St. Catherine's is a mission church of St. Joseph's and is located in Hornitos, California. It was built during the 1860's probably in 1865.
Before the church was built, priests came from Stockton to say Mass for the people of Hornitos. Priests from Sonora and Mariposa came for Mass after the church was built. In the 1930s the church was repaired, adding a rock foundation and rock buttresses to make the church firm and solid again.
Every year on All Soul's Day (November 2), people from St. Joseph's parish community and many others gather for the annual candlelight procession and blessing of graves, gathering at the Hornitos Plaza where the procession begins at 6:00pm. After the procession, a Mass for the Dead is celebrated in St. Catherine's.
