The early Catholic voyagers and missionaries visited many parts of Minnesota now under the jurisdiction of the Bishop of Winona. In 1660 Groseiliers and Radisson made a visit to the Prairie Sioux in southern or south-western Minnesota. There are, however, no definite records showing what route they took or how far they travelled; in all probability they followed the course of the Minnesota River. In 1680 Father Louis Hennepin, OFM, accompanied by Antoine Augelle and Michael Accault, set out from Fort Creve-coeur to explore the Upper Mississippi. On the Minnesota shore, the territory which they passed on the journey from La Crescent to Lake City now belongs to the Diocese of Winona. In 1683 Nicholas Perrot established a trading-post at or near the site of the present city of Wabasha. With him was the Jesuit Father Joseph Jean Marest (here) (here) who laboured as a missionary among the Sioux Indians.
