There was a Gallo-Roman villa on the site of Château de Chassay already in the 6th century AD. The castle is mentioned in the 1096 in a bishop letter. The current château was built in the 16th century. King Henry IV visited there in 1598. The castle was abandoned from the French Revolution until 1827, when it was acquired by Countess de Bondy. Today it is owned by the municipality.
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.
