Cholula (Mesoamerican site)
Cholula (Spanish ), was an important city of pre-Columbian Mesoamerica, dating back to at least the 2nd century BC, with settlement as a village going back at least some thousand years earlier. The great site of Cholula stands just west of the modern city of Puebla and served as a trading outpost. Its immense pyramid is the largest such structure in the Americas, and the largest pyramid structure by volume in the world.
