The Richat Structure, Oudane, Mauritania, is not really a structure but a huge circular formation (50 km in diameter - 30 miles), that resembles an eye when looked upon from space.

Surprisingly, there is a hotel smack in the middle of the Richat Structure. It's nothing luxurious, but it offers adequate accommodations for "Mad Max" style tourists
