Château de Buzet-sur-Baïse was built originally in the 10th century and rebuilt in the 12th century. There was actually two castles on the site and the church. Castles were burned down in 1293-1294 by the English army. Today the oldest parts date from the late 13th century. The chateau was restored in the 17th century. With its outbuildings and its park, it was acquired in 2018 by the Buzet winegrowers cooperative cellar and must occasionally host cultural or festive events. It is not open to visitors.
Until then, the old 13th century castle chapel, altered in the 16th century, served as a parish church. Decommissioned after part of the vault collapsed in 1849, its remains remain.
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.
