History
Tumacácori National Historical Park preserves the ruins of three Spanish colonial mission communities in the upper Santa Cruz River valley of Santa Cruz County, southern Arizona, north of the international line with Sonora. The principal unit is the mission of San José de Tumacácori, whose surviving church was begun by Franciscan missionaries in the late eighteenth century and substantially built through the first decades of the nineteenth. The mission's founding as a Jesuit visita reaches back to 1691, when Eusebio Francisco Kino first visited the O'odham settlement at the site, and the long arc of mission activity at Tumacácori extends across the entire Spanish and early Mexican period of the Pimería Alta.
Construction at the surviving church is fired brick, stuccoed adobe, and rubble masonry combined in the manner characteristic of late Spanish Colonial work in the northern frontier provinces: a single-aisle nave with sanctuary and apse, an attached convento and walled cemetery, and the unfinished bell tower whose stepped silhouette anchors the surviving image of the site. The companion mission ruins of Guevavi and Calabazas, also within the park, survive principally as adobe wall stubs and foundation lines, the typical surface condition of abandoned northern Sonoran adobe construction exposed to a century and more of weathering.
The Tumacácori mission was abandoned in the mid-nineteenth century after Apache pressure and political reorganization following Mexican independence and the Gadsden Purchase. The site was set aside as Tumacácori National Monument in 1908 and redesignated Tumacácori National Historical Park in 1990 when the Guevavi and Calabazas units were added.
The park today operates as a National Park Service museum and interpretive unit, open to the public on a regular schedule. Within Arizona's adobe tradition Tumacácori is among the most significant surviving witnesses to the Spanish Colonial mission architecture from which the Sonoran adobe inheritance of southern Arizona descends.
