Brézé sits on top of a network of subterranean rooms and passages (1.5km of them open to the public) that include a boulangerie, wine cellars, defensive bastions and a troglodyte dwelling dating from at least the time of the Norman invasions (early 10th century). Above ground, much of the U-shaped château dates from the 19th century, as do the many intricately painted neo-Gothic and neo-Renaissance interiors.
Don't miss the top floor of the West Tower, used in the 1800s as quarters for lower-ranking servants. The only way to see six rooms in the private Renaissance wing is to take a two-hour tour (reserve ahead; French only). The dry moat is the deepest (15m to 18m) in Europe that completely encircles a castle. All signs are in English. Situated 12km south of Saumur.
