Mission San Xavier del Bac
Founded in 1692 by Father Eusebio Kino, the church of San Xavier Mission was constructed from 1783 to 1797, making it the oldest intact European building in Arizona. The mission is a gorgeous example of Spanish Colonial architecture, from its Baroque facade to the brightly painted wood carvings that decorate the transept and altar. Restorations after an earthquake in 1887, a lightning strike in 1939, and leaking walls in 1989 have allowed the church to continue serving the community to present day.
