The fortress is actually three castles in one, strung along a limestone ridge above the town: the Fort Saint-Georges, the Château du Milieu (the main residence), and the Fort du Coudray. Most of what stands today dates from the reign of Henry II of England, who made Chinon one of his primary strongholds and died here in 1189 — reportedly on hearing that his son Richard had joined the rebellion against him.
The Logis Royal has been converted into a thoughtful museum covering both the Plantagenet era and Joan of Arc's visit, with good use of the original spaces. The Tour du Coudray, where Joan stayed during her time in Chinon, also held the last Grand Master of the Knights Templar, Jacques de Molay, imprisoned here in 1307. The Clock Tower at the entrance houses additional Joan of Arc exhibits.
The views from the ramparts over the Vienne valley are excellent. Allow two hours at minimum.
