“The king of missions!”Founded in 1798 by Padre Fermin Francisco de Lasuen, the Mission was named after St. Louis IX, King of France, who lived during the 13th century. The history of the San Luis Rey area reflects five periods of occupation: Luiseno Indian, Spanish Mission, Mexican Secularization, American Military, and Twentieth Century Restoration.
