Le Crumbling Château de l'Herm, Abandoned Since the 17th Century, Notorious

The decaying Château de l'Herm, hidden in the Nouvelle-Aquitaine region of France, once served as the residence of Jean de Calvimont, a man of power and influence, who was not just a member of the Bordeaux parliament but also acted as Francis I's envoy to Spain. This grand 16th-century fortress, crafted between 1500 and 1520, has been deserted since 1605. However, some remnants, like its ancient moats, still manage to token its existence. This veritable relic was woven into the plot of Eric Le Roy's 1899 work, Jacquou le Croquant. The narrative unfolds in this actual location, many real place names being incorporated, and tells the tale of a peasant rebellion against the malevolent counts who inhabited the Château de l'Herm.
