History+
The origins of the Château d'Aubenas date back to the 11th century, with the keep attributed to this early period. The complex, once completely surrounded by a moat, was rebuilt and expanded multiple times. The original core castle developed into a fortress, whose round towers and battlements are almost entirely equipped with machicolations. These structural changes contributed to the Château d'Aubenas acquiring its current form and being classified as a Monument historique in 1943.
