The quick answer
Mission San Xavier del Bac (Spanish: La Misión de San Xavier del Bac) is a historic Spanish Catholic mission about 10 miles (16 km) south of downtown Tucson, Arizona, on the Tohono O'odham Nation San Xavier Indian Reservation. The mission was founded in 1692 by Eusebio Kino in the center of a centuries-old settlement of the Sobaipuri O'odham, a branch of the Akimel or River O'odham located along the banks of the Santa Cruz River. The mission was named for Francis Xavier, co-founder of the Jesuit Order in Europe. The original church was built to the north of the later Franciscan church and was demolished during an Apache raid in 1770.
How it came to be
The mission was rebuilt between 1783 and 1797, which makes it the oldest European structure in Arizona. Labor was provided by the O'odham. An outstanding example of Spanish Colonial architecture in the United States, the Mission San Xavier del Bac hosts some 200,000 visitors each year. It is a well-known pilgrimage site, with thousands visiting each year on foot and on horseback, some among ceremonial cavalcades or cabalgatas.
The detail most people miss
The site is also known as "Wa:k" in the O'odham language (O'odham: Wa:k ("Water Place") referring to its surface water and springs, which no longer flow. The water in the Santa Cruz River came up to the surface a few miles south of Martinez Hill and then submerged again near Los Reales Wash. The Santa Cruz River used to run year-round in this section and was once critical to the community's survival, but now runs only part of the year.
Why it still matters
Mission San Xavier del Bac was established in 1692 by Eusebio Francisco Kino, who founded a chain of Spanish missions in the Sonoran Desert. A Jesuit of Italian descent, Kino often visited and preached in the area, then the Pimería Alta colonial territory of the Viceroyalty of New Spain. Construction of the first mission church, about 2 miles (3 km) from the site of today's mission, began on April 28, 1700, as noted in his diary:
Look closer
On the twenty-eighth we began the foundations of a very large and capacious church and house of San Xavier del Bac, all of the many people working with much pleasure and zeal, some in digging for the foundations, others in hauling many and very good stones of tezontle from a little hill which was about a quarter of a league away. ... On the twenty-ninth we continued laying the foundations of the church and of the house.
