Mission San Luis Rey de Francia is one of the 21 California missions founded by Spanish Franciscan missionaries. Established in 1798, it is located in Oceanside, California and is named after Saint Louis of France. The mission served as a center for agriculture and education, helping to spread Christianity among the local Native American population. The mission features a beautiful church, gardens, and historic buildings that reflect the Spanish colonial architecture. Today, it is a popular tourist destination and a site for cultural events, preserving the history of the mission and its role in California's early development.
