Although in Gallo-Roman times, a Roman road ran to the south of "Aigrefeuille", no evidence of human occupation of this time was noted there. It was not until the period of the High Middle Ages that the first traces can be found. This Roman road was called "Le Grand Chemin" (The Great Way) and is well documented in the Table of Peutinger and archaeological excavations connected "Angériacum" to the current "Saint-Jean d'Angely", which is the presumed site of the "Port du Plomb" at L'Houmeau via Muron and Le Thou.
