Mexico City - Distrito Federal

Mexico City is considered the world's second largest and most populated city, built on the dry bed of lake Texcoco, surrounded on three sides by tall mountains and volcanoes such as the Ajusco, the Popocatepetl and the Ixtlacihuatl. It's a massive urban sprawl, stretching from Mexico State in the north, through the Federal District. Estimates place the population of the full metropolitan area at 20 million people. It is the most important economic, industrial and cultural center in the country.
