Which UNESCO World Heritage Site in Mexico preserves the ancient city of Teotihuacan and its Pyramid of the Sun?

The UNESCO World Heritage Site in Mexico preserving the ancient city of Teotihuacan and its Pyramid of the Sun is the Pre-Hispanic City of Teotihuacan.

Teotihuacan developed northeast of present-day Mexico City and became one of the largest cities in the ancient Americas. Its monumental core includes the Avenue of the Dead, the Pyramid of the Sun, the Pyramid of the Moon, and the Temple of the Feathered Serpent. The city flourished during the first half of the first millennium AD and influenced political and artistic traditions far beyond central Mexico.

The people who built Teotihuacan are not securely identified, and the city’s original name is unknown; “Teotihuacan” is a Nahuatl name used later by the Aztecs. It is therefore not an Aztec-built city. UNESCO inscribed the Pre-Hispanic City of Teotihuacan in 1987.
