Used between the 16th and 19th centuries, this road was used to transport silver extracted from the mines of Zacatecas, Guanajuato and San Luis Potosí, as well as mercury imported from Europe.

The Mayan town of Uxmal, in Yucatán, was founded c. A.D. 700 and had some 25,000 inhabitants. The layout of the buildings, which date from between 700 and 1000, reveals a knowledge of astronomy.

The cultural landscape of the Prehistoric Caves of Yagul and Mitla demonstrates the link between man and nature that gave origin to the domestication of plants in North America, thus allowing the rise of Mesoamerican civilizations.
