The Château de Troussay is one of the smallest Châteaux of the Loire Valley. The first building is recorded around 1450, although the oldest existing parts of the structure date from the Renaissance.
In the 17th century, the building was enlarged with a central body and two wings. A magnificent formal French-style garden was laid out behind.
Today the chateau is privately owned but open to the public.
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.
