The Hidden Giant: The Great Pyramid of Cholula

Imagine walking up a grassy, green hill in the city of Cholula, Mexico. At the very top sits a beautiful Spanish church with bright domes reaching toward the sky. It looks like a peaceful, natural park. But beneath the grass, trees, and soil lies a massive ancient secret. You are not standing on a hill at all. You are walking on top of the Great Pyramid of Cholula, the largest monument ever built by humans anywhere in the world.

When people think of giant pyramids, they usually picture the pointed stone structures in Egypt. However, the Great Pyramid of Cholula is much larger in terms of volume, which is the amount of physical space an object takes up. Its base is so huge that it covers nearly forty-five acres. That is big enough to fit nine football fields! While it is not as tall as the famous pyramids in Egypt, its massive base makes it the largest pyramid on Earth by far.

This giant structure was not built all at once. Instead, it was created over a period of nearly a thousand years, starting around 300 BCE. Different ancient civilizations lived in this region over the centuries. Every time a new group of people took control of the city, they did not tear down the old temple. Instead, they built a brand-new, larger pyramid directly over the old one. Over time, the pyramid grew outward and upward, layer by layer, like a giant set of nesting dolls.

By the time Spanish explorers arrived in Cholula in the early 1500s, the pyramid had been abandoned for many years. Because it was made of mud bricks and plaster, nature had slowly reclaimed it. Grass, bushes, and trees grew over the flat terraces, completely hiding the ancient temple. The Spanish thought the structure was just a natural hill. In 1594, they built a church called the Iglesia de Nuestra Señora de los Remedios right on the summit, or the very peak, of the hill.

Today, the Great Pyramid of Cholula remains mostly hidden, looking like a natural mountain topped by a church. However, scientists called archaeologists have spent decades studying it. Because they cannot dig up the historic church on top, they have dug over five miles of tunnels inside the hill instead. Visitors today can walk through these narrow, stone tunnels to see the hidden staircases, ancient walls, and colorful paintings created by artists thousands of years ago. It stands as a wonderful reminder of the incredible history buried just beneath our feet.
