Stand on the Plaza of the Moon and watch the city come back to life around you: painted pyramids, a festival procession, and a city of 100,000 people stretching to the mountains.

Teotihuacán: The Avenue That Climbs to the Moon
The audio walk: 12 stops, about 3 h. Walk it, and see 450 CE at the stops where the past appears.
Walk around. On site, your phone's location moves you through the ancient city as you walk the plaza. Anywhere else, tap the ground to walk there.
Stand at the walk's stops. 6. Pyramid of the Sun, 7. Avenue of the Dead, 8. Palace of Quetzalpapalotl, 9. Patio of the Pillars, 10. Jaguars with conch shells, 11. Plaza of the Moon and 12. Pyramid of the Moon, each numbered as on the walk, plus the Moon platform.
Then and now. Hold your phone up on site and a time wave turns the view in front of you into the city in 450 CE. Tap a numbered stop or a small dot for what it was, what is there today and how we know.
The buildings follow their excavated footprints. Heights, painted designs, the festival and the people are our reconstruction from murals and excavation reports, not a record of a particular day.
Reconstruction by Roamer from OpenStreetMap footprints and published excavation reports; heights, colours and the festival are interpretive. Today: 360° photo by Fuzheado (Wikimedia Commons, CC0). An independent experience, not affiliated with INAH.
