“The discoveries were made on a nondescript side street just behind the city’s colonial-era Roman Catholic cathedral off the main Zocalo plaza on the grounds of a 1950s-era hotel. The underground excavations reveal a section of what was the foundation of a massive, circular-shaped temple dedicated to the Aztec wind god Ehecatl and a smaller part of a ritual ball court, confirming accounts of the first Spanish chroniclers to visit the Aztec imperial capital, Tenochtitlan.”
