About the book: 2018 / When the royal decree prohibited lords from having citadels capable of withstanding a siege, the owner of the castle did not demolish the keep and cut windows in the walls. He removed the gate and filled in the ditch. Since then, the former fortress has been called Port Ouvert - Castle of the Open Gates. So why was this ridiculous stronghold with its gates removed and a ditch filled in for a hundred years never taken by anyone??
