Saudi Arabia’s Heritage Commission estimates there could be over a million archaeological sites in the country, including petroglyphs, rock art, and stone structures along the Red Sea and Arabian Gulf coasts. Currently, more than 3,500 archaeological sites are registered in the Kingdom. Among these, over 1,000 sites in the Red Sea hold remnants of submerged cultural heritage, like shipwrecks and cargoes dating back over 1,600 years.
