By 1791, this town had 199 Spanish families, 7 mestizo families, and 19 mulatto families. The administration was managed by a secular council with an ordinary mayor and a procurador syndic, and its economy was based on agricultural production and pig farming, which were exported to mining areas, primarily Zacatecas.

A large part of the profits generated by agricultural activities in the town were invested by the inhabitants in the construction of a church, whose interior resembles the 19th-century churches of the region's haciendas. The church of Encarnación de Díaz has a sober façade, with notable three-tiered towers and domes. The ensemble is surrounded by an iron railing supported by rectangular quarry columns, with the finials holding lanterns.

The commercial importance of Encarnación de Díaz also allowed for the construction of a 19th-century cemetery that features neoclassical sculptural gems in its mausoleums. Inside a building with a central courtyard surrounded by arcades, there are embedded crypts that house the bodies of the community's inhabitants.
