Castelnau-de-Lévis is a commune in the Tarn department in southern France. It is located just west of Albi. The inhabitants are Castellévisiens. The castel was built at the beginning of the thirteenth century by Gicard Alamon, and called Castelnau de Bonnafonds. It was rebuilt by the Lévis in the fifteenth century, when the seigneurie came into the possession of Hugues d' Amboise, baron d'Aubijoux; the fief remained with his descendants until the seventeenth century.
Hugues' grandson, Louis d'Amboise, comte d'Aubijoux and baron de Castelnau-de Bonnafous, restored the château and dwelt in it. The narrow square watchtower (tour de guet) is 40m tall.
