Welcome to the Fort de Chartres State Historic Site!


Please note: Fort de Chartres State Historic Site is now re-open to the public after months of closure due to the closing of the Prairie du Rocher flood gates and area flooding. We welcome visitors return to the site and look forward to our Fall Special Events at Fort de Chartres! For more information about scheduled Special Events, please view the event information at the bottom of this page or visit the event page of this website or our Facebook Special Events listings.

We thank the Levee Commissioners, federal, state and local governments and agencies, and area residents and businesses for their hard work protecting this historic area.


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.

Inside the fort are the restored powder magazine, believed to be the oldest building in Illinois, two reconstructed stone buildings, and the exposed foundations of other buildings. The powder magazine is stocked with reproduction barrels and barrel racks. A combination museum and office building, built in 1928 on the foundation of an original fort building, houses exhibits depicting the history of Fort de Chartres and the Illinois Country. The large stone Guard House, reconstructed in 1936, contains a Catholic chapel furnished in the style of the 1750s, along with a priest’s room, a gunner’s room, an officer-of-the-day room, and a guard’s room. Also on the grounds are an operating bake oven, a garden shed built of upright logs in post-on-sill construction, and a kitchen garden with raised beds of produce that would have been grown in eighteenth-century Illinois.

Recreational facilities outside the reproduced fort include a day-use area with a picnic shelter and grills.

Fort de Chartres welcomes you to the heart of French Colonial Illinois! Please visit us throughout the year, whether for a wonderful day trip through the hills of southwestern Illinois or at one of our many special events held throughout the year.

Special Event-100th Anniversary of Fort de Chartres State Park

Saturday, October 5, 2019
10 AM-4 PM


Saturday’s event activities include a re-dedication ceremony of the original bronze plaque being presented to the State. Other event activities will feature 1920s era music, an antique automobile demonstration, a collection of vintage material, photos and documents from the first 100 years of the park’s history will be on display, with some reenactors dressed in early 20th century era clothing.

There were efforts to purchase and restore the site of Fort de Chartres as early as 1911, but the property wasn’t purchased by the State of Illinois until the years of 1914 and 1915, recorded in two separate transactions. Work was undertaken in following years to prepare the site for public use and the best documented date for the site’s official opening as a State Park is October, 1919. At that time, a bronze plaque was dedicated and placed on the powder magazine.

Please join us in celebrating this important event in the preservation of the history of Fort de Chartres State Historic Site.

WR poster design by Mitch Lopata, Lopata Design

This event features 18th and early 19th century camp life and re-enactors who participate in a muzzleloader woods walk shooting competition.

Fort de Chartres State Historic Site presents a weekend of colorful clothing, hand-made crafts, period music and delicious food when the annual Winter Rendezvous returns November 2 & 3.

Soldiers, trappers, traders and Native Americans (as portrayed by historic re-enactors) will gather at the rendezvous. They’ll trade goods, buy supplies, and some will take part in a shooting contest that requires them to walk through the woods and fire flintlocks at pop-up targets.

The rendezvous is fun both for the participants demonstrating frontier life from 1700 to1820 and for visitors spending an autumn day wandering among the tents, campfires and historic French colonial fort. The event is open and free to the general public.   This event is hosted by Les Coureurs des Bois de Fort de Chartres and sponsored by Les Amis du Fort de Chartres. Please check the Winter Rendezvous page of this website for an event flyer and participant event rules information.
