The Ducey domain came into the hands of the old Norman Montgommery family in 1521 after the wedding of James Montgommery to Claude de la Boissière, the heiress to the lands of Ducey. The castle was built at the beginning of the 17th century by Gabriel II de Montgommery, one of the sons of Montgommery first who became famous for killing Henry II, king of France, by accident in a tournament on 30th June 1559. He converted to Protestantism and became one of the greatest Protestant Chiefs in the area. Gabriel caused the hatred of Catherine de Medicis and was beheaded on the Place des Grèves on 26 th June 1574. Gabriel II de Montgommery was born in 1565 an inherited the lands of Ducey. Following his father's example, he became the chief of the Protestants in the Avranches area.
Today Château des Montgommery is 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.
