Zócalo · Centro Histórico
The largest plaza in Latin America was built on top of a destroyed civilization
The Zócalo — officially Plaza de la Constitución — sits directly on the ruins of Tenochtitlán, the Aztec capital that the Spanish conquistadors demolished stone by stone in 1521. The Metropolitan Cathedral was built using rubble from Aztec temples. Beneath the square, archaeologists have found layers of the original city that once held up to 200,000 inhabitants, making it one of the largest cities in the world at the time.
