Mexico

The pre-Columbian Mayan city of Chichén Itzá is visited by over 1.2 million people annually (making it one of Mexico’s most-visited archaeological sites).

Not far from Tulum’s ruins, Cobá was a pre-Columbian Mayan city. At its peak, it is said to have housed over 50,000 people. The site’s tallest pyramid is 138 feet in height.

The origins of this Mesoamerican city are cloudy, but it’s postulated that it reached a population of over 150,000 at its peak. It not only houses the Pyramid of the Moon and Pyramid of the Sun, but residential compounds and the Avenue of the Dead as well.

Tulum is another pre-Columbian Maya site, known to be one of the last cities built by the Maya. The well-preserved walled city’s most famous buildings are El Castillo, the Temple of the Descending God, and the Temple of the Frescoes.
