The name was changed in 1759, to honor of Claud Louis d'Espinchal, Marquis de Massiac, the French Naval Minister.
In 1778, during the American Revolutionary War, Colonel George Rogers Clark led his regiment of "Long Knives" into Illinois near the site of the fort at Massac Creek.

A visitor center just north of the reconstruction includes a museum with Indian artifacts, mannequins in period clothing, and other exhibits that explain the history of the fort.
