In 1884, the Grundy Center parish purchased two lots at the east edge of town. Erection of a church started to become a reality in 1885 as supporters hauled sand and rock by team from Steamboat Rock.

Father Patrick Hogan was appointed resident pastor for the Catholics in Grundy Center and the Murphy Settlement in 1896.

The windows depict the lives of twelve saints: St. John the Apostle, St. Jerome, St. Martin, St. William, St. Vincent DePaul, St. Lawrence, St. Henry, St. Peter, St. Agnes, St. Catherine of Sienna, St. Veronica and St. Michael.
