Château de Robert-le-Diable, Medieval castle ruin in Moulineaux, France.
The Château de Robert-le-Diable is a medieval castle ruin perched on a hilltop overlooking the River Seine near Moulineaux. Its remaining stone walls and towers display architectural features from Norman military construction spanning several centuries.
King John of England built the castle in the early 13th century before King Philip II of France gained control and ordered its reconstruction. Local inhabitants deliberately damaged its towers during the Hundred Years' War to prevent English forces from using it as a military stronghold.
The castle's name comes from Robert the Devil, a legendary Norman knight whose folklore still shapes local identity and draws visitors curious about regional legends. The place remains a symbol of Norman storytelling traditions that survive in the surrounding community.
The castle sits roughly 20 minutes from Rouen with free access to its grounds and multiple walking trails through surrounding forests. Wear sturdy shoes for exploring the paths, especially during wetter months when the terrain can be muddy.
The River Seine once flowed directly beneath the castle walls, providing natural defense and access to trade routes used by successive rulers. This location made the site strategically valuable for controlling regional commerce and movement.
