he Notre-Dame de la Grainetière abbey is located in the commune of Les Herbiers. It was founded in 1130 by Benedictine monks from the Abbey of Fontdouce en Saintonge. However, construction began in earnest at the end of the 12th century to become an ensemble considered to be exemplary of Romanesque art in Vendée.
Several times burned down or looted during the Hundred Years War, then during the Wars of Religion, the abbey was partly restored at the beginning of the 17th century. However, in 1760, only one monk remained. During the Revolution convent buildings were sold to a farmer and the abbey church was gradually demolished.
It was not until 1963 that the site was bought and a long restoration campaign began and in 1979, a priory was established within the walls (religious from the Notre-Dame d'Espérance congregation still occupy the monastery).
The remains of the primitive abbey are highlighted, in particular the west gallery of the Romanesque cloister, with its small semicircular arches and double columns, the chapter room transformed into a chapel, three apses of the transept of the church abbey and two defensive towers to the south, one of which, known as the Abbot's Tower, was restored in 2001.
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.
