Richat Structure

The Richat Structure is a prominent geological formation in the Adrar region northwest of Ouadane. It is often used as a frame of reference for astronauts in orbit.

**Unveiling the Enigma of : The “Eye of the Sahara”**

In the heart of Mauritania lies a geological marvel that has puzzled scientists and mesmerized observers for centuries—the Richat Structure. Commonly referred to as the “Eye of the Sahara” due to its distinctive circular shape, this natural wonder is a captivating blend of mystery and geological splendor.

**Formation and Characteristics:**

The Richat Structure, located near the town of Ouadane, is a massive and deeply eroded geological dome spanning approximately 40 kilometers in diameter. What makes it particularly intriguing is its concentric ring pattern, resembling a colossal bull’s-eye when viewed from above.

Scientists believe that the RichatRichat Structure was formed over millions of years through a combination of geological processes, including uplift, erosion, and the subsequent collapse of a volcanic dome. The resulting concentric rings are composed of different rock layers, each telling a story of the Earth’s dynamic history.

**The Geographical Enigma:**

One of the enduring mysteries surrounding the Richat Structure is its true origin. Initially mistaken for an impact crater, further research has dispelled this theory. Unlike traditional impact craters, the Richat Structure lacks the central peak and shock-metamorphic rocks typically associated with such formations.

As scientists delve deeper into the structure’s geological history, the Richat continues to offer insights into the Earth’s past climates and the processes that shaped its surface. Its unique appearance has even led to its inclusion in astronaut training, as the circular feature is easily visible from space.

**Astronomical Alignment:**

Adding to the intrigue, some researchers suggest that the Richat Structure may have astronomical significance. The alignment of certain features with cardinal directions and celestial phenomena has sparked theories about ancient cultures potentially using the site for astronomical observations or rituals.

**Visitor Experience:**

For those drawn to geological wonders, a visit to this place is a journey into the Earth’s geological timeline. Travelers can explore the structure’s outer rings, observing the diverse rock formations and capturing the breathtaking panoramic views of the surrounding Mauritanian landscape.

**Preserving a Geological Heritage:**
Recognizing the Richat Structure’s scientific and aesthetic value, conservation efforts are underway to protect this geological treasure. Visitors are encouraged to engage in responsible tourism practices, ensuring that future generations can continue to marvel at the “Eye of the Sahara.”


In conclusion, the Richat Structure stands as a geological enigma, inviting scientists, adventurers, and curious minds to unravel its mysteries. Whether viewed from the vantage point of space or explored on the ground, this natural wonder continues to captivate all who encounter its circular allure in the heart of the Mauritanian desert.

Oualata (or Walata) is one of the cornerstone trade cities in the trans-Saharan Trade Route. It is now an UNESCO World Heritage Site, and one of the farthest of the ancient Mauritanian cities to reach from Nouakchott. Traveling to this city requires passing through Tichit, so it can almost always be seen together with another of the four ancient cities. You’ll also pass awesome sites on the way as well, like the Elephant Mountains. It is rich with history as a cultural and religious center as the southern terminus of the centuries-old trade route, and, fittingly, the home of a manuscript museum.
