The El Conde archeological site in the district and municipality of Naucalpan de Juárez presents a large square platform. The history of the settlement goes back to the final stage of Teotihuacan (600-800), since fragments of ceramic material have been found from this period. Remains from the Toltec period (800-1100) and Early Postclassic (1200-1430) have also been found.

This great platform might also have been the site of a palace or tecpan because there is an east-west oriented access stairway, on both sides of which rooms were appended, a very common feature for this type of construction. The architectural shape of the platform is typical of the palaces found in the Valley of Mexico in the Late Postclassic, as can also be seen in several pre-Hispanic and colonial codices, including the Quinantzin Codex.
