Etapa 1 del Templo Mayor de Mexico Tlatelolco

En 1998 Eduardo Matos excavó con Francisco Hinojosa la mitad sur de la Etapa II del Templo Mayor descubriendo las estructuras que Antonieta Espejo llamó Tlatelolco I en 1944. Para 1992, Salvador Guilliem propuso explorar el inmueble mediante 2 túneles que ingresaran desde el desplante de inmueble cortando hasta el centro del inmueble para registrar todas las estructuras presentes y recolectando todos los artefactos que permitieran verificar la fundación de Mexico Tlatelolco. Así desde esa fecha y hasta 2011 se excavó, primero localizando escalinatas inmediatas a la Etapa II, y que se le llamó Etapa Ia. Se localizaron restos de otra escalinata más que se llamó Etapa IB y finalmente a 8 metros de profundidad y justo al centro se descubrió una pilastra que desplanta de un piso estucado y que acorde a los materiales y forma de construcción podemos considerar que corresponde a un edificio construido en la época de los toltecas, tal como lo afirma la Historia Tolteca Chichimeca.

They discovered structures that Antonieta Espejo named Tlatelolco 1 in 1944. By 1992 archaeologists suggested exploring the building by using two tunnels that went in through the entrance of the building all the way up to the center, this way they could register all the structures that were there and the artifacts that could help make out the foundation of Mexico Tlatelolco. So, the site was explored from that year until 2011. First a stairway to stage 2 was located and it was named "Etapa 1a" (Stage 1A). Remains of another stairway was located and it was named Stage 1B and finally at about 26 ft of depth and right in center of a pilaster that stuck out from the floor was found. According to its shape and the materials that were used in its construction it can be considered to belong to a building built in the period of the Toltecas, as confirmed by the Tolteca Chichimeca history.
