Assume that a Gallo-Roman village replaced the huts of the Gallic tribes.
During the Gallo-Roman Period Lavaridin was called Lavbicinum. The ruined foundations of its Roman-era fort still overlook the Loir Valley below. It is not surprising that the Roman invaders wanted to occupy this strategic point of the Loir Valley. The foundations of a temple dedicated to the Roman God Mercury was found on the promontory adjoining the chateau. It is believed that a Gallo-Roman village replaced the huts of the Gallic tribes of the area. Lavardin was on the old Roman road between Vannes and Orleans and it was probably the place of intersection of the road from Blois to these towns. Old Roman paving stones are still used today as supports for the steel bridge leading to Montoire. It took five centuries for latin influence and religion to seep into Celtic culture but, little by little, all of France became Christain. Saint Julien, the first bishop of LeMans, visited Lavardin in the third century.
