Château de Launac was built by the viscounts of Gimoes in the 12th century. In 1148 the castle passed into the house of Isle Jourdain. Dismantled after the Treaty of Paris in 1229, the fortress was rebuilt in the fifteenth century by Carmaing Nègrepelisse. It consisted of four corner towers including an old keep from the twelfth century.
This castle was undoubtedly again dismantled by Cardinal Richelieu under the reign of Louis XIII. Today two wings remain. Inside the castle is a monumental fireplace and painted decorations from the XVth century.
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.
