Incorporated in 1809, St. Charles has distinguished itself as a historically significant city with a small-town feel. Located on the banks of the Missouri River, St. Charles has been called the "Williamsburg of the West." Repurposed buildings draw thousands of visitors each year, yet the city's historical importance is more than streets and structures. St. Charles was the scene of notable events, including the 1804 launching of Meriwether Lewis and William Clark's exploration of the Missouri River and land in the Louisiana Purchase. The first state capital was located here from 1821 until 1826. Pioneer Daniel Boone settled here and helped create Boone's Lick Trail. It became a major artery for settlers, leading to the development of the Santa Fe and Oregon Trails. In 1956, the first section of the Interstate Highway System opened in St. Charles.
