Roofing at the crossroads: timber procurement for historical roof construction at the confluence of two major waterways in Occitania (France)

Le résumé fourni par la source

Research on historical roof structures and timber supply networks in southwestern France remains scarce. Combining archival sources and epigraphic evidence with dendrochronological data, we examined three roofs located at the confluence of the Garonne and Tarn rivers to better understand timber procurement in modern-period Occitania (France). We identified two distinct systems: a long-distance supply for fir (Abies alba Mill.) and a local one for oak (Quercus sp.). In the 17th and 18th centuries, rafting was the main transport method, while the 19th century shows changes in long-distance procurement methods and possibly supply regions. Our research highlights the need to refine fir tree-ring chronologies to strengthen future provenance studies.
