Felix Vallé House State Historic Site is composed of several buildings that preserve and interpret notable examples of the architecture and history for which the community is widely known. The Felix Vallé House, built in 1818, was designed as a combination mercantile store and residence for its original owner, Jacob Philipson. Built of native limestone, its Federal-style architecture demonstrates the American influence on the community in the decades following the Louisiana Purchase. The home was sold to the prominent Vallé family of Ste. Genevieve in 1824 and served as a location for the trading firm of Menard & Vallé, as well as the residence of Felix and Odile Vallé.
