22 Lost Cities Underwater, On Land, and in Legend

North of Mexico City stretches an avenue once called “the Road of the Dead.” Teotihuacan’s pyramids rise along it, immense and silent, built by people whose names are lost. The Aztecs later found the ruins and revered them, adding myths to the mystery. Climbing the Pyramid of the Sun now, you see how carefully the city aligns with stars and cardinal points.

Archaeologists still debate who its builders were, but everyone who visits agrees: geometry has rarely felt so alive and perfect.
