Castelnau-de-Vaux, which was destroyed in 1214, was succeeded by the fortified town of Castelnau-Montratier, built on the promontory c 1250. The wool and cloth markets made this a lively place. The former Place du Mercadial (today Gambetta), a square with lime and chestnut trees, is a pleasant spot. Meanwhile, the church, Église St Martin, at the end of the promontory, calls to mind Paris's Sacré-Coeur. Three windmills, one of which is written about as early as 1400, stand to the north.
