Chichen Itza, a UNESCO World Heritage Site, is one of the main archaeological sites on the Yucatán Peninsula and one of the most popular tourist destinations in the world and the second most visited in Mexico. One of the Seven Wonders of the Modern World is the holy city that was founded by Itza, the so-called water wizard, experienced a political and cultural renaissance in the 5th century AD with people and Toltec influences that made it one of the mainstays of power in the Yucatán Peninsula. consolidated as the centre. Around the year 1250 AD the city was abandoned for completely determined reasons, but its power was so great that it was still a place of pilgrimage and worship for centuries after its fall. Two construction styles can be distinguished here that are a reflection of the two distinct periods that created it: the oldest emerged during the Terminal Classic (600–800/900) of the Puk tradition and the other the Early Postclassic (900–1200). . known as the Toltec Maya. The oldest part of the city is known as Chichén Viejo and is concentrated in the southern region, where the Xtoloc cenote used to be. Its buildings are not as grand as those later built to the north, but they stand out for their sumptuous Puk-style decoration. It was in the second period, the period of greatest grandeur, when the most majestic buildings were built, such as the Temple of the Warriors, the Complex of Thousand Pillars, the Platform of Venus or the Great Ball Court. The Pyramid or Palace of Kukulcán is the main building in the city of Chichen Izta and one of the tallest and most notable examples of Maya architecture built during the fall of Mayapan, the height of the Itza-Cocom culture. It is a four-sided pyramid with a rectangular temple at the top with a height of 24 meters. Four staircases that are distributed along each side of it add up to 365 steps for each day of the year. Clumps of stone flank each one, and at the base of the north staircase are two huge winged serpent heads, effigies of the god Kukulcan. Another outstanding construction is the effigy ball game court of the god Kukulcán Rocío Jiménez, 120 meters long and 30 meters wide, the largest and best preserved in the entire Mesoamerican region. It was more of a ceremonial ritual than a game and probably represented a symbolic recreation of the mythical battle between night and day. The ballcourt has a unique acoustic phenomenon: if one speaks at the southern end of the temple, the voice can be heard at the opposite end, as the sound resonates along the walls of the northern temple. Temple of the Warriors, El Caracol and Casa de las Monjas Rocío Jiménez For its part, the Temple of the Warriors is one of the most impressive structures at this archaeological site. It may be the only known Late Classic Maya building large enough to host large gatherings. This 12 meter high structure, 40 meters wide, has four platforms which are surrounded by 200 round and square pillars on the south and west sides. The central temple shows bas-reliefs of warriors, eagles and jaguars who devour human hearts. There are also representations of the god Tlchitontiuh and Chalk Mool in the engravings. In addition, Caracol stands out, one of the few circular structures built by the Mayans that were used for astronomical observation through an opening in the upper part of the tower and which has a total height of 23 meters, the Casa de las Monzas, of which Its façade is decorated in the Chensa style, with the Temple of Thousand Pillars and the Sacred Cenote, a naturally nearly circular open well that was the center of religious activity not only in the city of Chichen Itza but throughout. Maya area. This was a reason to worship Chak, the god of rain, which dates from the Late Classical period in the year 650 AD and continued until the end of the Postclassic in 1350 AD, with its muddy bottom, gold, jade, copper, cloth and baskets. Goods have been removed, which were apparently thrown as ceremonial offerings. Equinox Show Only twice a year this archaeological site hosts one of the most magical light shows in the world. During the spring and autumn equinoxes, it is said that the god Kukulcan descends to earth to bless the crops. At about three o’clock in the afternoon the sun shines a seven triangle light on the balustrade on the north side of the Pyramid of Kukulcan. These begin to move along the balustrade to form the silhouette of the snake. As the hours go by, it seems to make its way down and ends in the stone head at the bottom of the stairs.
