The Château de Hattonchâtel site was fortified in 860 by Hatto, Bishop of Verdun, whose name it bears, on a rocky promontory overlooking the Woëvre flat land. The settlement became the chief stronghold of the bishops and also the location of their mint until 1546. In 1636 the retreating Swedes besieged and burnt most of the town.
The medieval castle was destroyed during World War I in 1918. The site was entirely reconstructed between 1923 and 1928 by Henri Jacquelin, a Norman architect originally from Evreux, in the Neo-Renaissance style. He produced the ultimate 'troubadour' château of Lorraine, a pastiche which used some remains from the 11th century building. The work was financed by the American benefactor Belle Skinner.
The Château de Hattonchâtel has been listed as a monument historique by the French Ministry of Culture since 1986 and is privately owned. The château is run as a hotel, wedding and conference centre.
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.
