Ganagobie Abbey is a Benedictine monastery in Ganagobie in the department of Alpes-de-Haute-Provence, France. The first monastic foundation on this remote and mountainous site appears to date from the 9th or 10th century. Among the first documentary records is a bull of Pope Stephen VIII in 939 confirming the possessions of Cluny Abbey, among them the monastery at Ganagobie. It was suppressed in 1789 under the Ancien Régime and sold off in 1791 during the course of the French Revolution, after which large parts of the buildings were demolished.
In 1865 the Benedictines of Solesmes under Dom Prosper Guéranger founded the Priory of St. Madeleine in Marseilles, or Marseilles Priory. In 1891 the Comte de Malijay, by that time the owner of the priory site at Ganagobie, made a gift of to the Marseilles Priory. In the course of repair and restoration work on the new property, important medieval mosaics were discovered in 1898.
In 1901 however the community at Marseilles were forced by the Association Laws to leave France. They took refuge in Italy and did not return until 1922, when they took up residence at Hautecombe Abbey, of which Ganagobie was from then on a priory, of one or two monks only.
In 1987, after decades of restoration work, the whole community of Hautecombe decided to move to Ganagobie, which they did in 1992.
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.
