Archaeological Zone of Paquimé, Casas Grandes

Paquimé, Casas Grandes, which reached its apogee in the 14th and 15th centuries, played a key role in trade and cultural contacts between the Pueblo culture of the south-western United States and northern Mexico and the more advanced civilizations of Mesoamerica. The extensive remains, only part of which have been excavated, are clear evidence of the vitality of a culture which was perfectly adapted to its physical and economic environment, but which suddenly vanished at the time of the Spanish Conquest.

The Archeological Zone of Paquimé, Casas Grandes is a pre-Columbian archaelogical site.

It began as a group of 20 or more house clusters, each with a plaza and enclosing wall. These single-story adobe dwellings shared a common water system. Evidence shows that Paquimé had a complex water control system that included underground drain systems, reservoirs, channels for water to get to the homes, and a sewage system

Pre-Hispanic Town of Uxmal

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 Pyramid of the Soothsayer, as the Spaniards called it, dominates the ceremonial centre, which has well-designed buildings decorated with a profusion of symbolic motifs and sculptures depicting Chaac, the god of rain. The ceremonial sites of Uxmal, Kabah, Labna and Sayil are considered the high points of Mayan art and architecture.

Pre-Hispanic City of Chichen-Itza

This sacred site was one of the greatest Mayan centres of the Yucatán peninsula. Throughout its nearly 1,000-year history, different peoples have left their mark on the city. The Maya and Toltec vision of the world and the universe is revealed in their stone monuments and artistic works. The fusion of Mayan construction techniques with new elements from central Mexico make Chichen-Itza one of the most important examples of the Mayan-Toltec civilization in Yucatán. Several buildings have survived, such as the Warriors’ Temple, El Castillo and the circular observatory known as El Caracol.

The Pre-Hispanic City of Chichen-Itza is a large archaeological site built by the Maya civilization. It is located in the northern center of the Yucatán Peninsula, present-day Mexico. It is one of the most important examples of the Mayan-Toltec civilization in Yucatán.

Chichen Itza was a major regional center in the northern Maya lowlands from the Late Classic through the Terminal Classic and into the early portion of the Early Postclassic period. The site exhibits a multitude of architectural styles, from what is called “Mexicanized” and reminiscent of styles seen in central Mexico to the Puuc style found among the Puuc Maya of the northern lowlands. The presence of central Mexican styles was once thought to have been representative of direct migration or even conquest from central Mexico, but most contemporary interpretations view the presence of these non-Maya styles more as the result of cultural diffusion.

Archaeological data, such as evidence of burning at a number of important structures and architectural complexes, suggest that Chichen Itza's collapse was violent. Following the decline of Chichen Itza's hegemony, regional power in the Yucatán shifted to a new center at Mayapan.
