Morimond Abbey was the fourth of the four great daughter abbeys of Cîteaux Abbey, of primary importance in the spread of the Cistercian Order. Morimond was founded in 1115 by Count Odelric of Aigremont and his wife Adeline of Choiseul and settled from Citeaux. The first abbot was Arnold the German. Thanks to his energy and influence, Morimond grew very rapidly, and established numerous colonies in France, Germany, Poland, Bohemia, Spain, and Cyprus.
Over the next two centuries Morimond continued to be active in the foundation of new Cistercian houses, so much so that towards the end of the 18th century, Morimond counted amongst its filiations nearly seven hundred monasteries and nunneries.
The cruciform abbey church with three aisles and closed choir, the sides of which are occupied by chapels linked by a gangway, was built to be restrained and severe, according to the Cistercian building prescriptions, without towers or artistic adornment. In 1572, during the Wars of Religion, and again in 1636 in the Thirty Years' War, Morimond was destroyed; it was abandoned in 1791 in the French Revolution. Only the church survived, but fell into ruin during the 19th century.
Today, of the medieval structures, only a fragment of the north aisle is still standing, although there remain from the 18th century the gateway, the library and some pavilions and arcades.
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.
