Since the settling of St. Charles as Les Petites Cotes (the little hills) by Louis Blanchette in 1769, the riverfront area has been important to the commercial and social growth of the city. Today it is a vibrant example of historic preservation. Yet, in the 1960s, the area was endangered as the once-lovely buildings deteriorated. Thanks to the efforts of dedicated citizens prompted by the restoration of the first state capitol property, the area underwent a revitalization and rebirth. The Main Street Historic District was placed on the National Register of Historic Places in June 1970.
