The Temple of Kukulcan, a large pyramid also known as the Castillo, is the main temple in Mayapan. It is located immediately to the east of the Cenote Ch'en Mul, which has caves radiating from it. In form, the Temple of Kukulcan (Structure Q-162 on the site map) is a radial four-staircase temple with nine terraces; it is generally similar to the Temple of Kukulcan at the earlier site of Chichen Itza. However, the Mayapan temple appears to be an inferior imitation of the one at Chichen Itza, and the city's buildings in general are not constructed as well as those in other Mayan cities. For example, most or all of the vaulted roofs in Mayapan have collapsed, while many of the better-built buildings at Chichen Itza remain intact. Other major temples in the ceremonial center include three round ones, which are unusual for the Maya area and are also linked to the deity Kukulkan/Quetzalcoatl in his wind god (Ehecatl) aspect. Unlike Chichen Itza, Mayapan has no ballcourts.
