"Auh niman iconmiquanique in Tlemaco in mexica. Inipan acatli ipan macuilxiuhtique in Tlemaco in mexica." "And the Mexicans went to Tlemaco. The Mexicans remained in Tlemaco for five years." In contrast to what is reported in the Boturini Codex, the Aubin Codex records the founding of Tlamaco in the year 8-Caña (1174), however both sources coincide in the time of permanence of the Mexicans. Aztecs in Tlamaco, their origin from Atitalaquia and their subsequent departure to Atotonilco.

During the territorial expansion of the Triple Alliance, Moctezuma Ilhuicamina conquered the region of Teotlalpan, north of the Mexica Empire. With this, Tlamaco became a tributary of Tenochtitlan until the arrival of the Spanish.

After the conquest of Mexico, Tlamaco became a Spanish encomienda, as recorded in the Painting of the governor, mayors and aldermen of Mexico of 1556; However, the assignment of the encomienda by Hernán Cortés dates back to 1530 with the early conquest of the territories of Atitalaquia. Years later, the viceroy Martín Enríquez de Almansa ordered that the indigenous people join their houses to form towns.

The Franciscan order was in charge of carrying out the work of evangelization in Tlamaco, consisting of teaching the indigenous people the Spanish language, Catholic doctrine and new forms of cultivation. In the 1570s, the friars were in charge of leading the inhabitants of Tlamaco in the construction of a chapel in honor of San Jerónimo using the area's pink quarry as raw material. The chapel is barrel-vaulted and originally had a cypress on the altar. The façade contains elements of the Plateresque style and its engravings are an example of tequitqui. Additionally, it has an open chapel in the shape of arcades.
