Château de Courtanvaux was originally built in the 14th century. It was enlarged and restored in 1450-1490. The Renaissance style appearance was built by Souvré family who owned castle between 1500-1661 and current Neo-gothic style restoration took place in the 19th century. The chateau was owned by three families until 1978.
Today there is 68 hectares of park around the chateau. The park is open to the public and the castle in summer season.
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.
