An underground tunnel that archaeologists believe was meant to imitate the underworld has been found under a pyramid at Teotihuacan in Mexico. Electrical scans taken at the ancient city revealed the extent of the mysterious tunnel.
“The finding confirms that Teotihuacans reproduced the same pattern of tunnels associated with their great monuments, whose function had to be the emulation of the underworld,” archaeologist Veronica Ortega, who was involved in the discovery, said in a statement.
