Excavations at The San Agustín Mission, Weeks 1 and 2

Excavations began at the San Agustin Mission site on November 20, 2000, and concluded in Feburary of 2001. The mission site, although heavily disturbed, is still providing important evidence about Tucson's Origins. In April of 2007, archaeologists have returned to the mission site in preparation for the construction of the Tucson Origins Heritage Park.

San Agustin Compound Wall

Prior to the beginning of fieldwork at the site, only a few rocks from the west compound wall were visible.

You can move your mouse over this image to reveal the wall foundation below the modern ground surface.

Stone Foundation to San Agustin Mission Compound Wall

These stones represent the foundation of an adobe brick wall wall that once surrounded the mission. These foundation stones or "footers" provided a platform for the adobe bricks to be stacked upon, keeping the adobe bricks above ground level. Excavations have revealed that the stone foundation of the wall survives for at least 30 meters (92 ft) along the east side of Brickyard Lane.

foundation of the San Agustin granary.

Backhoe stripping has also uncovered the foundation of the granary, used to store crops during the occupation of the mission. The granary is about 18 meters long and 9 meters wide. Because of the width of the structure, and the lack of long timbers, a series of pillars ran down the center of the building. These pillars helped support ceiling timbers, each perhaps 4.5 meters long.

Unfortunately, it was discovered that the majority of the mission area was destroyed in the 1950s during clay mining and landfilling activities. Red lines on the above map represent backhoe trenches revealing modern garbage, sometimes to a depth of 4.5 meters (20 feet).

Attempts to find the chapel and convento were thwarted by the depth of disturbed areas- it appears that the remains of these structures were bulldozed between 1956 and 1960. South of Mission Lane a 50 to 60 ft wide band of undisturbed soil remains. Excavation of test units and limited backhoe scraping have exposed a Hohokam pithouse, a fragmentary structure foundation- perhaps from the Carrillo House, a probable acequia (canal), and a pit filled with trash discarded by Chinese farmers who lived in the area between 1880 and 1900.

A rusting wok, at least one hundred years old, provides evidence of Tucson's Chinese Heritage.
