Archaeological sites A cluster of Abbasid-period (750–1253) archaeological sites are found near the north-west coast and include Ar Rakiyat, Umm Al Kilab, Ghaf Makin, Mussaykah, Murwab, and Al-Haddiyah. Structures that were excavated at these sites were roughly aligned with Mecca. All of the sites are situated next to rawdas (depressions), ensuring a reliable water supply.
