Its foundation goes back to the year 500 A.C. “Cholula has been translated from the Nahuatl language like “Water that falls in the place of fled” This has relation with the arrival of the Toltecas to the valley after their expulsion from Tula, around the year 1000. They were indeed the toltecas that formed here the greatest ceremonial center of the Anahuac, turning Cholula into the “Sacred City” . The pre-Hispanic name of Cholula is Tollan Chollolan Tlachiualtepetl that is translated like “the city of which they fled where the hill is handmade ". Cholula was one of the first places selected to locate a small village, probably towards the closing of second millennium A. C. The population increased during the following centuries giving a rise in a greater social inequality and the creation of ideologies to endorse it. The great pyramid is the physical manifestation of these concepts. Its first constructive stage is was during the second century of our era. In the antiquity it was known as tlachihualtepec, the “handmade hill”, so that according to the legend it was constructed with adobes done by giants. This initial structure rose in two episodes to get to form a platform of 120m. By side and 18m. Of height with a stair access to the west and a temple in its top. It was oriented, like all the buildings of the Sacred City, 24º to the east of the north seeing towards the Iztlaccihualtl. Between the modifications and additions done to it, the most important one was the positioning of the architectonic system slope-board also used in Teotihuacan in two of its seven bodies. With the construction of this pyramid, buildings and patios around its base were annexed creating a constructive complex mass difficult to decipher, archeologists calculate that during its last stage, it measured 400 meters by side and between 62 and 65 meters of height without counting the temple that was crowned it in its superior part, constructing the plinth of greater volume in the American continent. Where now lays the church dedicated to Nuestra Señora de los Remedios. The Toltecas built a new ceremonial center around the greater seat of Cholula and raised their temple dedicated to Quetzalcoatl, where now the Franciscan convent of San Gabriel is located. Other buildings have disappeared under the streets and constructions of the post-conquered city, as the Calmecac or school for noble and priests. The Xiuhcalli, the House of Turquoise, where the advice of six noble met, was replaced by the vestibule of the City council located to the west of the central seat, second in size in present Mexico, nowadays that same building shines with a vestibule of 46 arcs of average point that form a gallery of 170 meters, without a doubt one of the longest ones in Latin-America.
