Saint Junípero Serra Ferrer, popularly known simply as Junipero Serra, was a Spanish Catholic priest and missionary of the Franciscan Order. He is credited with establishing the Franciscan Missions in the Sierra Gorda, a UNESCO World Heritage Site. He founded a mission in Baja California and established eight of the 21 Spanish missions in California from San Diego to San Francisco, in what was then Spanish-occupied Alta California in the Province of Las Californias, New Spain.
