Fort LeHillier Marker

    Fort LeHillier is an anglicized version of the original name, Fort L'Huilier, founded by French explorer Pierre Charles le Sueur (the namesake Le Sueur County).  The fort was built atop a large natural mound and consisted of three or four log cabins surrounded by a palisade.  Le Sueur chose the area south of what is now Mankato for the blue clay that gives the county its name, thinking it was valuable copper ore.  It was found to be worthless after Le Sueur transported two tons of it back to France, after which the fort was abandoned.  Cultivation has since destroyed any evidence of the fort's existence, though the natural mound is still clearly visible.
