Château de Laréole was built in 1579 by Pierre de Cheverry, a son of a great pastel merchant. The construction of the castle lasted three years and the Cheverry family kept the castle until 1707. After the Great Revolution, the castle changes hands several times before it was abandoned in1922. In 1984 the General Council of Haute-Garonne bought the property and restored it. Today the site is open to the public and guided tours are available.
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.
