registered sites, the largest share of sites registered was from the Qassim region with six sites. Riyadh and Tabuk regions come second with three sites in each region, and followed by Al-Jouf with two registered sites. Overall, the Authority had registered 642 archaeological sites during the first quarter of this year, bringing the total number of discovered archeological sites to 8,176 sites.
