Armand IV d’Alegre became Baron of Allegre in 1343, but in 1361, Arnaud attacked the chateau. Armand IV was killed during the siege by Thomas de La Marche, and his widow, Alix de Chalençon, remained in Alegre. But, in 1364, her nephew, Bertrand de Saint-Nectaire, claimed the inheritance, and hunted Alix from the fortress. Alix de Chalençon asked John I de Berry to regain the castle, and after 6 months of siege, Alix regained her property. The brother-in-law of the Duc de Berry, John II de Armagnac, now provides custody.
Following the death of Alix de Chaleçon, the Duc de Berry donated the barony of Allègre to Morinot de Tourzel in 1385. Morinot de Tourzel undertook repairs and construction of the enclosure wall using plans drawn up by the architect Hugues Aubriot, architect of the Bastille. These efforts were pursued by his son Yves I, who focused on beautifying the castle. This castle, with its 23 towers, was one of the most beautiful and most significant in the region.
In November 1698, while Yves V de Tourzel came from Versailles to Allègre, a great wind excites the fire that snores in the chimney of the high hall. A fire is declared and spread in the abundant frames of slate-covered roofs. At the sound of the bells, five hundred people run and make the chain. But in less than five hours the castle is ablaze. But it is not abandoned. From January 1699, Yves V made the Commons “repaired” and then the castle itself. His son-in-law will continue the work. In vain, the castle was not recovered from the catastrophe.
