The beautiful Mission San Xavier del Bac, affectionately known as the "Dove of the Desert" was built during 1783-1794 under the guidance of Fathers Juan Bautista Velderrain and Juan Bautista Llorenz. An outstanding example of mission architecture, the labor used to build the church is believed to have been provided by the Tohono O'odham, on whose land the church resides.
The church is currently undergoing major restoration.
