Notre-Dame-de-la-Fin-des-Terres Basilica, a UNESCO world heritage site since 1998 as part of the Routes of Santiago de Compostela. Tradition goes back to the legend of St. Veronica, the origin of this church. In the first century of our era, after the death of the Virgin, Saint Veronica, Saint Amadour and Saint Martial from Palestine, landed in Soulac. Veronique then raised a modest oratory to the memory of the Virgin, after evangelizing the Medoc and the Bazadais. She died in Soulac and was buried in the year 70.
It was probably in the 11th century, when the pilgrims of Saint-Jacques from the English lands landed in Soulac, that was built this Benedictine abbey, classified Historic Monument. The construction of the Romanesque church did not end before the beginning of the 12th century. In the 18th century, dune erosion caused the quasi-total silting up of the church, which was not cleared until the middle of the 19th century.
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.
