La Valenciana Church, Baroque church in Guanajuato, Mexico.

La Valenciana Church is a Baroque building in Guanajuato featuring walls of pale pink volcanic stone and three ornate altars covered in gold leaf. The structure follows a Latin cross plan and is topped with an octagonal dome.

The structure was built between 1775 and 1788 using wealth from the nearby La Valenciana silver mine controlled by Antonio de Ordóñez y Alcocer. This mining operation provided the resources needed for this major colonial religious project.

The church is a site of the Festival Internacional Cervantino. Its interior keeps original furnishings such as the pulpit with ivory and precious-wood inlays and the organ, plus 19th-century paintings by Luis Monroy. Sculptures of San Nicolás Tolentino, patron of miners, and San Ignacio de Loyola, patron of Guanajuato, are displayed.

The church stands on a hillside above Guanajuato on the highway to Dolores Hidalgo. The atrium is enclosed by a wall topped with merlons, and the remaining bell tower shows water damage and dust accumulation, so visitors should watch for uneven surfaces. The annex holds the University of Guanajuato archives.

The entrance is surrounded by a stone wall topped with crenellations, an architectural feature rarely seen on other colonial churches in Mexico. This fortified design gave the place a distinct character compared to other religious buildings from that era.
