THE SECRET CAVE LIES HIDDEN BELOW THE ENORMOUS 'MOON PYRAMID'
JULY 5, 2020
A secret cave hidden underneath a Mexican pyramid offers clues about the urban design of Teotihuacan, one of the largest and most vibrant cities of ancient times.
Located about 80 kilometers outside of todays Mexico City, Teotihuacan peaked in AD 300650, well before the Aztecs. The city boasted three monumental pyramids arranged along the 2.4-kilometer Street of the Dead.
Two of the pyramids were already known to overlie caves and tunnels, which were excavated by Teotihuacanos to obtain construction materials, and were later repurposed for activities such as astronomical observations, the veneration of death and the enthronement of rulers.
Denisse Argote at the National Institute of Anthropology and History in Mexico City and her colleagues measured the electrical resistance of the ground beneath the third structure, the 43-meter-high Moon Pyramid.
They discovered a partially filled cavern about 15 meters underneath the edifice.
