The Bauvais-Amoureux House Overlooking le Grand Champ—those communal fields that once sustained entire village harvests—the Bauvais-Amoureux House rises from Missouri earth with quiet architectural courage. Built around 1792 by Jean Baptiste St. Gemme Beauvais, this rare structure speaks through its most distinctive feature: poteaux-en-terre construction, in which upright cedar logs are set directly into ground itself, as if determined to anchor French memory into frontier soil. Hand-hewn timbers form a Norman truss system beneath a steeply-pitched roof echoing early French Canadian farmhouses. Here, in this marriage of Old World tradition and New World necessity, stands one of the few surviving examples across the United States of this ancient building technique. A Woman’s Story: Pelagie Amoureux Benjamin Amoureux purchased this house in 1852, claiming it as his own. When he died, his wife Pelagie inherited it—becoming keeper of its stories, guardian of what endures when buildings outlast their builders. Her story, long latent, was recently uncovered by a remarkable serendipity: a long-lost relative living in California discovered connections to Pelagie and fought to ensure her voice reached across time. Academy Award-winning Breakwater Studios created a short film about Pelagie’s life, part of a new resource library allowing descendants of enslaved peoples Read more…

Green Tree Tavern Standing across from the famed locus of Jour de Fête in downtown Sainte Geneviève, the Green Tree Tavern is Missouri’s oldest verified building—scientifically dated to 1790 through dendrochronology—and far more than historic architecture. This French colonial structure represents a living chronicle of American frontier life, cultural convergence, and the diverse, often uncomfortable truths that shaped westward expansion. Built by Nicolas Janis, a French Canadian immigrant from Kaskaskia, Illinois, using vertical log construction (poteau sur sole), the building has served as family home, gathering place, inn, tobacco shop, and meeting hall for the first Masonic Lodge west of the Mississippi River. Now part of Ste. Genevieve National Historical Park, Green Tree Tavern offers visitors a tangible connection to the complex, layered history of America’s heartland. Free guided tours are available through the Welcome Center, where rangers share stories of the people who lived and worked within these walls—including those who were enslaved and whose resilience and determination deserve equal prominence in the building’s history. 1790: The Oldest Standing Building in Missouri The scientific dating matters. Using dendrochronology—analyzing tree rings to establish precise construction dates—researchers confirmed Green Tree Tavern’s 1790 construction with certainty other historic buildings can rarely achieve.

Jean-Baptiste Vallé House – Ste. Genevieve National Historical Park Standing as one of the most architecturally significant and historically important structures in Ste. Genevieve, the Jean-Baptiste Vallé House represents both the architectural sophistication of French Creole building traditions and the political power that once resided in this Mississippi River community. Now part of the Ste. Genevieve National Historical Park and operated by the National Park Service, this imposing residence tells the story of colonial governance, architectural evolution, and the dedicated preservation efforts that saved it for future generations. Architectural Significance: Poteaux-sur-Solle at Its Finest The Jean-Baptiste Vallé House stands as a large and impressive example of “poteaux-sur-solle” (post on sill) construction—one of the distinctive French Creole building methods that make Ste. Genevieve architecturally unique in the United States. Unlike the rarer “poteaux-en-terre” (posts in earth) construction where vertical logs are set directly into the ground, the poteaux-sur-solle method places vertical log posts on a horizontal wooden sill beam that rests on a stone foundation. This elevation above ground level protects the wooden posts from moisture and rot, resulting in far greater durability—which explains why this particular house has survived for more than two centuries. The house’s size alone commands attention. Read more…

Ste. Genevieve Welcome Center At 66 South Main Street in the heart of downtown Ste. Genevieve, the Welcome Center serves as the essential first stop for visitors exploring America’s oldest settlement west of the Mississippi River and the gateway to Ste. Geneviève National Historical Park. Currently operated by the City and transitioning to National Park Service ownership, it functions as both tourism hub and official park visitor center, providing everything you need to understand and navigate what makes Ste. Genevieve remarkable. The centerpiece is Lewis Pruneau’s magnificent 12-foot by 12-foot diorama depicting Ste. Genevieve as it appeared in 1832—meticulously researched by resident historian Jim Baker and hand-crafted by internationally acclaimed diorama builder Pruneau, who Sheperd Paine (arguably the best-known figure in the genre) once called “the Cecil B. DeMille of diorama builders.” The gift shop stocks excellent selections of Ste. Genevieve merchandise, books, maps, and National Park Service materials. Knowledgeable NPS Rangers staff the center, a Junior Ranger program welcomes families, and admission is completely free. One visitor summed it up perfectly: “Fantastic National Park Service visitor center. Rangers are excellent, very friendly, helpful, and nice. Lots to do and see. Very lovely community.” Lewis Pruneau’s 1832 Diorama: The Crown Read more…
