Fur trader Pierre Laclede established St Louis as a French trading post in 1764, settling at the confluence of the Mississippi and Missouri Rivers. It proved an ideal location, subsequently becoming a major port as well as a main departure point for explorers travelling the westbound wagon trails.
St Louis became a manufacturing centre for everything a pioneer would need on his journeys, such as saddles and guns, and it was here that explorers Lewis and Clark stocked up with provisions for their now famous expedition.
Today, St Louis is a modern, commercial, industrial, and cultural centre. It operates as the biggest city in Missouri and one of the largest inland ports in the country. Reminders of St Louis's frontier history are evident most visibly in the shining steel Gateway, the famous landmark dedicated to the pioneers of the Western Frontier.
The city has numerous personalities, existing as a mix of authentic America with a vaguely European air. Music from the nation's past floats from famous jazz and blues clubs, while paddle steamers dock along a riverfront filled with antique shops and restaurants now part of the revitalised Laclede's Landing Historic District.
Within the riverside park known as the Jefferson National Expansion Memorial, the Gateway Arch is a soaring landmark above the city's skyline. The thin stainless steel arc reaches to twice the height of the Statue of Liberty, at 630 feet (192m) tall.
It symbolises the role of St Louis as the 'Gateway to the West' for the pioneers who journeyed along the Oregon and Santa Fe Trails towards the western frontier. It is also dedicated to the US president who was responsible for opening up the West.
An observation deck reached by a tram system provides magnificent views over the city, the Mississippi and the spreading plains. Also on the site with the Arch is the Old Courthouse Museum, the venue for the hearing of several momentous cases during the 19th century.
At the base of the monument is the excellent Museum of Westward Expansion, with exhibits covering exploration of the West and its honoured pioneers, including Lewis and Clark, the Plains Indians, and buffalo soldiers. The Odyssey IMAX Theatre shows big-screen films about the region and its history.
Larger than New York's Central Park, the beautifully landscaped Forest Park is filled with attractions. The acclaimed St Louis Art Museum has a magnificent international collection of art covering works from the prehistoric to the contemporary, housing one of the most extensive collections of German Expressionism worldwide.
The St Louis Science Center features life-size dinosaurs along with displays and interactive exhibits on the environment, aviation, technology and more. There is also an OMNIMAX Theatre and Planetarium.
Thousands of animals roam the beautiful grounds of the St Louis Zoo, with indoor and outdoor displays, and a Living World Exhibition features an animated robotic figure of Charles Darwin who summarises his theories on evolution.
The Missouri History Museum documents life in St Louis with old photographs and displays on river life, local music, and western expansion. Forest Park is brimming with natural beauty and fun diversions for the whole family and can easily occupy visitors for hours.
