About St. Joseph · Prairie Du Rocher, Illinois
St. Joseph Catholic Parish in Prairie du Rocher, Illinois, is one of the oldest Catholic communities in the American Midwest, established in 1722 as a chapel dependent upon the royally endowed church of Ste. Anne at Fort Chartres. It is the only truly French-founded parish in the Diocese of Belleville and stands as a living monument of French colonial presence in the Mississippi Valley. The current church building, a Romanesque-style structure with a distinctive flat ceiling inspired by the basilicas of Rome, was cornerstoned on July 19, 1858. Today the parish is part of the Parish Partnership of Chester, Ellis Grove, and Prairie du Rocher and serves the small historic French village of Prairie du Rocher.

Why belong here
St. Joseph offers a historically rooted Catholic faith community in the heart of one of America's oldest French-settled villages, with weekend Masses alternating between Saturday evening and Sunday morning throughout the year. The parish is part of the Parish Partnership of Chester, Ellis Grove, and Prairie du Rocher, which extends pastoral care across three historic communities and offers shared devotions such as a monthly Mass of Healing and Eucharistic Adoration (first Monday of the month at 7:00 pm). It is a small, closely-knit congregation where worship is centered in the Eucharist, neighborly service is a lived value, and parishioners care for one another through Prayer Shawl Ministry, a Parish Council, Finance Council, and care of the historic St. Joseph and St. Leo Cemeteries.

History of St. Joseph Parish
Established in 1722 as a chapel under the royal church of Ste. Anne at Fort Chartres, St. Joseph is the only truly French-founded parish in the Diocese of Belleville. Two Jesuit priests, Father Le Boullenger and Father De Beaubois, originally served the French families around the fort from the church in the village of Nouvelle Chartres. When settlers moved to higher ground at the foot of the rock bluffs, Jean St. Therese Langlois — nephew of Fort Chartres commandant Pierre Duque Boisbriant — received a land grant and founded 'La Belle Prairie du Rocher,' where a log chapel was built in what is today the original parish cemetery. In 1734 it was replaced by a larger log church.
The Bourbon Era, the British Surrender, and the Sacred Vessels of Ste. Anne
In 1765 Fort Chartres — the last place in America to fly the Bourbon flag of France — surrendered to the British, ending French rule in the Mississippi Valley. The royal church of Ste. Anne fell into disrepair, but St. Joseph Chapel survived and took its place as the parish church of the area. In 1767 the records and sacred vessels of Ste. Anne were transferred to St. Joseph at Prairie du Rocher, and after a civil suit in the British court they were returned once more to Prairie du Rocher for safekeeping — where, the parish says, they remain to this day and are 'the marvel and admiration of historians.'
- Fort Chartres surrendered to the British in 1765
- Records and sacred vessels of Ste. Anne transferred to St. Joseph in 1767
- St. Joseph described as 'the only living monument of the French power in Mid America'
The Present Church Building (1858)
The current Romanesque church was inspired by the basilicas of Rome. After two Prairie du Rocher residents returned from the Holy Year of 1850 and agitated for a new church, foundations were laid beside the old log church. The great flood of 1851 surrounded the site and forced the builders to abandon the foundations and rebuild at a higher spot that has never again been flooded. The corner stone was laid July 19, 1858, and the resulting flat-ceilinged Romanesque interior is a direct echo of the great churches of Rome.
- Romanesque style with flat ceiling, modeled on the basilicas of Rome
- Cornerstone laid July 19, 1858
- Relocated after the 1851 Mississippi flood
