El Castillo
Main article: El Castillo, Chichen Itza
Dominating the center of Chichén is the Temple of Kukulcan (the Maya name for Quetzalcoatl), often referred to as "El Castillo" (the castle). This step pyramid with a ground plan of square terraces with stairways up each of the 4 sides to the temple on top. On the Spring and Fall equinox, at the rising and setting of the sun, the corner of the structure casts a shadow in the shape of a plumed serpent - Kukulcan, or Quetzalcoatl - along the side of the North staircase. On these two days, the shadows from the corner tiers slither down the northern side of the pyramid with the sun's movement.
Mesoamerican cultures periodically built larger pyramids atop older ones, and this is one such example. In the mid 1930s, the Mexican government sponsored an excavation into El Castillo. After several false starts, they discovered a staircase under the north side of the pyramid. By digging from the top, they found another temple buried below the current one. Inside the temple chamber was a Chac Mool statue and a throne in the shape of jaguar, painted red with spots made of inlaid jade.
The Mexican government excavated a tunnel from the base of the north staircase, up the earlier pyramid’s stairway to the hidden temple, and opened it to tourists. In 2006, INAH closed the throne room to the public.
Temple of the Warriors
The Temple of the Warriors complex consists of a large stepped pyramid fronted and flanked by rows of carved columns depicting warriors. This complex is analogous to Temple B at the Toltec capital of Tula, and indicates some form of cultural contact between the two regions. The one at Chichen Itza, however, was constructed on a larger scale. At the top of the stairway on the pyramid’s summit (and leading towards the entrance of the pyramid’s temple) is a Chac Mool.
Near the Warriors is a large plaza surrounded by pillars called "The Great Market."
The Great Ball Court
Archaeologists have identified seven courts for playing the Mesoamerican ballgame in Chichén, but the Great Ball Court about 150 meters to the north-west of the Castillo is by far the most impressive. It is the largest ball court in ancient Mesoamerica. It measures 166 by 68 meters (545 by 232 feet). The imposing walls are 12 meters high, and in the center, high up on each of the long walls, are rings carved with intertwining serpents.
At the base of the high interior walls are slanted benches with sculpted panels of teams of ball players. In one panel, one of the players has been decapitated and from the wound emits seven streams of blood; six become wriggling serpents and the center becomes a winding plant.
At one end of the Great Ball Court is the North Temple, popularly called the Temple of the Bearded Man. This small masonry building has detailed bas relief carving on the inner walls, including a center figure that has carving under his chin that resembles facial hair. At the south end is another, much bigger temple, but in ruins.
Built into east wall are the Temples of the Jaguar. The Upper Temple of the Jaguar overlooks the ball court and has an entrance guarded by two, large columns carved in the familiar feathered serpent motif. Inside there is a large mural, much destroyed, which depicts a battle scene.
