Historic Sites

Visitors are welcomed to explore the site of the most important French fortification in Illinois. Built in the 1750's, Fort de Chartres served as France's headquarters in the Illinois Country.

Fort de Chartres State Historic Site holds many popular annual events. An annual two day Rendezvous is held the first weekend in June, features shooting competitions, military drills, dancing, music, food, and traders of eighteenth-century style goods. The first weekend in October marks the site's French and Indian War Assemblage, a living history event that portrays life during the time period of 1754-1763. The area's rich farmland produced much of the grain that fed towns on the lower Mississippi River. France surrendered Fort de Chartres to the British in 1763 under the Treaty of Paris.
