Father Angel Somera and Father Pedro Cambon, both Franciscan missionaries, founded the original Mission San Gabriel Arcángel, called Mission Vieja, on September 8, 1771; the location is today near the intersection of San Gabriel Boulevard and the Rio Hondo River. The establishment of the mission marked the beginning of the Los Angeles region's settlement by Spaniards and the fourth of twenty-one missions ultimately established along California's El Camino Real. The mission did well initially as a farm and cattle ranch. Six years after its founding, however, a destructive flood led the mission fathers to relocate the establishment farther north, to its current location in what is the present day city of San Gabriel. The original mission site is now memorialized as California Historical Landmark #161.
