It was used as the administrative center for the province, which was part of New France. Due generally to river flooding, the fort was rebuilt twice, the last time in limestone in the 1750s in the era of French colonial control over Louisiana and the Illinois Country.\nThe magazine (ammunition storehouse) of the fort is believed to be the oldest surviving building in Illinois. A partial reconstruction now exists of the limestone fort and the site is preserved as an Illinois state park, four miles (6 km) west of Prairie du Rocher in Randolph County, Illinois.
