Château de Castries has belonged to the House of Castries since 1465. In 1565, Jacques de Castries undertook the building of a new château. The garden was laid out by André Le Nôtre in 1666. The aqueduct, to water the garden, was built by Pierre-Paul Riquet.
The main house was looted and damaged during the French Revolution of 1789 and was restored in 1828. In 1935, it was bought back by René de La Croix de Castries. In 1985, he donated the house to the Académie française. It is open to the public.
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.
