The discovery of a secret tunnel in Mexico may finally solve some mysteries of the ancient city of Teotihuacán.
Running around 100 meters long and 15 meters deep, the underground passage led archaeologists to over 75,000 significant artifacts including pottery, rubber balls and evidence of a sacred ritual space.
A place that once served as a cosmopolitan centre of Mesoamerica, Teotihuacán is a city that archaeologists still know little about compared to other ancient civilizations.
The excavation project led by Mexican archaeologist Sergio Gómez, sheds light on what life was like in the pre-Aztec city . . .
