Mexico - Ciudád de México

Mexico City officially known as México, D. F., or simply D. F.) is the federal district (distrito federal), capital of Mexico and seat of the federal powers of the union. Mexico City is located in the Valley of Mexico, sometimes called the Basin of Mexico. This valley is located in the Trans-Mexican Volcanic Belt in the high plateaus of south-central Mexico. It has a minimum altitude of 2,200 meters (7,200 feet) above sea level and is surrounded by mountains and volcanoes that reach elevations of over 5,000 meters.
Teotihuacan was a pre-Columbian Mesoamerican city located in the Valley 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. Apart from the pyramids, Teotihuacan is also anthropologically significant for its complex, multi-family residential compounds, theAvenue of the Dead, and the small portion of its vibrant murals that have been exceptionally well-preserved. The city is thought to have been established around 100 BC, with major monuments continuously under construction until about AD 250.
