A short history
French fur traders founded St. Louis in 1764 near the meeting of the Mississippi and Missouri rivers, and nearby Cahokia was once the largest Native city north of Mexico. After the Louisiana Purchase in 1803, Lewis and Clark set off from here, and the city became the gateway for westward expansion. German immigrants built its breweries, and the 1904 World's Fair was held in Forest Park. The Gateway Arch, finished in 1965, honors the city's role in the westward movement.
