Santa María del Agua de Landa mission, Franciscan mission in Landa de Matamoros, Mexico.

The mission in Landa de Matamoros is a religious building with an ornately decorated stone facade in Churrigueresque style, incorporating local artistic features. The grounds include multiple structures and open spaces that form a complete religious center from the 18th century.

Founded on 29 April 1744 by the Franciscans José de Escandón and Pedro Pérez Mezquima, it was the last of the five Franciscan missions in the Sierra Gorda. The church and convent were built between 1761 and 1770, with Miguel de la Campa supervising from 1761 to 1764. UNESCO listed it in 2003 as part of the Sierra Gorda missions, and restoration began in July 2022.

The name Landa comes from Chichimeca Jonaz and means "marsh"; the mission is consecrated to the Immaculate Conception of Mary. On the facade, look for the Archangel Michael in a feathered headdress, shown victorious over a demon, a figure the Franciscans used to represent the evangelisation of the Sierra Gorda.

The mission stands in the town of Landa de Matamoros, in the Sierra Gorda of Querétaro. The compound is entered through an atrium with a sacramental door, an open chapel and posa chapels, so allow time to walk between the church and the cloister. Restoration work on the complex began in July 2022, so some areas may be closed off.

The facade's top statue shows the Archangel Michael in a feathered headdress, victorious over a demon. It was placed as a symbol of the Franciscan missions' success in evangelizing the Sierra Gorda. The first body of the facade also pairs Franciscan saints with the founders of the Dominican Order, who had evangelized the region earlier.
