The San Antonio de Pala Asistencia, or the "Pala Mission", was founded on June 13, 1816 as an asistencia or "sub-mission" to Mission San Luis Rey de Francia, some twenty miles inland upstream from the latter mission on the San Luis Rey River. Pala Mission was part of the Spanish missions, asistencias, and estancias system in Las Californias—Alta California. Today it is located in the Pala Indian Reservation located in northern San Diego County, with the official name of Mission San Antonio de Pala. It is the only historic mission facility still serving a Mission Indian tribe.
