First Missouri State Capitol State Historic Site

200 South Main St., St. Charles, MO 63301 - United States




Located within a stone’s throw of the Missouri River and Katy Trail State Park, and in the heart of historic St. Charles, First Missouri State Capitol State Historic Site was the first seat of the state’s government. Its rough-hewn timbers and dark wood floors whisper the tales of the state’s first legislature. Interpretive programs help visitors understand how the state’s government was formed and what life was like in the early 1800s.


Free tours of Missouri's First State Capitol will highlight the day. Demonstrations of historic crafts will take place throughout the day. The last tour will begin at 3 p.m.

Participation in Museum Day is open to any tax-exempt or governmental museum or cultural venue on a voluntary basis.
