Château de Bonnemare was built to the site of medieval manor in the mid-1500s by Nicolas Leconte. Later it has been owned among others by Étienne de Fieux (1637), Cromelin de Villette family (18th century), Charles Le Blond, and Gustave Gatine (1888), the predecessor of current owners.
The castle consists of main building, gatehouse and Renaissance chapel from the 16th century. Today Bonnemare is a hotel. The notable detail is a kitchen, where is a roasting spit designed by Leonardo da Vinci.
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.
