In Milpa Alta, people still speak the Aztec language

Milpa Alta (‘high cornfield’ in Spanish) couldn’t be more different from the smog-laden city to which it formally belongs and that it overlooks from its mountainside location. What used to be known as distant farmland and Nahua villages has slowly been ceded into the city. Although literally part of Mexico City, it's rarely visited by other Mexico City residents. Foreign tourists are even more unusual. And although it’s officially within the city limits, the people of Milpa Alta in many ways live as they have done for hundreds of years.
