Santa Cruz Catholic Church, Catholic church in Tucson, United States

Santa Cruz Catholic Church is a long rectangular basilica designed by Bishop Henry Granjon in the Spanish Colonial Revival style with Islamic nuances, including a minaret-like bell tower. Its walls are covered in white paint and plaster, and a parapet with decorated perforations and baroque finials surrounds the roof. A rectangular skylight on the western side lights the altar, while a continuous choir loft above the eastern entryway compresses the entrance before opening into the tall nave.

Bishop Henry Granjon designed the church, built 1916–1918 by Manuel G. Flores. On November 11, 1918, Granjon heard of Germany's surrender, ran to the tower and rang the bells for the first time, announcing Armistice Day. The church was dedicated in February 1919. In November 1924, striking Mexican copper miners set off dynamite inside, damaging trusses and blowing off the front door; repaired trusses still limit choir loft use.

The name Santa Cruz means "Holy Cross" in Spanish. The church was dedicated in February 1919, a few months after its bells first rang on November 11, 1918, when Bishop Henry Granjon climbed the tower to announce the Armistice. The building follows a long rectangular basilica plan with a Convento around a courtyard.

The church stands at 1220 S. Sixth Avenue, near the Santa Cruz River, south of downtown Tucson. It is an active parish, so visits fit around Mass times. The choir loft holds only a limited number of people at once, a restriction kept since the 1924 dynamite blast damaged the trusses.

The church is the largest known mud-adobe building in Arizona and the state's only surviving major public building made of adobe. Its bricks were made on the Tohono O'odham Indian Reservation and laid unstabilized, without the asphalt or cement added to modern adobe. The building joined the National Register of Historic Places in 1994.
