In 1873, Eugène Viollet-le-Duc built a bell tower typical of the style of northern France on top of the donjon of the building. It was in this donjon that Jean Calas, a Protestant victim of a religiously-biased trial, was interrogated. Only the Henri IV courtyard and gate survive from the original medieval buildings.
