The history of Laval Dieu begins in this place formerly called “la Bouche de Semoy” when the Archbishop of Reims, Hincmar, had a chapel built in 867, that was dedicated to Saint Rémy and entrusted it to the secular canons from the Braux Collegiate Church with a view to evangelising the region. Twelve canons from Prémontré arrived in the month of June 1128, at the beginning of the Semoy Valley which then became for evermore the “Vallis Dei”, the Vallée de Dieu, Laval-Dieu. Right from the moment it was founded Laval Dieu Abbey received as alms or in exchange for prayers, the inherited lands in Monthermé and further beyond in the neighbouring areas situated in the Empire, such as Auton wood in the Roc la Tour direction, owned by the Orchimont family. That is how Monthermé became an entity, a village, a seigneury whose lord of the manor was the Abbot of Laval Dieu. The inside of the church’s walls is entirely covered with oak panelling up to a height of 3.50 m that was installed in the early years of the 18th 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.
