The Catholic Church in Hancock County, Illinois, has a long history, much like the county itself. Though some of our earlier parishes have come and gone, our current churches in Nauvoo, Carthage, Dallas City, Warsaw, and Hamilton remain alive and well. We are glad for your visit to our website and hope that it will offer you a glimpse into Catholic life in the far west of Illinois. Of course, we hope that you’ll take the opportunity to visit us in person someday.
Immaculate Conception Church
Carthage’s first Catholic church, dedicated to the Immaculate Conception, was built in 1875, and the parish’s first resident priest came in 1878. The current Church was completed in 1914 and has undergone various renovations since. Immaculate Conception Catholic Church currently serves 150 families.
Sacred Heart Church
Dallas City, IL
Dallas City did not have its own church building until 1908, when four zealous Catholic families pushed for and were granted their own parish dedicated to the Sacred Heart. Today Sacred Heart is a mission of Sts. Peter and Paul and serves 110 families.
Sacred Heart Church
As early as 1849, Catholic families had settled in Warsaw. The current church was erected in 1874. Sacred Heart currently serves 50 families.
St. Mary Church
The Catholics of the Hamilton area met in a farm building at Eleventh and Walnut Streets, beginning in 1869. In 1880 a small frame house was deeded to the bishop of Peoria, it was remodeled, and it served as the church until 1956 when the current church was built. St. Mary’s is currently a mission of Sacred Heart in Warsaw, and it serves 50 families.
Sts. Peter and Paul Church
Though the town of Nauvoo is known for an important period in the history of Mormonism, it has strong Catholic roots that endure to today. Today Catholics still worship in the same church begun in 1867 and they have great pride in their pre-k – 6th grade school. Sts. Peter and Paul serves 240 families.
