The Château de Lassay is a 15th-century castle in Lassay-les-Châteaux. The first mention of a castrum in Lassay dates back to the 12th century. Owned by Charles de Vendôme at the beginning of the 15th century, the castle was destroyed by French troops as Charles de Vendôme supported the English during the Hundred Years War.
In 1458, the French king Charles VII allowed the son of Charles de Vendôme, Jean II, to rebuild a castle. The new castle was achieved within one year. The barbican was built in 1497-1498.
Since then, the castle has been left mainly intact and the original 15th-century architecture preserved by the different owners of the castle.
The castle is listed as a Monument historique since 1862. It is open for visiting from April to September.
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.
