At the heart of the fascination is the most visited and the most spectacular of Late Classic Maya cities: Chichén Itzá. Chichén Itzá was inhabited for hundreds of years and was a very influential center in the later years of Maya civilization. At its height, Chichén Itzá may have had over 30,000 inhabitants, and with a spectacular pyramid, enormous ball court, observatory and several temples, the builders of this city exceeded even those at Uxmal in developing the use of columns and exterior relief decoration. Of particular interest at Chichén Itzá is the sacred cenote, a sinkhole was a focus for Maya rituals around water. Because adequate supplies of water, which rarely collected on the surface of the limestone based Yucatan, were essential for adequate agricultural production, the Maya here considered it of primary importance. Underwater archaeology carried out in the cenote at Chichén Itzá revealed that offerings to the Maya rain deity Chaac (which may have included people) were tossed into the sinkhole. Early Mayapán was closely connected to the overshadowing power of the region at the time: the mighty trading city of Chichén Itzá. Mayapán emerged first as a minor settlement in the orbit of Chichén, but it slowly came to replace it after the larger city's trade connections with the Toltecs of Tula crumbled and it suffered a staggering defeat by Mayapán's armies. The building styles and art in their city show both admiring references to the great Chichén Itzá as well as an attempt to position Mayapán as a more orthodox heir of Maya tradition. At the same time, they emulated many features and could not escape the tremendous influences - especially in religion - of Chichén. This is seen in the fact that many of the most important buildings in the new city appear to be small-scale reproductions of ones in Chichén. The Maya maintained power in the Yucatan for over a thousand years, and at the height of its "Classical era" (3rd-9th centuries CE), the city of Tikal was one of the power centers of the empire. Archaeologists believe Tikal had been built as early as the 5th or 4th century BC, and eventually it became a political, economic and military capital that was an important part of a far-flung network across Mesoamerica, despite the fact it was seemingly conquered by Teotihuacan in the 4th century CE. It seems the foreign rulers came to assimilate Mayan culture, thus ensuring Tikal would continue to be a power base, and as a result, the city would not be abandoned until about the 10th century CE. During the Maya's Classical era, the city of Uxmal was one of its most noteworthy places. While it was not as powerful as cities like Tikal, Uxmal was apparently at the forefront of Mayan culture, particularly when it came to architecture. However, while Uxmal used high ground to display its prominence, and the ruins are still among the most popular places for tourists in the region, the site is still shrouded in mystery. Even as scholars continue to work on the site to further interpret it, it's still unclear when exactly Uxmal was founded, how many people called it home, and when it was abandoned, despite the existence of Mayan chronicles and oral legends. What is apparent, however, is the skills of Uxmal's artisans, whether through constructing structures like the five-level Pyramid of Magicians and the expansive Governor's Palace or adorning the structures with precisely detailed art and sculptures. In fact, the craftsmanship can be credited with helping to preserve Uxmal itself.
