Located four miles west of Prairie du Rocher, Illinois, the site marks the location of the last of four successive French forts named “de Chartres.”
Built in 1753 by the French during their eighteenth-century colonization of the Illinois Country, the massive stone fort was preceded by three wooden forts, with the first fort erected in 1720. Fort de Chartres served as the French seat of government and its chief military installation in Upper Louisiana from 1753 until 1765 when it was occupied by the British.
In 1763, France ceded much of its territory in North America, including what is now Illinois, to Great Britain. British troops occupied the fort from 1765 until 1772, when encroachment by the Mississippi River caused a collapse of the south wall. Subsequently, the remaining walls and buildings fell into ruin.
Today, the site features an imaginative reconstruction of portions of the fourth Fort de Chartres. The fort gate, built in the 1920s, has been remodeled several times. Portions of the fort’s walls were reconstructed on original foundations in 1989. The site was declared a National Historic Landmark in 1960 and was added to the National Register of Historic Places in 1976.
