Mission San Xavier del Bac

Mission San Xavier del Bac stands nine miles south of Tucson, Arizona, on the Tohono O'odham San Xavier District reservation and is widely regarded as the outstanding example of Spanish Colonial Baroque architecture in the United States. The original mission was established in 1692 by Jesuit missionary Father Eusebio Francisco Kino, who visited the Pima settlement of Bac on the Santa Cruz River and laid the groundwork for a permanent Christian community. After the Jesuit expulsion from Spanish territories in 1767, Franciscan missionaries took over and constructed the present church between 1783 and 1797, employing Tohono O'odham labor under the direction of Franciscan fathers. The exterior, built of fired brick and lime mortar and finished in white-painted plaster, features twin bell towers of which only the eastern tower was completed, lending the structure its characteristic asymmetry. The richly ornamented facade combines Moorish, Byzantine, and Mexican Baroque decorative elements in a composition unique in North American mission architecture. The interior is equally elaborate, with painted frescoes covering the walls and vaulted ceiling, gilded altar screens framing polychrome wooden sculptures, and a central retablo depicting saints and biblical narratives restored during a major conservation effort carried out in the 1990s with support from the Getty Conservation Institute. A side chapel in the east transept houses a recumbent figure of St. Francis Xavier venerated as a miracle-working image by Tohono O'odham pilgrims, who bring offerings of milagros and attend an annual pilgrimage each autumn. The mission continues to serve as an active parish, with daily masses celebrated in a church that has maintained continuous liturgical use for more than two centuries. A small hilltop mortuary chapel across the highway from the main complex dates to the same period and offers a panoramic view of the Santa Cruz River valley and the Sonoran Desert landscape surrounding the mission.
