Château de Rochecotte, a late 18th century château, is known for its various owners and their many successive rebuilds. Originally, the château belonged to the comte de Rochecotte, who became one of the leaders of the second Chouannerie in Maine and was executed under the French Directory.
On 30 April 1828, one of the later owners, the chevalier René de La Selle de Ligné, sold it to Dorothée de Courlande, duchess of Dino, for 400,000 francs, then a considerable sum. Today Rochecotte serves as a 4-star hotel.
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.
