    Mission Santa Inés (Ynez) was a Spanish mission in the present-day city of Solvang, CA., and named after St. Agnes of Rome. Founded on September 17, 1804, by Father Estévan Tapís of the Franciscan order, the mission site was chosen as a midway point between Mission Santa Barbara and Mission La Purísima Concepción, and was designed to relieve overcrowding at those two missions and to serve the Indians living north of the Coast Range. The mission was home to the first learning institution in Alta California[5] and today serves as a museum as well as a parish church of the Archdiocese of Los Angeles. It is also designated a National Historic Landmark, noted as one of the best-preserved of the 21 California missions.
