The Church of the Immaculate Conception of the Blessed Virgin Mary, also called St. Mary’s Basilica, is the oldest Catholic parish and the second oldest church in Phoenix. Between 1872 and 1881, Catholic priests from Florence, Arizona, would travel by buggy every three months to perform the liturgy. The building was constructed between 1902 and 1914, blending the Mission Revival and Spanish Colonial Revival architectural styles. It was officially dedicated in 1915 and replaced an earlier adobe church built in 1881 when the parish was founded. Starting in 1895, Franciscan Friars staffed the parish. Until 1924, it was the only Catholic parish in Phoenix. On September 6, 1976, the Arizona Historical Society named St. Mary’s an historic site. About a decade later, in 1985, Pope John Paul II elevated the church to a minor basilica.
