Pere Marquette State Park, the largest in Illinois, commemorates the beginning of European exploration of the rich Illinois country and its subsequent settlement and development. The Illinois and Potawatomi Indians were occupying the area of the park when Pere Marquette, along with Louis Jolliet and five other companions, passed by in the fall of 1673. At the confluence of the Illinois and Mississippi Rivers is located a large, plain cross in honor of Pere Marquette's party. The park provides extensive accommodations for visitors, including a lodge and guesthouses, a nature museum, and interesting roadways. - NPS
