French-Canadian colonists established Ste. Geneviève in 1735 when the land west of the Mississippi was part of French Louisiana. It was the first permanent European settlement in Missouri. In 1785 the river flooded, and the town relocated three miles away on higher ground.
I visited Ste. Geneviève with the National Park Traveler’s club during the 2022 convention in St. Louis. We watched the park film and toured the Jean Baptiste Vallé House across the street from the visitor center. Then we followed the ranger across town to the Green Tree Tavern for the final stop on the tour.
The area passed into Spanish control with the Treaty of Fontainebleau in 1762. Spain returned the Louisiana Territory to France in 1800. Citizenship changed once again with the Louisiana purchase in 1803. The ranger giving our group’s tour asked how we would feel if one day we woke up and our home was in a different country. Because of this history, Ste. Geneviève had a unique blended culture.
The French used distinctive construction methods known as Poteaux-en-terre and Poteaux-sur-sol. These translate to “post in ground” and “post on sill.” The walls use vertical, instead of horizontal, logs placed directly into a trench in the ground or on a sill. These walls are topped off with large timbers to create a steeply pitched roof.
This design had some advantages. The vertical logs stood up better to the earthquakes that hit the area in the early 1800s. And the large attic space was used to store hay in the winter, providing insulation. By the time the weather warmed up, the hay had been fed to the livestock opening up the attic for ventilation.
Ste. Geneviève is home to most of the remaining examples of this type of architecture. The National Park Service designated the village a National Historic District in 1960. The district achieved National Historical Park status in 2020.
Green Tree Tavern➤
Green Tree Tavern is the oldest building still standing in Ste. Genevieve and one of the few where you can see the vertical logs that form the structure. The Janis family migrated from Illinois to Ste. Genevieve around 1789. They built the Green Tree Tavern and it served as their home and business for 40 years. Over the course of its history, the home functioned as a tavern, an inn, a tobacco shop, and a Masonic Lodge.
