To establish the Prairie du Rocher French Colonial National Historical Park in the State of Illinois, and for other purposes.

HR 5558 would establish the Prairie du Rocher French Colonial National Historical Park in Illinois to preserve and interpret key sites of French colonial history. The park would include Fort de Chartres (a National Historic Landmark), the Creole House, the ASC Convent (built 1876), the Pierre Menard Home, and the Kolmer Site, recognizing the area's multi-ethnic community and contributions of enslaved Africans, Native Americans, and religious groups like the Adorers of the Blood of Christ. It aims to provide educational programs about the region's French colonial heritage and support preservation efforts for these historic properties. The National Park Service would manage the park under standard national park system guidelines.
