The Pueblos Originarios of La GAM (Gustavo A. Madero) in the very north of Mexico City, are among the oldest, and some of those most in danger. Nearly entirely lost in the urban fabric of Mexico City, most of them are little more than ghosts.
The names are carried on in a public market, and here and there in the name of neighborhood. But by and large the imprint of history is as lost as the old salt flats at the edge of the northern lake.
Nevertheless, the layers of urban life continue to be laid down. Here and there we can catch glimpses of the past. The Villa de Guadalupe, a colonial era city, entirely dominated it's predecessor. Tepeyac makes up three of the original villages, but was a city unto itelf. Here's a quick guide to the GAM pueblos originarios and how to find them.
