Eastern Pyrenees

South of Comminges, the Pyrenean valleys of Couserans descend towards the Salat and its tributary the Lez. The Col de la Core links the upper Salat country with the Castillonnais valley. In 1513 representatives of Saint-Lizier, Saint-Girons and the neighbouring valleys met at Fos to renew agreements between communities on opposite sides of the central Pyrenees. Farther downstream, the bishops of Couserans held Saint-Lizier above the Salat, where a medieval bridge crossed the river.
