We visited Cholula where a significant city once stood including a great pyramid- larger than the pyramid's of Egypt. Unfortunately the people were allies of the Aztecs and tried to ambush Cortes. In true conquistador style, he wipe them out and leveled everything he could find, then they built churches on top of it all.
