18. The Stone Circles of Jordan
The Stone Circles, also simply known as ‘The Big Circles’, are 12 giant circular structures made with stones that are located in Jordan as well as Syria. Despite them being over 2000 years ago, very little is actually known about them.
Each circle is almost 1000 to 1500 feet across and built with low height stone walls made with local stones, that would’ve not been especially difficult to build. However, we still don’t know why they were built, especially in near-perfect circles.
