About St. Charles, MO

Saint Charles (commonly abbreviated St. Charles) is a city in, and the county seat of, St. Charles County, Missouri, United States. The population was 70,493 at the 2020 census, making St. Charles the eighth-most populous city in Missouri. Situated on the Missouri River near its mouth at the Mississippi, St. Charles is a northwestern suburb of St. Louis. The city was founded circa 1769 as Les Petites Côtes, or "The Little Hills" in French, by Louis Blanchette, a French-Canadian fur trader. The St. Charles area was settled primarily by French-speaking colonists from Canada in its early days. This former French territory west of the Mississippi River was nominally ruled by Spain following France's defeat in the Seven Years' War, while France had also ceded the east of the Mississippi to Great Britain. St. Charles is thus the third-oldest city in what is now the state of Missouri. In the 18th and 19th century, the city's waterfront played a significant role as a river port for westward trade and expansion, including trade with Native American tribes on the upper Missouri River. In 1804 the Lewis and Clark Expedition considered this settlement the last "civilized" stop before they headed upriver to explore the western territory that the United States acquired from France in the Louisiana Purchase. The city served as the first Missouri capital from 1821 to 1826. It was also the starting point of the Boone's Lick Road to the Boonslick and the Santa Fe Trail. In the 20th century, it became the site of the Saint Rose Philippine Duchesne Catholic shrine.
