The San Agustín Mission

One of the first images of Tucson and the San Agustín Mission
U. S. Border Commissioner John Bartlett came to Tucson, Sonora in 1852, on a mission to determine the future border between the United States and Mexico. Bartlett spent much of his time in recording his impressions of the area, exploring and making drawings. He climbed Sentinel Peak on the 17th of July, 1852 and made the first detailed sketch of the community (Bartlett 1854:295-296).
The Site:  The San Agustín mission was located south of Congress Street and immediately east of Mission Road. The area was first occupied during the Early Agricultural period at least 2,600 years ago, with a number of pithouses found on or to the west of the mission. Hohokam artifacts are abundant in the area, suggesting a substantial village was present between 1,500 and 500 years ago. Father Kino documented a Pima village in the area in the 1690s.

History:  The San Agustín Mission was established in the mid-1700s and was completed in the late-1790s to early-1800s. The Mission included the convento (a two-story preist's residence and trade school), a chapel, a granary and other outbuildings, all surrounded by a wall. Nearby were the mission gardens and a Pima village. The mission was abandoned by the 1840s with the chapel falling down sometime between 1862 and 1876, but the convento remained in relatively good condition until the late 1890s. By the 1940s however, clay mining had encroached upon the mission and in the 1950s the City of Tucson used the area as a dump.

Archaeology:  Excavations on the mission site were conducted by Desert Archaeology Inc. as part of the Rio Nuevo project in the Fall of1999 and winter of 2000.  The excavations were design to determine the integrity of the mission site and to provide information to urban planners in the design of the Tucson Origins Heritage Park. Unfortunatly, excavations found that much of the mission site had been lost to a variety of processe that damaged the site. Research utilizing historical inference and 3d computer modeling was then used to demonstrate that enough historic evidence was avalaible to allow accurate reconstructions of the mission's convento and granary.
