The Great Pyramid of Cholula, the world's largest monument and largest Pre-Columbian pyramid by volume, is a huge complex located in Cholula, Puebla, Mexico. Only a fraction of a staircase on one side of the Great Pyramid of Cholula has been restored.

The temple-pyramid complex was built over many dozens of generations, from the 2nd century BC to the early 16th century, and was dedicated to the deity Quetzalcoatl. It has a base of 450 by 450 m (1476x1476 ft) and a height of 66 m (217 ft). According to the Guinness Book of Records, it is in fact the largest pyramid as well as the largest monument ever constructed anywhere in the world, with a total volume estimated at 4.45 million m³, almost one third larger than that of the Great Pyramid of Giza in Egypt. (The Giza pyramid is taller, however.) The Aztecs believed that Xelhua built the Great Pyramid of Cholula.
