Side of the Temple of Kukulkan and the Great Ball Court in the distance in Chichen Itza (Mexico).
Dominating the North Platform of Chichen Itza is the Temple of Kukulkan (a Maya feathered serpent deity similar to the Aztec Quetzalcoatl), usually referred to as El Castillo (“the castle”). This step pyramid stands about 30 metres (98 ft) high and consists of a series of nine square terraces, each approximately 2.57 metres (8.4 ft) high, with a 6-metre (20 ft) high temple upon the summit. The sides of the pyramid are approximately 55.3 metres (181 ft) at the base and rise at an angle of 53°, although that varies slightly for each side. The four faces of the pyramid have protruding stairways that rise at an angle of 45°. The talud walls of each terrace slant at an angle of between 72° and 74°. At the base of the balustrades of the northeastern staircase are carved heads of a serpent.
Archaeologists have identified thirteen ballcourts for playing the Mesoamerican ballgame in Chichen Itza, but the Great Ball Court about 150 metres to the north-west of the Castillo is by far the most impressive. It is the largest and best preserved ball court in ancient Mesoamerica. It measures 168 by 70 metres. The parallel platforms flanking the main playing area are each 95 metres long. The walls of these platforms stand 8 metres high; set high up in the centre of each of these walls are rings carved with intertwined feathered 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; the wound emits streams of blood in the form of wriggling snakes.
At one end of the Great Ball Court is the North Temple, also known as the Temple of the Bearded Man (Templo del Hombre Barbado). 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 the 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.
In the entrance to the Lower Temple of the Jaguar, which opens behind the ball court, is another Jaguar throne, similar to the one in the inner temple of El Castillo, except that it is well worn and missing paint or other decoration. The outer columns and the walls inside the temple are covered with elaborate bas-relief carvings.
