Among the archaeological finds are the skeletal remains of Spanish men, women, and children, both Black and mixed-race, who were part of the caravan to capture Hernán Cortés.

The settlement dates back to the Classic Period, related to the early ceramic phase of Xalalpan, approximately 450 AD. It is located on a hill in the Sierra Nevada of Mal País and covers an area of approximately 80 hectares. Its geographic position on the eastern side of the Valley of Mexico basin and its control over the Apam plains played a very important role in its development, allowing for the control and flow of diverse goods, from agricultural products to luxury goods, to Teotihuacan, Texcoco, and Tenochtitlan during their respective periods of prosperity. The architectural characteristics that define the oldest occupational level in this area are clearly influenced by the Teotihuacan culture, as its ancient inhabitants settled there during the period of greatest development of the great city and abandoned it at the time of its fall. Thanks to recent excavations, archaeological discoveries, and the interpretation of 16th-century colonial sources, it has been possible to accurately identify the true name of the site: Sultepec, not Tecoaque, as it was known in colonial times. Experts believe that the Spaniards, mestizos, Sambos, mulattoes, macehuales, Blacks, and Creoles who were part of the caravan captured by the Acolhua in 1520 were sacrificed in these temples. Some of them were eaten by the local residents in search of the transmutation of their energy, according to chroniclers Bernal Díaz del Castillo and Francisco López de Gómara in their books True History of the Conquest of New Spain and General History of the Indies, respectively, as well as the Letters of Relation that Hernán Cortés sent to King Charles I of Spain, and the Codex Xolotl.
