Exploring Fort de Chartres in Southern Illinois
We started this trip with the goal of visiting historic French forts along the Mississippi River, and this was our first stop on the Illinois side.
Getting here took a bit of planning since most routes require heading north or south before cutting back west. But the drive gave us a chance to enjoy a lot of the Illinois countryside along the way.
What Is Fort de Chartres State Historic Site?
Located just a few miles west of Prairie du Rocher, this site marks the location of the last and most impressive of four French forts built in the region.
Originally constructed in wood beginning in 1720, the final version of the fort was rebuilt in stone in 1753.
Fort de Chartres served as:
- The center of French government in the Illinois Country
- The main military installation in Upper Louisiana
- A key stronghold until it was taken over by the British in 1765
Today, it stands as one of the best-preserved examples of French colonial architecture in the Midwest.
First Impressions of the Fort
When we arrived, the first thing that stood out was the size of the fort.
After parking, there’s a short walk along a flat gravel path leading up to the main gate. As you approach, the structure really does resemble a small stone castle—with high walls, watchtowers, and a double-gated entrance.
It’s not what most people expect when they think of forts in this part of the country.
Walking Through the Grounds
Once inside, you can explore the open courtyard and the buildings that line the interior walls.
Some structures have been fully restored, while others show different stages of construction, giving you a better understanding of how the fort was originally built.
From the elevated areas above the gate, you can really get a sense of the scale and layout of the entire fort.
We also learned that Lewis and Clark passed through the area and noted the ruins of the fort during their journey in 1803.
A Unique Piece of Midwest History
This is one of those places that really stands out because it’s so different.
When most people think of forts in the Midwest, they picture wooden stockades—but Fort de Chartres is a massive stone structure, which makes it rare for this region.
It gives you a completely different perspective on early colonial history along the Mississippi River.
Events and Visiting Information
The site hosts a variety of events throughout the year, including historical reenactments and educational programs.
There’s also a picnic area where you can relax and enjoy the surroundings after exploring the fort.
Things to Know Before You Go
- Large parking area available
