AlUla, in northwestern Saudi Arabia, is a land of extraordinary natural beauty and deep history. For thousands of years, its famed oasis, framed by dramatic sandstone mountains, has sustained diverse flora, fauna, and thriving human communities. What makes AlUla truly unique is its geological legacy, showcasing three distinct eras of Earth’s past. The oldest formations, the Precambrian Arabian Shield rocks, are layered with sediments deposited over millions of years. These layers preserve a permanent record of ancient environments, including fossilised plants and animals, offering remarkable insights into Earth’s evolution while shaping AlUla’s breathtaking and timeless desert landscape.
