Built for Diane de Poitiers by Philibert de l'Orme with the treasury of her royal lover Henri II — a manifesto of French Renaissance classicism stamped everywhere with crescents and interlaced initials. Partly demolished after the Revolution, what survives (entrance, chapel, one wing, and Diane's funerary chapel) is of the first importance.
