From Wikipedia: The Mission San Gabriel Arcángel is a fully functioning Roman Catholic mission and a historic landmark in San Gabriel, California. The settlement was founded by Spaniards of the Franciscan order on “The Feast of the Birth of Mary,” September 8, 1771, as the fourth of what would become 21Spanish missions in California.[10] San Gabriel Arcángel, named after the Archangel Gabriel and often referred to as the “Godmother of the Pueblo of Los Angeles”,[11] was designed byAntonio Cruzado, who hailed from Córdoba, Spain. Cruzado gave the building its strong Moorish architectural influence. The capped buttresses and the tall, narrow windows are unique among the missions of the California chain. (accessed 2018)
