The mission is named for Louis IX, King of France (1215-1270). Because of its large size the mission has been nicknamed “King of the Missions.” The Indian name for the mission location was Tacayme. The mission is in the shape of a cross and the interior has double-dome wooden construction. The quadrangle contains the first pepper tree in California; the sunken gardens continue to be of interest. San Antonio de Pala is an asistencia to this mission. The Las Flores property is also claimed to be an asistencia.
The mission is in San Luis Rey, four miles East of Interstate 5 along California 76. Take 76 East from I5 and either stay on 76 until you reach Rancho del Oro in San Luis Rey or take Mission Avenue where it branches left outside San Luis Rey. Just North of 76, the mission is at 4050 Mission Avenue (California Landmark 239). (Make a note of Highway 76 if you wish to visit the asistencia to this mission. It is 19 miles further up HIghway 76 to Pala.)
