History of St. Joseph Church Prairie du Rocher Illinois
St. Joseph Church in Prairie du Rocher, Illinois, was established in 1722 as a chapel linked to the church of Ste. Anne at Fort Chartres. Following the founding of Fort Chartres in 1718 by Pierre Duque Boisbriant, the local community built a log chapel for the French settlers. Over time, the church gained prominence as Ste. Anne fell into disrepair, becoming a key parish for the French in the region. The current Romanesque church structure dates from 1858, embodying the parish’s rich history and cultural heritage.
