Within the walls of this museum, the romantic history of Missouri unfolds. The building is filled with treasures of historical significance dating from the era of the Louisiana Territory. Spacious rooms are filled with antique chandeliers, rosewood and mahogany chests and settees, French mirrors and fine paintings. This is the only county museum in the country to display inaugural gowns of its state's First Ladies at times throughout the year. The museum is closed December 15 - February 1.
