St. Charles Historic District
The St. Charles Historic District is a national historic district located at St. Charles, St. Charles County, Missouri. It is the site of the first permanent European settlement on the Missouri River and of the embarkation of Lewis and Clark's journey of exploration along the Missouri. The first state capital of Missouri and over one hundred other historic buildings are located in the district. The district was listed on the National Register of Historic Places in 1970, including 63 contributing buildings over a 47-acre (19 ha) area. The district was later increased three times.
