Saint-Lizier
Saint-Lizier rises above the Salat, enclosed in part by walls inherited from antiquity. It was the seat of the bishops of Couserans, with churches in the upper town and the suburb below. Their chapters were united at Notre-Dame-de-la-Sède in the seventeenth century. The bishops also built a palace against the ancient walls, giving their mountain diocese a residence that overlooked the town and the valley.
