This room is located in a cavity beneath the side of the Periférico and has preserved one of the few vestiges of Mexica architecture made of adobe. Among its exhibits, visitors can see graphics and infographics, learn about the remains of pre-Hispanic buildings, and see evidence of Teotihuacan and Mexica occupations in the area. The purpose of the room is to teach visitors about the history and archaeology of this place. The National Coordination of Museums and Exhibitions was responsible for the adaptation of the Introductory Room. Did you know? This important pre-Hispanic site has been researched for over a century. The first description of the remains was made in 1916 by historian Francisco Fernández del Castillo, who named the site Mixcoac after identifying the place name “La serpiente de nubes” (The Cloud Serpent) on the Uppsalao de Santa Cruz Map, drawn up in 1550.

In 1920, archaeologist Eduardo Noguera, appointed by Manuel Gamio, then director of Pre-Hispanic Monuments, led the first archaeological excavation to study the large mound that was visible in the area south of Tacubaya, which was known as “el teocallide San Pedro de los Pinos.”
