Montecillo... Has what you like about a group of Otomi Indians around 1600 and a Tarascan avecindaron part of the ejidos in the east of the city of San Luis Potosí. The new settlement was small in size: it consisted of only two leagues, measured in city terms towards the Cerro de San Pedro, and less than a quarter of a league wide. The name of Montecillo, adopted from the beginning by its inhabitants according to the titles of construction of the village, derived from the fact that the lands in which they originally settled were harsh, hilly and sterile. In this phase of its history, since it could not be a formal settlement, it lacked autonomy and, on an ecclesiastical level, was subject to the parish of the city of San Luis Potosí. As in the rest of the Indian peoples, several families of coyotes, mestizos and mulattoes settled here too, who united and coexisted peacefully with the Indians. The dedication and work of its inhabitants soon bore fruit; in the early years they broke up the land, opened streets and roads, built jacales, formed gangs, dug wells to draw water for human consumption, and grew corn, which they harvested with the rains. From the early years the new settlement was considered an important supplier of manpower for the benefit of the metallurgical companies located in the direction of La Laguna. The impetus initially shown by its inhabitants waned over time, and only occurred between the end of the 17th century and the beginning of the 18th CENTURY when a phase of sustained growth began, which in some way resulted from the establishment of a "room" used a cappella.

In 1753 the chapel was 26 meters long and 8 meters wide. It had all the ornaments and tools necessary to celebrate mass, and had a sacristy, living quarters and cemetery, with a length of 17 meters and almost 9 meters wide. The introduction of the railway affected the entire main square and the appearance of the temple, and in 1955 the original facade was covered; immediately afterwards a fence went up on the edge of the pavement and the temple remained isolated. In 1961 it was erected into a Vicariate and in 1965 it took on the shape it has today, after having created the façade and the door to the East; in 1976 he made it a parish.
