192 S. Stone Ave., Tucson
Facing Stone Avenue, St. Augustine Cathedral, dedicated to Tucson ’s patron saint, was built in 1896 and remodeled several times over the years. The facade has stone-carved yucca, saguaro, and horned-toad flourishes, and there are statues of the Virgin Mary and the titular saint near the big heavy-wood entrance.
Catholics or anyone interested in regional variations on the Mass may want to attend the lively mariachi mass at 8 a.m. every Sunday. Inside, one of the bells formerly used in the Spanish-era cathedral is preserved in the vestibule.
