This mysterious structure lives in the Israeli-occupied part of Golan Heights, Levant. Made up of over 42,000 basalt rocks, it creates a giant wheel that can be seen from space. It dates back to the Early Bronze Age II period, which is roughly 3000-2700 BCE. In the centre is a burial mound, but there are no human remains inside.

Archeologists figure that it took over 70 years to build and there’s nothing else like it anywhere in the world, to any guesses to what it is and what it means, is pure speculation.
