On Sunday, July 16, 1769, Fathers Junipero Serra, Juan Viscaino, and Fernando Parron raised and blessed a cross to establish Alta California’s 1st Mission. Relocated from Presidio Hill to this site in August 1774, the mission was the mother of those founded in California by the Franciscan Order. The present buildings, first completed in 1813, were rebuilt in stages from 1915 to 1931 after many years of deterioration. They have been in use as a parish church since February 1941.
