Owners and admirers of these residencies reveal them to us in this film. Chambord is the largest of them. The former hunting lodge of Beauregard is a more secluded residency, and houses an astonishing portrait gallery. Straddling the river Cher, Chenonceau is also known as the "Castle of Ladies ", in reference to its successive female residents – Diane de Poitiers and Catherine de Médicis. The Garden of Love and the Garden of Music enchant visitors at Villandry. And finally, Brézé houses Europe's largest underground fortress.
