Most of the oldest buildings in the city are poteaux sur solle ("posts-on-a-sill"). One of the oldest structures is the Louis Bolduc House built in 1792, which has been designated as a National Historic Landmark. Louis Bolduc originally built a smaller house in 1770 at Ste. Genevieve's first riverfront location. Although much of the house was severely damaged by flooding, parts were dismantled and moved north as the community developed the new site in 1785. Bolduc incorporated these materials into his new and larger house, built in 1792–1793. The three large ground-floor rooms expressed Bolduc's wealth. Other structures of note are the 1806 La Maison de Guibourd Historic House, the 1818 Felix Vallé House State Historic Site, the 1792 Beauvais-Amoureux House, the 1790s Bequette-Ribault House, and the 1808 Old Louisiana Academy, all of which are listed on the National Register of Historic Places.
