Mission Basilica San Diego de Alcalá|
Mission Basilica San Diego de Alcalá was the first Franciscan mission in The Californias, a province of New Spain. Located in present-day San Diego, California, it was founded on July 16, 1769 by Spanish friar Junípero Serra in an area long inhabited by the Kumeyaay people. The mission and the surrounding area were named for the Catholic Didacus of Alcalá, a Spaniard more commonly known as San Diego. The mission was the site of the first Christian burial in Alta California. San Diego is also generally regarded as the site of the region's first public execution, in 1778. Father Luis Jayme, California's first Christian martyr, lies entombed beneath the chancel floor. The current church is the fifth to stand on this location. The Mission is a National Historic Landmark.
