3. The Gateway Arch that defines the skyline of St. Louis, Missouri, represents so much more than the city itself. St. Louis was the last major stop on the banks of the Mississippi before many settlers headed west into the frontier during the 19 th century. In fact, 110 years ago today, Lewis and Clark began their monumental expedition into the Louisiana Purchase by departing from the St. Louis area, bidding farewell to the city’s comforts, such as they were then, to blaze a trail of westward expansion.
