The Oldest Buildings in the World

19. Cuicuilco Circular Pyramid (800-600 BC), Mexico

Although the concept of pyramids is associated with Ancient Egypt, these majestic structures can also be found in Mexico.

Thought to have been built in stages between 800 and 600 BC, the structure is also one of the first works in which the solar calendar was used for the first time.

Cuicuilco, which can be visited as an archaeological site today, is the right address for those who wonder how Mesoamerican civilizations were born.
