Richat Structure

Address
وادان, Mauritania

Deep within the vast expanse of the Sahara Desert in Mauritania lies a truly remarkable sight – the Richat Structure, often referred to as the “Ojo de la Sahara” or “Eye of the Sahara.” This colossal circular formation, approximately 40 kilometers in diameter, has captivated observers for decades, even appearing as a distinct feature in satellite imagery. Initially, it was mistakenly believed to be a meteorite impact, but scientific investigation has revealed a far more intriguing story: a symmetrical uplift – a dome of rock – that has been sculpted over millennia by wind and water erosion, revealing the layered bands within.

The colours are mesmerizing, ranging from deep browns to sandy yellows, creating a complex, concentric pattern that speaks volumes about the Earth’s geological history. Each ring represents a different period, offering a visual timeline of the region’s evolution. It’s a powerful reminder of the immense forces that shape our planet. To fully appreciate its scale and beauty, consider visiting a vantage point – a small rise or hill – to gain a panoramic perspective. Getting there typically involves travelling by autocarro (bus) or 4x4 vehicle from nearby towns, offering a taste of Mauritanian life. While there aren’t extensive facilities immediately surrounding the structure, the experience of witnessing this otherworldly formation is an unforgettable one. Don’t forget your telemóvel for navigation and to share your incredible discovery!

This was one of the main things we wanted to see while traveling around Mauritania- and it did not disappoint! We were able to go all the way to the center, thanks to Zaïda (owner of Auberge Vasque) who drove us there. Witnessing an otherworldly landscape like this and having it all to ourselves was truly special. I also recommend reading about Richat before going as it enhances the experience (just like anything else). Enjoy!

This is a must if you are in oudane. It’s less than 1 h drive. The view point is very wind but very cool to be in such location. Wear sneakers to be more comfortable. Best if you have a drone!!

Fascinating place. There is still a lot of debate about how was formed. Another reviewer here said this is a phenomenon from separating continents. But the rocks do not appear to be magmic; they are composite rocks, very strange and alluring. It's the kind of place where you feel like a major discovery of some kind could be made at any moment. Be warned, I was here in early October and it was over 40°C which is typical for the desert here, but the radiating heat refracting from the rocks made me feel like I was partially cooked alive later that day (because I was). The heat is stronger here than normal desert sand. We had a soundtrack of a crying goat who was about to be slain at a campsite in the center of the structure belonging to some gold prospectors. It's a testament that, along with most parts of Mauritania, you never know what to expect. This is a public site and is not maintained or managed by anyone. You can stop by some vendors on the outer ring of the structure who sell unique relics they've found on the grounds if you're disinclined to search for anything yourself.

Visiting the Richat Structure in Mauritania was truly an amazing experience. This natural phenomenon, sometimes referred to as the "Eye of Africa" for its characteristic circular shape, is one of the most intriguing geological formations in the world. Looking at the Richat Structure, you feel like a tiny speck compared to the vast scale of this natural beauty. Its immense diameter and distinctive circular shape are awe-inspiring.

The Richat Structure, also known as the "Eye of the Sahara," is a massive, circular geological formation located in the Sahara Desert in Mauritania. It is approximately 40 kilometers (25 miles) in diameter and can be easily seen from space, resembling a giant eye. The structure is believed to have formed as a result of volcanic activity and subsequent erosion. The Richat Structure is a unique and fascinating geological feature that has puzzled scientists for many years. While its exact origin is still debated, it remains a valuable source of information about the Earth's history. Eye of the Sahara.
