Its position on the seafront overlooking the cliffs promises a relaxing time for all nature lovers. The site has an interesting history in that it holds a small place in legend. Der-Écu means strong shield, a name that originates from the battle fought by William the Conqueror, Duke of Normandy and future King of England. An enemy threatened to cut off William’s head with his ax. A Norman knight, Richard le Fort, interposed his shield and the ax went deep into the wood of the shield without breaking it. William’s life was saved and the Strong Shield became a legend and reminds us that this castle was meant to defend Normandy against attackers.
