Name and orthography

The Maya name "Chich'en Itza" means "At the mouth of the well of the Itza." This derives from chi, meaning "mouth" or "edge", and ch'en or ch'e'en, meaning "well." Itzá is the name of an ethnic-lineage group that gained political and economic dominance of the northern peninsula. One possible translation for Itza is "wizard (or enchantment) of the water."

The name is often represented as Chichén Itzá in Spanish and when translated into other languages from Spanish to show that both parts of the name are stressed on their final syllables. Other references prefer to employ a more rigorous orthography

This name is difficult to define because of the absence of a single standard of orthography, but it is represented variously as Uuc Yabnal, Uuc Hab Nal, or Uc Abnal. While most sources agree the first word means seven, there is considerable debate as to the correct translation of the rest. Among the translations suggested are “Seven Bushes,” “Seven Great Houses,” or “Seven Lines of Abnal.”

History

Northern Yucatán is arid, and the rivers in the interior all run underground. There are two large, natural sink holes, called cenote

. The art and architecture from this period shows an interesting mix of Maya and Toltec styles. However, the recent re-dating of Chichen Itza's decline (see below) indicates that Chichen Itza is largely a Late/Terminal Classic site, while Tula remains an Early Postclassic site (thus reversing the direction of possible influence).

Political organization

Several archaeologists in late 1980s suggested that unlike previous Maya polities of the Early Classic, Chichen Itza may not have been governed by an individual ruler or a single dynastic lineage. Instead, the city’s political organization could have been structured by a "multepal" system, which is characterized as rulership through council composed of members of elite

 ruling lineages. This theory was popular in the 1990s, but in recent years, the research that supported the concept of the "multepal" system has been called into question, if not discredited. The current belief trend in Maya scholarship is toward the more traditional model of the Maya kingdoms of the Classic southern lowlands.

Economy

Chichen Itza was a major economic power in the northern Maya lowlands during its apogee. Participating in the water-borne circum-peninsular trade route through its port site of Isla Cerritos, Chichen Itza was able to obtain locally unavailable resources from distant areas such as central Mexico (obsidian

) and southern Central America (gold).

, conquered Chichen Itza in the 13th century. Hunac Ceel supposedly prophesied his own rise to power. According to custom at the time, individuals thrown into the Cenote Sagrado were believed to have the power of prophecy if they survived. During one such ceremony, the chronicles state, there were no survivors, so Hunac Ceel leaped into the Cenote Sagrado, and when removed, prophesied his own ascension.

While there is some archaeological evidence that indicates Chichén Itzá was at one time looted and sacked, there appears to be greater evidence that it could not have been by Mayapan, at least not when Chichén Itzá was an active urban center. Archaeological data now indicates that Chichen Itza fell by around AD 1000, some two centuries before the rise of Mayapan. Ongoing research at the site of Mayapan may help resolve this chronological conundrum.

While Chichén Itzá “collapsed” (meaning elite activities ceased) it may not have been abandoned. When the Spanish arrived, they found a thriving local population, although it is not clear from Spanish sources if Maya were living in Chichen Itza or nearby. The relatively high density of population in the region was one of the factors behind the conquistadors' decision to locate a capital there (See "Spanish Arrival" below). According to post-Conquest sources, both Spanish and Maya, the Cenote Sagrado remained a place of pilgrimage.

 on the west coast. He sent his son, Francisco Montejo The Younger, in late 1532 to conquer the interior of the Yucatán Peninsula from the north. The objective from the beginning was to go to Chichén Itzá and establish a capital.

Montejo the Younger eventually arrived at Chichen Itza, which he renamed Ciudad Real. At first he encountered no resistance, and set about dividing the lands around the city and awarding them to his soldiers. The Maya became more hostile over time, and eventually they laid siege to the Spanish, cutting off their supply line to the coast, and forcing them to barricade themselves among the ruins of ancient city. Months passed, but no reinforcements arrived. Montejo the Younger attempted an all out assault against the Maya and lost 150 of his remaining forces. He was forced to abandon Chichén Itzá in 1534 under cover of darkness. By 1535, all Spanish had been driven from the Yucatán Peninsula.

Montejo eventually returned to Yucatán and, by recruiting Maya from Campeche and Champoton, built a large Indio-Spanish

 army and conquered the peninsula. The Spanish crown later issued a land grant that included Chichen Itza and by 1588 it was a working cattle ranch.

Site description

The site contains many fine stone buildings in various states of preservation, and many have been restored. The buildings are connected by a dense network of formerly paved roads, called sacbe
Sacbe
right|thumb|Sacbe at Dzibilchaltun in the Yucatánthumb|right|Arch at the end of the sacbé, Kabah, YucatánSacbe, plural Sacbeob, or "white ways" are raised paved roads built by the Maya civilization of pre-Columbian Mesoamerica...

ob. Archaeologists have found almost 100 sacbeob criss-crossing the site, and extending in all directions from the city.

The buildings of Chichén Itza are grouped in a series of architectonic sets, and each set was at one time separated from the other by a series of low walls. The three best known of these complexes are the Great North Platform, which includes the monuments of El Castillo, Temple of Warriors and the Great Ball Court; The Ossario Group, which includes the pyramid of the same name as well as the Temple of Xtoloc; and the Central Group, which includes the Caracol, Las Monjas, and Akab Dzib.

South of Las Monjas, in an area known as Chichén Viejo (Old Chichén) and only open to archaeologists, are several other complexes, such as the Group of the Initial Series, Group of the Lintels, and Group of the Old Castle.

El Castillo

Dominating the main platform of Chichén is the Temple of Kukulkan
Kukulkan
Kukulkan is the name of a Maya snake deity that also serves to designate historical persons. The depiction of the feathered serpent deity is present in other cultures of Mesoamerica. Kukulkan is closely related to the god Q'uq'umatz of the K'iche' Maya and to Quetzalcoatl of the Aztecs...

, slightly more than 29 meters high, consists of a series of square terraces, each slightly more than 2.5 meters high, with a 6-meter-high temple at the top. The sides of the pyramid are approximately 55.3 meters at the base and rise at an angle of 53 degrees, although that varies slightly for each side. The four faces of the pyramid have protruding stairways that rise at a 45-degree angle. At the base of the balustrades of the northern staircase are carved heads of a serpent.

Mesoamerican cultures periodically built larger structures atop older ones, and this is one such example. In the mid 1930s, the Mexican government sponsored an excavation of 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 and 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.

On the Spring and Autumn equinox, 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. Some have suggested the effect was an intentional design by the Maya builders to represent the feathered-serpent god Kukulcan. Archaeologists have found no evidence to support such an assertion.

Great Ball Court

Archaeologists have identified several courts for playing the Mesoamerican ballgame

 in Chichén, but the Great Ball Court about 150 metres (492.1 ft) 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 m (544.6 by 223.1 ft). The imposing walls are 12 metres (39.4 ft) 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 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.

. In its interior archaeologists discovered a collection of large cones carved out of stone, the purpose of which is unknown. This platform is placed between El Castillo and the Cenote Sagrado.

Sacbe Number One

This sacbe, which leads to the Cenote Sagrado, is the largest and most elaborate at Chichen Itza. This “white road” is 270 metres (885.8 ft) long with an average width of 9 metres (29.5 ft). It begins at a low wall a few metres from the Platform of Venus. According to archaeologists there once was an extensive building with columns at the beginning of the road.

Temple of the Tables

To the east of El Castillo is a series of buildings, the northernmost is the Temple of the Tables. 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.”

. 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 Institute of Washington from 1925–1928. 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.

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: an east group, that extends the lines of the front of the Temple of Warriors; a north group, which runs along the south wall of the Temple of Warriors and contains pillars with carvings of soldiers in bas-relief; and a northeast group, which apparently formed a small temple at the southeast corner of the Temple of Warriors, which 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 40 metres (131.2 ft) 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. The Temple of the Small Tables which has an exterior motif of x’s and o’s. And the Palace of Ahau Balam Kauil (also known as Thompson’s Temple), a small building with two levels that has friezes depicting Jaguars (balam in Maya) as well as glyphs of the Maya god Kahuil.

Steam Bath

This unique building has three parts: a waiting gallery, a water bath, and a steam chamber that operated by means of heated stones.

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, archaeologists believe that its purpose was more ceremonial than commerce.

Ossario 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.

Ossario

Like El Castillo, this step-pyramid temple dominates the 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 El Castillo, at the center is an opening into the pyramid which leads to a natural cave 12 metres (39.4 ft) 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. Archaeologists today believe neither that the structure was a tomb nor that the personages buried in it were priests.

Temple of Xtoloc

Outside the Ossario Platform is this recently restored temple which 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 Ossario are several aligned structures: Platform of Venus (which is similar in design to the structure of the same name next to El Castillo), Platform of the Tombs, and a small, round structure that is unnamed. These three structures were constructed in a row extending from the Ossario. Beyond them the Ossario platform terminates in a wall, which contains an opening to a sacbe that runs several hundred feet to the Xtoloc temple.

House of the Metates and House of the Mestizas

South of the Ossario, at the boundary of the platform, there are two small buildings that archaeologists believe were residences for important personages.

The Casa Colorada Group

South of the Ossario Group is another small platform that has several structures that are among the oldest in the Chichen Itza archaeological zone.

Casa Colorada

The Casa Colorada, which is Spanish for Red House, is one of the best preserved buildings at Chichen Itza. It also has a Maya name, 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 a.d.e., one of the oldest such dates found in all of Chichen Itza.

In 2009, INAH restored a small ball court that adjoined the back wall of the Casa Colorada.

The House of the Deer

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 Casa del Venado (House of the Deer). The origin of the name is unknown, as there are no representations of deer or other animals on the building.

Las Monjas

One of the more notable structures at Chichen Itza is a complex of Terminal Classic buildings constructed in the Puuc

.

El Caracol

To the north of Las Monjas is a cockeyed, round building on a large square platform. It's nicknamed El Caracol ("the snail") because of 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

Located to the east of the Caracol, Akab Dzib means, in Maya, "Dark (in the "Mysterious" sense) Writing." 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 Chichén Itzá, kokom Yahawal Cho' K’ak’. INAH completed a restoration of the building in 2007. It is relatively short, only 6 metres (19.7 ft) high, and is 50 metres (164 ft) in length and 15 metres (49.2 ft) wide. The long, western-facing facade has seven doorways. The eastern facade 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, but 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 door jamb 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 Chichen

"Old Chichen" is the nickname for a group of structures to the south of the central site. It includes the Initial Series Group, the Phallic Temple, the Platform of the Great Turtle, the Temple of the Owls, and the Temple of the Monkeys.

Other structures

Chichen Itza also has a variety of other structures densely packed in the ceremonial center of about 5 square kilometre and several outlying subsidiary sites.

Caves of Balankanche

Approximately 4 km (2.5 mi) west of the Chichen Itza archaeological zone are a network of sacred caves known as Balankanche , Balamka'anche' in Modern 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

 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 archaeological remains, including pottery and stone-carved censer

s, 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.

 and committed to conduct long-term archaeological research at Chichen Itza. The Mexican Revolution and the following government instability, as well as World War I, delayed the project by a decade.

In 1923, the Mexican government awarded the Carnegie Institution a 10-year permit (later extended another 10 years) to allow U.S. archaeologists to conduct extensive excavation and restoration of Chichen Itza. Carnegie researchers excavated and restored the Temple of Warriors and the Caracol, among other major buildings. At the same time, the Mexican government excavated and restored El Castillo and the Great Ball Court.
In 1926, the Mexican government charged Edward Thompson with theft, claiming he stole the artifacts from the Cenote Sagrado and smuggled them out of the country. The government seized the Hacienda Chichén. Thompson, who was in the United States at the time, never returned to Yucatán. He wrote about his research and investigations of the Maya culture in a book People of the Serpent published in 1932. He died in New Jersey in 1935. In 1944 the Mexican Supreme Court ruled that Thompson had broken no laws and returned Chichen Itza to his heirs. The Thompsons sold the hacienda to tourism pioneer Fernando Barbachano Peon.

There have been two later expeditions to recover artifacts from the Cenote Sagrado, in 1961 and 1967. The first was sponsored by the National Geographic, and the second by private interests. Both projects were supervised by Mexico's National Institute of Anthropology and History

After Edward Thompson in 1894 purchased the Hacienda Chichén, which included Chichen Itza, he received a constant stream of visitors. In 1910 he announced his intention to construct a hotel on his property, but abandoned those plans, probably because of the Mexican Revolution.

In the early 1920s, a group of Yucatecans, led by writer/photographer Francisco Gomez Rul, began working toward expanding tourism to Yucatán. They urged Governor Felipe Carrillo Puerto to build roads to the more famous monuments, including Chichen Itza. In 1923, Governor Carrillo Puerto officially opened the highway to Chichen Itza. Gomez Rul published one of the first guidebooks to Yucatán and the ruins.

Gomez Rul's son-in-law, Fernando Barbachano Peon (a grandnephew of former Yucatán Governor Miguel Barbachano
Miguel Barbachano
Miguel Barbachano y Tarrazo was a liberal Yucatecan politician, who was 5 times governor of Yucatán between 1841 and 1853....

), started Yucatán’s first official tourism business in the early 1920s. He began by meeting passengers that arrived by steamship to Progreso, the port north of Mérida, and persuading them to spend a week in Yucatán, after which they would catch the next steamship to their next destination. In his first year Barbachano Peon reportedly was only able to convince seven passengers to leave the ship and join him on a tour. In the mid-1920s Barbachano Peon persuaded Edward Thompson to sell 5 acres (20,234.3 m²) next to Chichen for a hotel. In 1930, the Mayaland Hotel opened, just north of the Hacienda Chichén, which had been taken over by the Carnegie Institution.

In 1944, Barbachano Peon purchased all of the Hacienda Chichén, including Chichen Itza, from the heirs of Edward Thompson. Around that same time the Carnegie Institution completed its work at Chichen Itza and abandoned the Hacienda Chichén, which Barbachano turned into another seasonal hotel.

In 1972, Mexico enacted the Ley Federal Sobre Monumentos y Zonas Arqueológicas, Artísticas e Históricas (Federal Law over Monuments and Archeological, Artistic and Historic Sites) that put all the nation's pre-Columbian monuments, including those at Chichen Itza, under federal ownership. There were now hundreds, if not thousands, of visitors every year to Chichen Itza, and more were expected with the development of the Cancún

In the 1980s, Chichen Itza began to receive an influx of visitors on the day of the spring equinox. Today several thousand show up to see the light-and-shadow effect on the Temple of Kukulcan in which the feathered serpent god supposedly can be seen to crawl down the side of the pyramid. Tourists are also wondered by the acoustics at Chicen Itza. For instance a handclap in front of the staircase of the El Castillo pyramid is followed by an echo that resembles the chirp of a quetzalcoatl

 after a worldwide vote. Despite the fact that the vote was sponsored by a commercial enterprise, and that its methodology was criticized, the vote was embraced by government and tourism officials in Mexico who project that as a result of the publicity the number of tourists expected to visit Chichen will double by 2012.

The ensuing publicity re-ignited debate in Mexico over the ownership of the site, which culminated on 29 March 2010 when the state of Yucatán purchased the land upon which the most recognized monuments rest from owner Hans Juergen Thies Barbachano.

Over the past several years, INAH, which manages the site, has been closing monuments to public access. While visitors can walk around them, they can no longer climb them or go inside their chambers. The most recent was El Castillo, which was closed after a San Diego, California, woman fell to her death in 2006.
