Glandèves Cathedral, now the Chapelle de l'Hôpital, is a Roman Catholic church located in the former town of Glandèves, Alpes-de-Haute-Provence. It was abandoned in the Middle Ages for the more secure site of the present Entrevaux. Only the chevet remains, which has been converted into a chapel.
The ancient town of Glandèves occupied an exposed site that was frequently attacked and pillaged. In the 11th century the inhabitants moved to a more secure and defensible settlement at Entrevaux, although the Bishop of Glandèves remained seated at the cathedral on the old site.
Between 1609 and 1624 a new cathedral was built in Entrevaux, which became the seat of the diocese at its completion.
The old cathedral and the adjoining episcopal palace buildings were sold during the Revolution and subsequently used as a boarding house and a hospital, whence the alternative name for the present chapel as the Chapelle de l'Hôpital. The remaining structure dates from the 12th century, with some work from the later 16th century. The conversion to the chapel is modern.
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.
