Sarrance Monastery belonged to the Betharram Fathers who had replaced the Premonstratensians who left after the French Revolution. The Premonstratensian order founded their monastery in this place in 1345, the site of a Marian pilgrimage dating from the 12th century. They maintained religious services in this place, served the parish and welcomed pilgrims and travellers on the Roman road to Santiago de Compostela.
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.
