The Great Pyramid of Cholula is not only the biggest in Mexico, but it’s also in the Guinness Book of Records as the largest emblematic monument ever built in the world. This temple-pyramid has a base of 450 meters by 450 meters, a height of 66 meters, and an estimated volume of over 4.45 million cubic meters. Despite being almost twice the size of Egypt’s Great Pyramid of Giza, the Pyramid of Cholula actually remains hidden under a mountain.
