Mexical City - April 2015

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 of the Spanish conquistadors and the Palacio Nacional, which houses historic murals by Diego Rivera. All of this resides in and around the Plaza de la Constitución, the massive main square also known as the Zócalo.

Teotihuacan /teɪˌoʊtiːwəˈkɑːn/, also written Teotihuacán (Spanish), was an ancient Mesoamerican city located in a sub valley of the Valley of Mexico, located in the State of Mexico 30 miles (48 km) northeast of modern-day Mexico City, known today as the site of many of the most architecturally significant Mesoamerican pyramids built in the pre-Columbian Americas.
