St. Louis: The Historic Gateway to the West

Known affectionately as "The Lou" or the "Gateway to the West," St. Louis is a prominent independent city in Missouri. Founded on February 14, 1764, and named after Louis IX of France, the city has evolved from a strategic river outpost into a major American urban center. Its unique status as an independent city means it operates separately from any surrounding county.

The city's identity is inextricably linked to its geography, sitting along the banks of the Mississippi River, which served as the primary artery for westward expansion in the United States.
