12 Iconic Landscapes Only Found in Africa's Remote Corners

3. Richat Structure (Eye of the Sahara), Mauritania: Africa’s Giant Spiral

Visible from orbit and enigmatic even on the ground, Mauritania’s Richat Structure—nicknamed the Eye of the Sahara—is a geological marvel like no other. This vast, circular formation spans nearly 30 miles across, comprised of concentric rings of rock unfolding in the desert. Scientists believe the structure formed through an ancient uplift and erosion process, though elements of its origins remain mysterious. Bedouin stories swirl around the Eye, attributing mystical powers or ancient civilizations to its spiral patterns. Its stark isolation, deep in the Saharan wilderness, adds to its allure. There are no roads leading directly here; most adventurers rely on experienced guides and sturdy vehicles to navigate the sand seas. Images captured from space often spark curiosity among aspiring explorers, but standing at its rim, visitors experience an overwhelming sense of scale and wonder. Richat’s haunting symmetry has inspired both scientists and storytellers alike.
