St. Peter Catholic Church, rich in beauty and tradition, is located in the historic downtown district of St. Charles, Missouri.  St. Peter Church is a short walking distance from Missouri's First Capitol and across the street from St. Joseph Health Center.  Since 1850, generations of Catholics have come to know Jesus Christ and his Church through its ongoing worship and service.

We welcome all visitors that come during the many religious and civic festivals.  We hope that these web pages will aid you in getting to know our parish and all it has to offer.

We look forward to seeing you at St. Peter.

Fr. John Seper - Pastor
