Hundreds of mysterious spheres have been discovered beneath the Temple of the Feathered Serpent, in the pre-Hispanic city of Teotihuacan, just 30 miles from Mexico City

According to archaeologists from the Mexico National Institute of Anthropology and History, the spheres would have appeared to be made of gold because they are covered in jarosite - a bi-product of the oxidisation of pyrite, also known as Fool's Gold

Infrared scanners found the location of the chamber and the orbs. Archaeologists have no idea what the spheres would have been used for, although believe they may have been involved with religious rituals
