Researchers discovered tunnels beneath an archaeological site near Mexico City's Mexican capital, apparently dedicated to worshiping characters from the "underworld."
The details of the discovery, described by the experts as "spectacular," were presented in a statement by researchers at the National Institute of Anthropology and History of Mexico, the Sun newspaper reported.
Veronica Ortega, director of the integrated conservation project on Piazza de la Luna, the central square of the complex where the tunnels were discovered, said the excavations focused on a ritual space associated with the "underworld."
The investigation of the tunnels will enable them to identify the relationship between this old city and other areas of Central America.
The discovery of the tunnels is due to a preliminary study using the so-called "electrical resistance", conducted around the "Moon Pyramid" in June 2017.
The method of "electrical resistance" is a form of geophysical survey, which helps to create a picture of sub-surface layers.
This method uses variations in electrical potentials to identify sub-surface materials.
The tunnels, believed to have been dedicated to religious rites, are 26 feet below the moon's pyramid and are 49 feet in diameter.
The Pyramid of the Moon, the second largest pyramid in Mexico after the pyramid of the sun, scientists believe that the structures of these pyramids were established before 200 AD.
