Travel back to Missouri’s early French roots at Felix Vallé House State Historic Site. The American-Federal style Vallé house was built in 1818 and today is furnished in the style of the 1830s with a host of artifacts that show the American influence on the French community of Ste. Genevieve after the Louisiana Purchase. The Green Tree Tavern, the oldest verified vertical log building in Ste. Genevieve, is also managed by the historic site and can be toured.
