Castres Cathedral (Cathédrale Saint-Benoît de Castres), now the Roman Catholic church of Saint Benoît, was formerly the seat of the bishop of Castres, but the diocese was not restored after the French Revolution and was added by the Concordat of 1801 to the Archdiocese of Albi.
The first cathedral was built in the 14th century after the creation of the diocese of Castres in 1317, along with a number of other dioceses created in the region after the suppression of the Albigensians. It was destroyed during the French Wars of Religion.
The present building which replaced it was constructed in the 16th and 17th centuries.
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.
