Mexico City (Spanish: México, Ciudad de México, or D.F. (pronounced deh eh-feh)) is Mexico's capital.
The city is built on the ruins of the Aztec capital Tenochtitlan, and later came to be the capital of New Spain, which included much of North America. The city has grown fast in the 20th century, and is today North America's largest city (and the world's largest Spanish-speaking city) with 8.9 million inhabitants in the city proper, and more than 20 million in the urban area.
The city is officially divided into 16 delegaciones (boroughs) which are in turn subdivided into colonias (neighborhoods), of which there are around 2150; however, it is better to think of the city in terms of districts to facilitate the visitor getting around. Many older towns like Coyoacán, San Angel and Tlalpan got merged into the urban sprawl, and each of these still manages to preserve some of their original and unique characteristics. Read more
