The Vascons settled in Aquitaine in the 6th century. It is likely that the village of Bascons owes its name to them. According to legend, Saint Amand, a Merovingian evangelist, performed miracles around 670, which led to the construction of a chapel near a well that attracted pilgrims seeking its healing waters. During the Middle Ages, Bascons served as the seat of the cour dels Sers, a court of justice for the Viscounty of Marsan, and the reputation of the fortified castle grew stronger. The Hundred Years' War and the Wars of Religion took a toll on the small town, causing it to lose its significance.
