About the area:
An expansive city of 20 million and over a mile high is built on the ruins of Tenochtitlan, the ancient Aztec capital. Reminders of past civilization pervade the city, particularly at the Templo Mayor excavation and Anthropological Museum at Chapultepec Park. Fine shops can be found in profusion in the Zona Rosa.
Mexico City, called D. F. (for Distrito Federal; Federal District) or simply Mexico, is the capital, seat of government and the center of commerce, finance and the arts; in addition to being the largest city in the world.
