It is located on the ancient caravan route linking the eastern Mediterranean and the Najd plateau. This serial property consists of two desert sites where there are Jabal Umm Sinman in Jubbah and the mountains of Al-Manjour and Rata in Shuwaymis. As for the series of heights of Umm Sinman, it overlooks a lake of fresh water, of which no trace remains at the present time. It provided water for people and animals in the southern part of the Great Nafud Desert. The ancestors of the current Arab populations have left traces of their presence in many petroglyphs and many other inscriptions. The mountains of Al-Manjour and Rata form the rocky slopes of a valley covered with sand at the present time, which represents a large number of human and animal forms, dating back to 10,000.
