Our next stop, south of Tucson about 20 miles, was the Mission San Xavier del Bac - The White Dove of the Desert - is a blindlingly white adobe building rising from the sere brown landscape of the desert. Built between 1783 and 1797, it incorporates Moorish, Byzantime and Mexican Renaissance achitectural styles. The church was never actually completed - you can see this when you look at the 2 bell towers - one is topped with a dome while the other has none. In recent years, the church has undergone an extensive renovation and it is beautiful. The interior is spectacular with paintings on plaster that are gorgeous.
