Mission San Xavier & Arizona-Sonora Desert Museum
A day combining the finest Spanish colonial mission church in the United States with the desert natural history museum that is widely considered one of the best institutions of its kind in the world. Mission San Xavier del Bac — 'the White Dove of the Desert' — was completed in 1797 by Franciscan padres under Father Juan Bautista Llorenz, and is still an active parish serving the Tohono O'odham Nation on whose land it stands. The church's white-plastered walls, Moorish towers, and Baroque interior ornament (gilded altarpieces, polychrome statuary) represent the highest achievement of colonial Spanish architecture in what is now the United States. The Arizona-Sonora Desert Museum 9 miles outside Tucson is an outdoor zoo, botanical garden, natural history museum, and art gallery in one open-air institution covering the entire Sonoran Desert region — featuring 300 animal species and 1,200 plant species native to the Sonoran Desert in naturalistic enclosures set in the actual desert.
