These stone circles have existed for thousands of years, but only in 1920 they were noticed for the first time. They were noticed during an airplane flight over Jordan.
Archaeologists have given them the graceful name “Big Circles”. They are so huge that it is difficult to determine where they start and where end! The only chance to see them entirely is the airplane flight. They are located in different countries of The Middle East. Most of them are located in Jordan, Syria and Saudi Arabia. The researchers say that they arose for the same reason, but it is not clear what were the reasons for their construction.
