Château de Grand-Rullecourt was built in 1746 by Antoine-Constant de Hamel, next to the previous castle. After the French Revolution, the chateau was sold as a national asset, (Antoine's son having died on the scaffold). His grandson bought it back but couldn't afford to keep it. It later belonged to Captain Wallerand de Hauteclocque, who was killed during World War I. After the war, the property was sold in parts. Today the castle host a B&B.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
