Explanation:

Mexico City is the densely populated, high-altitude capital of Mexico. It's known for its Templo Mayor (a 13th-century Aztec temple), the baroque Catedral Metropolitana de México of the Spanish conquistadors and the Palacio Nacional, which houses historic murals by Diego Rivera. All of these are situated in and around the Plaza de la Constitución, the massive main square also known as the Zócalo.
