Château d'Anjou is an 18th-century mansion located in Anjou, Isère, whose 10-hectare park was redesigned in the 19th century by renowned landscape architects Henri and Achille Duchêne, the celebrated gardeners of European princes and kings. The estate features meticulously composed themed gardens including a Florentine garden, French garden, shade garden, and romantic ruins—the Pâris ruins and Aphrodite grotto. Listed as a historic monument since 2009, the château preserves its grand interior with a wrought-iron staircase, chapel, dining room, and decorative basement murals. Positioned near the Château d'Albon across the Valloire river, this property exemplifies 19th-century Romantic landscape design.
