A magnetometer survey undertaken by ISAS at the location of the third Fort de Chartres, a circa 1730 wooden fortification, and its associated French settlement has revealed new insights into the built environment of the French colonial capital of the Illinois Country. Magnetometry data revealed previously unknown lines of paired posts and trench walls outside the fort’s walls and new information about the fort’s internal structure. At Chartres village, foundation trenches, cellars, fence or property lines, and an abandoned roadbed were evident in the data, offering data into the physical structure of a French settlement largely lost to the river.
