Les Rochers was the estate of the Mathefelon family from the 12th century, before being passed by marriage to the Sévigné family in 1410. The family rebuilt the château in the early 16th century. Between 1644 and 1690, Madame de Sévigné stayed here and refurnished the house. She gave names to the paths through the gardens and in 1689 her son commis-sioned the French Gardens from Le Nôtre. In 1715, the Nétumières family bought the estate and carried out building and restoration works. Today there is a visitor centre at the 17th century Orangerie and exhibition about Madame de Sévigné and the Château des Rochers.
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.
