St. Charles, Missouri
Missouri became a US state in 1821. The government decided to build a new state capital, the "City of Jefferson", in the center of the state on the Missouri River. A temporary capital was needed, and St. Charles beat eight other cities in a competition to be the temporary capitol. It offered free meeting space for the legislature in rooms above a hardware store.  This building is preserved as the First Missouri State Capitol State Historic Site. It is open to tourists. The Missouri government met there until Jefferson City was ready in 1826.
