SULLY-SUR-LOIRE
Loiret — the fortress with water-filled moats
A medieval fortress from the end of the 14th century, with moats still full of water. It belonged to only three families until it passed, in 1962, to the département of Loiret. Joan of Arc was held here, Maximilien de Béthune, Duke of Sully and minister to Henri IV, lived here, and later Louis XIV and Voltaire took refuge in it. Inside, the medieval oak roof frame is the best reason to go in.
Municipal motorhome area (aire) on Chemin de la Salle Verte, right behind the château: about 35 places, with water and waste emptying, no electricity. The entrance is narrow, and in the front section, by the river, vehicles are limited to ~7.5 m. The published coordinates differ by almost 400 m: look for the area by name and address, not by GPS.

The château is a few hundred metres away, through the park that begins at the foot of the aire; the town centre is less than a kilometre away. A paved cycle path runs along the Loire: 11.5 km to the Romanesque basilica of Saint-Benoît-sur-Loire, from the 11th century.
