The History of St. Patrick Church dates back to 1838 with the arrival of the Reverend John Francis Plunkett, from Dublin, Ireland, who came in answer to the call of the dying canal workers during the malaria epidemic of 1838. Father Plunkett was appointed the first pastor of the future St. Patrick Church by Bishop Simon Brute of Vincennes, Indiana.
With the building of the I & M Canal, many immigrant families had come to the area, most of whom were Catholic and many came from the Emerald Isle. As the community grew, Father Plunkett began construction of a new stone church on Broadway Street just west of the Canal and south of Jefferson Street. Thus was born St. Patrick Church, the oldest Roman Catholic Church in the Diocese of Joliet and the second oldest in the whole Metropolitan Chicago area. It is now considered a landmark of Joliet.
During the next seven pastors and seventy-seven years, St. Patrick Church continued to grow and see many changes. Once its name was changed to St. George. However, after eight years it reverted back to the original name St. Patrick. From County Tipperary, Ireland, came Reverend Philip L. Kennedy in 1917. He was assigned to erect a new St. Patrick Church, School, and Rectory. The first mass was offered in the new church on Sunday, March 2, 1919. The site for this new church was 710 West Marion, the present site of St. Patrick Church.
St. Patrick is now fortunate to have Reverend Father Peter Jankowski as pastor. Through his spirituality, humor and grace, St. Patrick will continue to be a very close and loving community. Many priests have been assigned as pastor to St. Patrick Church. All of these men have given of their talents and spiritual leadership:
