The Great Pyramid of Cholula, also known as Tlachihualtepetl (Nahuatl for "made-by-hand mountain"), is a huge complex located in Cholula, Puebla, Mexico. It is the largest archaeological site of a pyramid (temple) in the New World, as well as the largest pyramid known to exist in the world today.
The pyramid stands 55 metres (180 ft) above the surrounding plain, and in its final form it measured 450 by 450 metres (1,480 by 1,480 ft). The pyramid is a temple that traditionally has been viewed as having been dedicated to the god Quetzalcoatl.
The architectural style of the building was linked closely to that of Teotihuacan in the Valley of Mexico, although influence from the Gulf Coast also is evident, especially from El Tajín.
The Great Pyramid was an important religious and mythical centre in prehispanic times. Over a period of a thousand years prior to the Spanish Conquest, consecutive construction phases gradually built up the bulk of the pyramid until it became the largest in Mexico by volume. It was built during the period from Classic to Postclassic.
