The Ministère de la Culture's notice

La tour (de l'ancien château, aujourd'hui ruiné) avait une fonction à la fois défensive et résidentielle. Elle a été construite autour de 1100 en blocs de calcaire. Cette tour est maintes fois citée dans les ouvrages consacrés à l'architecture militaire du Moyen Age.
