San Miguel is home to the Mission San Miguel Arcángel, founded on 25 July 1797. Mission San Miguel Arcángel was founded on July 25, 1797 by the Franciscan order, on a site chosen specifically due to the large number of Salinan Indians that inhabited the area, whom the Spanish priests wanted to evangelize. It is located at 775 Mission Street, San Miguel, California, in San Luis Obispo County.
The mission remains in use as a parish church to this day. After being closed to the public for six years due to the 2003 San Simeon Earthquake, the church re-opened on December 22, 2009. Inside the church are murals by Esteban Munras. Father Presidente Fermin Francisco de Lasuen founded the mission on July 25, 1797, making it the sixteenth California mission. Its location between Mission San Luis Obispo and Mission San Antonio de Padua provided a stop on the trip that had previously taken two days.
