In 1324 the Castle of l'Estriverie estate was declared a fief by the Counts of Hainaut and granted to Gérard de Lestruve. The estate was passed on to Hoste d'Ecaussinnes and in 1440 to the Despretz de Quievrain family who kept it until 1483. One of this family, Watier de Quivrains, erected a castle here in 1454. It is on the foundations of this old castle that the current building stands.
In 1483 the estate passed by marriage to the Cottrel family, who kept the castle for seven generations. This family did most of the restoring and rebuilding in the 16th and 17th century, and turned the fortified medieval dwelling into a graceful château.
In 1727, the estate became the property of Marie Spinola, the last niece of the Cottrel family. She gave it to her son, who sold the estate in 1756 to Joseph Antoine de Wautier. The court of Hainault however overturned the sale and transferred the castle to Jean Philippe d'Yve, Viscount of Bavay.
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.
