Fort de Chartres State Historic Site

Fort de Chartres is the most significant French colonial site in the American Midwest. The original fort was built of wood in 1720; the present stone structure — partially reconstructed to its 1750s appearance — was built between 1753 and 1756 at great expense by the French crown to assert control over the Illinois Country and the Mississippi Valley trade routes.

The site today includes the reconstructed gateway and powder magazine (the only surviving original structure), a museum with exhibits on French colonial life and military history, and interpretive panels throughout the grounds. The scale of the fort is striking for the remote setting — this was a serious military installation, designed to hold several hundred soldiers, built with limestone quarried from nearby bluffs.

The Illinois Department of Natural Resources manages the site; it is open Wednesday through Sunday. An annual rendezvous event in late spring draws re-enactors from across the region and gives the fort a rare sense of life and activity.

A story
Fort de Chartres was the seat of French government for the entire Illinois Country — a territory stretching from the Great Lakes to the Gulf of Mexico. When France ceded its North American lands to Britain in 1763 after the Seven Years' War, this fort was the last post in the Mississippi Valley to be handed over, finally surrendered on 10 October 1765. The delay was not reluctance but logistics: word traveled slowly, and the French garrison simply hadn't received the news.
