The Early Renaissance French Château de Vallery, in Vallery, in the département of Yonne in the Burgundy region of France, was built in 1548 for Jacques d'Albon de Saint-André, marquis de Fronsac, a court favorite of Henri II and maréchal de France. It was never completed, and what remains of it have been mutilated. The site he chose was the ancient château-fort of Vallery, dating in part to the early thirteenth century; he purchased it 16 April 1548. The architect was the king's architect, Pierre Lescot, who also built the hôtel particulier of the Maréchal in Paris (demolished).
