Chichen Itza was one of the largest Maya cities, with the relatively densely clustered
architecture of the site core covering an area of at least . Smaller scale residential architecture extends for an unknown distance beyond this. Archeologists have identified over 80
sacbeob criss-crossing the site, and extending in all directions from the city. Many of these stone buildings were originally painted in red, green, blue and purple colors. Pigments were chosen according to what was most easily available in the area. The site must be imagined as a colorful one, not like it is today. Just like Gothic cathedrals in Europe, colors provided a greater sense of completeness and contributed greatly to the symbolic impact of the buildings. The architecture encompasses a number of styles, including the Puuc and Chenes styles of the northern Yucatán Peninsula. The Puuc-style building feature the usual mosaic-decorated upper façades characteristic of the style but differ from the architecture of the Puuc heartland in their block masonry walls, as opposed to the fine veneers of the Puuc region proper. At least one structure in the Las Monjas Group features an ornate façade and masked doorway that are typical examples of Chenes-style architecture, a style centered upon a region in the north of the state of
Campeche, lying between the Puuc and
Río Bec regions. Those structures with sculpted hieroglyphic script are concentrated in certain areas of the site, with the most important being the Las Monjas group.
Architectural groups Great North Platform Temple of Kukulcán (El Castillo) Dominating the North Platform of Chichen Itza is the
Temple of Kukulcán (a Maya
feathered serpent deity similar to the Aztec
Quetzalcoatl). The temple was identified by the first Spaniards to see it, as
El Castillo ("the castle"), and it regularly is referred to as such. This
step pyramid stands about high and consists of a series of nine square terraces, each approximately high, with a high temple upon the summit. The sides of the pyramid are approximately at the base and rise at an angle of 53°, although that varies slightly for each side. Mesoamerican cultures periodically superimposed larger structures over older ones, and the Temple of Kukulcán is one such example. In the mid-1930s, the Mexican government sponsored an excavation of the temple. 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 and with spots made of inlaid jade. Around the
Spring and
Autumn equinoxes, in the late afternoon, the northwest corner of the pyramid casts a series of triangular shadows against the western balustrade on the north side that evokes the appearance of a serpent wriggling down the staircase, which some scholars have suggested is a representation of the feathered-serpent deity, Kukulcán. It is a widespread belief that this light-and-shadow effect was achieved on purpose to record the equinoxes, but the idea is highly unlikely: it has been shown that the phenomenon can be observed, without major changes, during several weeks around the equinoxes, making it impossible to determine any date by observing this effect alone. Recent 3D modeling and multimodal scanning in 2025 has revealed an earlier pyramid substructure, deemed "Castillo-sub," that is enclosed within the larger "El Castillo" pyramid structure. High-resolution digital mapping demonstrated that the construction of Castillo-sub occurred earlier than El Castillo, and through a different architectural process. Castillo-sub was determined to have been built over the course of several successive stages of building enlargement, rather than one construction project during a single point in time. This sequentual process of progressive, layered construction aligns with other common Mesoamerican architectural strategies, where new rulers would expand pre-existing sacred buildings.
Great Ball Court Archeologists have identified in Chichen Itza thirteen
ballcourts for playing the
Mesoamerican ballgame, but the Great Ball Court about to the north-west of the Castillo is the most impressive. It is the largest and best preserved ball court in ancient Mesoamerica. It measures . The parallel platforms flanking the main playing area are each long. 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.
Additional structures The
tzompantli, or
Skull Platform (
Plataforma de los Cráneos), shows the clear cultural influence of the central
Mexican Plateau. Unlike the
tzompantli of the highlands, however, the skulls were impaled vertically rather than horizontally as at
Tenochtitlan. The
Platform of the Eagles and the Jaguars (
Plataforma de Águilas y Jaguares) is immediately to the east of the Great Ballcourt. It is built in a combination Maya and
Toltec styles, with a staircase ascending each of its four sides. The sides are decorated with panels depicting eagles and jaguars consuming human hearts. This
Platform of Venus is dedicated to the planet
Venus. In its interior archeologists discovered a collection of large cones carved out of stone, the purpose of which is unknown. This platform is located north of El Castillo, between it and the Cenote Sagrado. The
Temple of the Tables is the northernmost temple among a series of buildings to the east of El Castillo, to its north lies an area of columns. Its name comes from a series of altars at the top of the structure that are supported by small carved figures of men with upraised arms, called "atlantes." The
Steam Bath is a unique building with three parts: a waiting gallery, a water bath, and a steam chamber that operated by means of heated stones.
Sacbe Number One is a causeway that leads to the Cenote Sagrado, is the largest and most elaborate at Chichen Itza. This "white road" is long with an average width of . It begins at a low wall a few meters from the Platform of Venus. According to archeologists there once was an extensive building with columns at the beginning of the road.
Sacred Cenote The
Yucatán Peninsula is a
limestone plain, with no rivers or streams. The region is pockmarked with natural
sinkholes, called cenotes, which expose the
water table to the surface. One of the most impressive of these is the Cenote Sagrado, which is in diameter and surrounded by sheer cliffs that drop to the water table some below. The Cenote Sagrado was a place of pilgrimage for ancient Maya people who, according to ethnohistoric sources, would conduct sacrifices during times of drought. Archeological investigations support this as thousands of objects have been removed from the bottom of the cenote, including material such as gold, carved jade, copal, pottery, flint,
obsidian, shell, wood, rubber, cloth, as well as skeletons of children, men, and women. Offerings of artifacts and human remains have been found within the Sacred Cenote. However, the nature of how and why these were found in the cenote is unclear. Not all skeletons in the cenote displayed signs of trauma; some may have been deliberate non-violent burials. Some Spanish sources, which describe Maya sacrifices into the cenote, were written a significant time after the classic Maya period during which these supposed acts occurred, and they might have colonial biases. Whether the human remains in this cenote are evidence of sacrificial behavior is still a subject of ongoing debate.
Bioarchaeological and Genetic Evidence Recent bioarchaeological and archaeogenetic research has led to new insights into the ritual practices that occurred at Chichen Itza. In 2024, a genome-wide association study (GWAS) analyzed the bodily remains of 64 individuals who were discovered in a ceremonial context, a finding which was dated back to approximately 500-900 CE. All of the discovered individuals were determined to be male, as well as two sets of monozygotic twins. Comparing these individuals genetically, they were determined to be strongly related to current Maya populations. The majority of genetic variation between these individuals and modern Maya people was found at immunity-related genetic loci. Archaeologists interpret this discovery as potential evidence for the careful selection of certain individuals for ritualistic sacrifices, perhaps following a cultural pattern.
Chultun of Children In 1967, while building an airstrip 200 meters north of the Cenote Sagrado, workers found a small cave system that contained the remains of more than 100 children, a majority between the ages of three and six. DNA testing in the 2020s found that the remains exclusively came from males. Archaeologists have concluded that because the remains came from individuals of a narrow range of age and sex, and that DNA testing found some were related (including two pairs of identical twins), the remains had been part of a"ritual event." Although the remains show no evidence of sacrifice, some researchers believe that may have been part of the ritual.
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 toward the entrance of the pyramid's temple) is a Chac Mool. This temple encases or entombs a former structure called The Temple of the Chac Mool. The archeological expedition and restoration of this building was done by the
Carnegie Institution of Washington from 1925 to 1928. A key member of this restoration was
Earl H. Morris, who published the work from this expedition in two volumes entitled
Temple of the Warriors. Watercolors were made of murals in the Temple of the Warriors that were deteriorating rapidly following exposure to the elements after enduring for centuries in the protected enclosures being discovered. Many depict battle scenes and some even have tantalizing images that lend themselves to speculation and debate by prominent Maya scholars, such as
Michael D. Coe and
Mary Miller, regarding possible contact with Viking sailors.
Group of a Thousand Columns Along the south wall of the Temple of Warriors are a series of what are today exposed columns, although when the city was inhabited these would have supported an extensive roof system. The columns are in three distinct sections: A west group, that extends the lines of the front of the Temple of Warriors. A north group runs along the south wall of the Temple of Warriors and contains pillars with carvings of soldiers in bas-relief; A northeast group, which apparently formed a small temple at the southeast corner of the Temple of Warriors, contains a rectangular decorated with carvings of people or gods, as well as animals and serpents. The northeast column temple also covers a small marvel of engineering, a channel that funnels all the rainwater from the complex some away to a rejollada, a former cenote. To the south of the Group of a Thousand Columns is a group of three, smaller, interconnected buildings. The
Temple of the Carved Columns is a small elegant building that consists of a front gallery with an inner corridor that leads to an altar with a Chac Mool. There are also numerous columns with rich, bas-relief carvings of some 40 personages. A section of the upper façade with a motif of x's and o's is displayed in front of the structure. The
Temple of the Small Tables which is an unrestored mound. And the '''Thompson's Temple
(referred to in some sources as Palace of Ahau Balam Kauil'
), a small building with two levels that has friezes depicting Jaguars (balam'' in Maya) as well as glyphs of the Maya god Kahuil.
El Mercado This square structure anchors the southern end of the Temple of Warriors complex. It is so named for the shelf of stone that surrounds a large gallery and patio that early explorers theorized was used to display wares as in a marketplace. Today, archeologists believe that its purpose was more ceremonial than commercial.
Osario Group South of the North Group is a smaller platform that has many important structures, several of which appear to be oriented toward the second largest cenote at Chichen Itza, Xtoloc.
The Osario itself, like the Temple of Kukulkan, is a step-pyramid temple dominating its platform, only on a smaller scale. Like its larger neighbor, it has four sides with staircases on each side. There is a temple on top, but unlike Kukulkan, at the center is an opening into the pyramid that leads to a natural cave below. Edward H. Thompson excavated this cave in the late 19th century, and because he found several skeletons and artifacts such as jade beads, he named the structure '''The High Priests' Temple.''' Archeologists today believe neither that the structure was a tomb nor that the personages buried in it were priests. The
Temple of Xtoloc is a recently restored temple outside the Osario Platform is. It overlooks the other large cenote at Chichen Itza, named after the Maya word for iguana, "Xtoloc." The temple contains a series of pilasters carved with images of people, as well as representations of plants, birds, and mythological scenes. Between the Xtoloc temple and the Osario are several aligned structures: The
Platform of Venus, which is similar in design to the structure of the same name next to Kukulkan (El Castillo), the
Platform of the Tombs, and a small, round structure that is unnamed. These three structures were constructed in a row extending from the Osario. Beyond them the Osario platform terminates in a wall, which contains an opening to a sacbe that runs several hundred feet to the Xtoloc temple. South of the Osario, at the boundary of the platform, there are two small buildings that archeologists believe were residences for important personages. These have been named as the
House of the Metates and the
House of the Mestizas.
Casa Colorada Group South of the Osario Group is another small platform that has several structures that are among the oldest in the Chichen Itza archeological zone. The
Casa Colorada (Spanish for "Red House") is one of the best preserved buildings at Chichen Itza. Significant red paint was still present in the days of the 19th century explorers. Its Maya name is
Chichanchob, which according to INAH may mean "small holes". In one chamber there are extensive carved hieroglyphs that mention rulers of Chichen Itza and possibly of the nearby city of Ek Balam, and contain a Maya date inscribed which correlates to 869 AD, when ceremonies using fire were performed by lords and overseen by the king While the Casa Colorada is in a good state of preservation, other buildings in the group, with one exception, are decrepit mounds. One building is half standing, named
La Casa del Venado (House of the Deer). This building's name has been long used by the local Maya, and some authors mention that it was named after a deer painting over stucco that doesn't exist anymore.
Central Group Las Monjas is one of the more notable structures at Chichen Itza. It is a complex of Terminal Classic buildings constructed in the Puuc architectural style. The Spanish named this complex
Las Monjas ("The Nuns" or "The Nunnery"), but it was a governmental palace. Just to the east is a small temple (known as the
La Iglesia, "The Church") decorated with elaborate masks. The Las Monjas group is distinguished by its concentration of hieroglyphic texts dating to the Late to Terminal Classic. These texts frequently mention a ruler by the name of
Kʼakʼupakal.
El Caracol ("The Snail") is located to the north of
Las Monjas. It is a round building on a large square platform. It gets its name from the stone spiral staircase inside. The structure, with its unusual placement on the platform and its round shape (the others are rectangular, in keeping with Maya practice), is theorized to have been a proto-observatory with doors and windows aligned to astronomical events, specifically around the path of Venus as it traverses the heavens.
Akab Dzib is located to the east of the Caracol. The name means, in Yucatec Mayan, "Dark Writing"; "dark" in the sense of "mysterious". An earlier name of the building, according to a translation of glyphs in the Casa Colorada, is
Wa(k)wak Puh Ak Na, "the flat house with the excessive number of chambers", and it was the home of the administrator of Chichen Itza, kokom Yahawal Choʼ Kʼakʼ. INAH completed a restoration of the building in 2007. It is relatively short, only high, and is in length and wide. The long, western-facing façade has seven doorways. The eastern façade has only four doorways, broken by a large staircase that leads to the roof. This apparently was the front of the structure, and looks out over what is today a steep, dry, cenote. The southern end of the building has one entrance. The door opens into a small chamber and on the opposite wall is another doorway, above which on the lintel are intricately carved glyphs—the "mysterious" or "obscure" writing that gives the building its name today. Under the lintel in the doorjamb is another carved panel of a seated figure surrounded by more glyphs. Inside one of the chambers, near the ceiling, is a painted hand print.
Old Chichén Old Chichén (or
Chichén Viejo in Spanish) is the name given to a group of structures to the south of the central site, where most of the Puuc-style architecture of the city is concentrated.
Other structures Chichen Itza also has a variety of other structures densely packed in the ceremonial center of about and several outlying subsidiary sites.
Caves of Balankanche image of Chichen Itza's Cave of Balankanche, showing how the shape of its great limestone column is strongly evocative of the
World Tree in Maya mythological belief systems, data from a
National Science Foundation/
CyArk research partnership Approximately south east of the Chichen Itza archeological zone are a network of sacred caves known as
Balankanche (),
Balamkaʼancheʼ in Yucatec Maya). In the caves, a large selection of ancient pottery and idols may be seen still in the positions where they were left in pre-Columbian times. The location of the cave has been well known in modern times. Edward Thompson and
Alfred Tozzer visited it in 1905. A.S. Pearse and a team of biologists explored the cave in 1932 and 1936. E. Wyllys Andrews IV also explored the cave in the 1930s.
Edwin Shook and R.E. Smith explored the cave on behalf of the
Carnegie Institution in 1954, and dug several trenches to recover potsherds and other artifacts. Shook determined that the cave had been inhabited over a long period, at least from the Preclassic to the post-conquest era. On 15 September 1959, José Humberto Gómez, a local guide, discovered a false wall in the cave. Behind it he found an extended network of caves with significant quantities of undisturbed archeological remains, including pottery and stone-carved
censers, stone implements and jewelry. INAH converted the cave into an underground museum, and the objects after being catalogued were returned to their original place so visitors can see them
in situ.
Architectural Materials and Preservation Recent gamma-ray spectrometry analyses of the building stone material of the North Temple of the Great Ball Court in 2025 revealed important aspects about what materials were used during its construction, and how the deterioration process of progressing. Measurements during this study show that the limestone blocks used to build the structure are exhibiting more weathering and degradation compared to geological outcrops nearby. In this same study, analyses showed higher levels of natural radiation in local outcrops compared to the stones used in the North Temple, showing how geochemical methodologies can be used to determine how the architecture of constructed monuments can be preserved, and to predict how they will deteriorate over time. == Great Museum of Chichen Itza ==
