Today, visit three of the most important castles in the area. Start with the jewel of the French Renaissance, Château CHAMBORD. Next is the 16th-century Château of Catherine de Medici, lovely CHENONCEAU, a fairytale castle with a moat, drawbridge, and towers. In Amboise, visit CLOS LUCÉ, where Leonardo da Vinci worked and lived during the last part of his life, and marvel at an amazing collection of models of his inventions, like his design of an airplane, painstakingly reconstructed from the drawings of the great renaissance genius.
