The Château de Saint-Izaire is a 14th-century episcopal castle. It is maintained by an association known as Vie et Château (Life and Castle), who have created a mini museum on the premises to record the history of the castle and the inhabitants of the village of Saint-Izaire.
The castle is a massive quadrangular red stone building that shelters the town hall of the village of Saint-Izaire. The structure is supported by a keep-tower in the southern wing (partially demolished since the 19th century). This keep contains mural frescoes dating from the 14th century, and the ceiling in the room of the bishops in the Baroque style of the 17th century.
The castle was built by Guillaume Rotlindes, ancestor of the current Rollinde de Beaumont. It was intended as a gift to the Abbey of Vabres, close to the commune of Saint-Affrique: the deed attesting the gift is preserved to the present day. The castle was often used as a summer residence by the abbey. When the cathedral and palace of Vabres were razed in the wars of religion, the castle was used by refugees from the abbey.
The Château de Saint-Izaire is one of a group of 23 castles in Aveyron who have joined together to provide a tourist itinerary as the Route des Seigneurs du Rouergue.
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.
