A professor of archaeology at the University of Oxford discovered around 400 mysterious stone structures on and around volcanoes in Saudi Arabia.

David Kennedy found the structures, using Google Maps, in the western Harrat Khaybar region. The walls could be more than 9,000 years old—which would make them older than the famous Peruvian Nazca lines—according to The Independent.
