Founded by the Aztecs in the 14th century, Mexico City is a melting pot of history and culture, where its ancient past and fashionable present blend to create a unique synergy with a foot in both worlds. The 20 million plus people that live in the Valley of Anahuac – once an enormous lake – are blessed with constant views of the snow-capped volcanoes of Popocatépetl and Iztaccíhuatl.
