This historic Spanish mission in the Tohono O'odham Nation Reservation is located 10 miles (16km) south of the city (a 20-minute drive) and was founded by Father Kino in the 1660s. The present church, a remarkable building, dates back to the 18th century and remains the oldest intact European structure in Arizona, housing a number of impressive artefacts and murals. It is a National Historic Landmark and is still an active place of worship, where visitors can attend services should they please - check the website for a service schedule and note that the church may be closed to sightseeing tourists during times of worship. The mission has a small museum, which showcases artefacts and multimedia presentations on the Mission's history.
