St Louis Great Plains, USA Travel Guide
St. Louis occupies an unique place in the Midwestern United States. It sits on the western bank of the mighty Mississippi River, which forms the state border between Missouri and Illinois. This location, slightly south of where the equally powerful Missouri River flows into the Mississippi, grants St. Louis a distinct river city identity. The confluence of these two major waterways profoundly shaped the city’s development, establishing it as an important transportation and trade hub from its earliest days.
French fur traders founded the city in 1764, establishing it as a strategic trading post. The Louisiana Purchase in 1803 altered St. Louis’s destiny, marking it as the "Gateway to the West." Meriwether Lewis and William Clark chose St. Louis as their expedition's starting point in 1804.
The 19th century brought rapid growth, with the city becoming a bustling river port and later a major industrial and commercial center via railroads. St. Louis hosted the World's Fair and Olympic Games in 1904, showing its prosperity. The city continues its evolution, focusing on healthcare, biotechnology, and education.
