During this period , wood clapboard siding was applied to the original adobe chapel walls as both a cosmetic and a protective measure ; the veneer was later removed when the Mission was restored . During the 1906 San Francisco earthquake , the adjacent brick church was destroyed . By contrast , the original adobe Mission , though damaged , remained in relatively good condition . However , the ensuing fire touched off by the earthquake reached almost to the Mission 's doorstep . To prevent the spread of flames , the Convent and School of Notre Dame across the street was dynamited by firefighters ; nevertheless , nearly all the blocks east of Dolores Street and north of 20th street were consumed by flames . In 1913 , construction began on a new church ( now known as the Mission Dolores Basilica ) adjacent to the Mission , which was completed in 1918 . This structure was further remodeled in 1926 with churrigueresque ornamentation inspired by the Panama-California Exposition held in San Diego 's Balboa Park . A sensitive restoration of the original adobe Mission was undertaken in 1917 by architect Willis Polk . In 1952 , San Francisco Archbishop John J. Mitty announced that Pope Pius XII had elevated Mission Dolores to the status of a Minor Basilica . This was the first designation of a basilica west of the Mississippi and the fifth basilica named in the United States . Today , the larger , newer church is called " Mission Dolores Basilica " while the original adobe structure retains the name of Mission Dolores
