Discover more about Fort de Chartres State Historic Site

Fort de Chartres State Historic Site, located near Prairie du Rocher, Illinois, marks the location of the last of three French forts named "de Chartres". Built in the 1750s, this impressive stone structure served as the French seat of government and its chief military installation in the Illinois Country. Today, visitors can explore the reconstructed fort, including portions of the walls, several stone buildings, and the powder magazine, believed to be the oldest building in Illinois. Originally constructed to protect French interests in the region and control the local Native American population, the fort played a vital role in the economic and administrative life of the Illinois Country. The site features an imaginative reconstruction of portions of the third Fort de Chartres, offering visitors a tangible connection to the past. Inside the fort, you'll find the restored powder magazine, reconstructed stone buildings, and exposed foundations of other buildings. A museum and office building, built in 1928 on the foundation of an original fort building, houses exhibits depicting French life at Fort de Chartres. The fort was surrendered to the British in 1763 following the Treaty of Paris. However, by 1772, the Mississippi River encroached upon the fort, causing the south wall to collapse and leading to its eventual abandonment. The State of Illinois acquired the ruins in 1913, recognizing its historical significance. Today, the site hosts various events throughout the year, including the Fort de Chartres Rendezvous, French and Indian War Assemblage, and Winter Rendezvous, offering visitors a taste of colonial-era life.
