Schönau Abbey was a Cistercian monastery founded in 1142 from Eberbach Abbey. The present settlement of Schönau grew up round the monastery. By the end of the 12th century Schönau was already in use as a burial place of the Staufen family: in 1195 Conrad of Hohenstaufen, Count Palatine of the Rhine, was buried here, as were his son of the same name, probably in 1186, and both his wives. Adolf, Count Palatine of the Rhine (d. 1327), Rupert II, Elector Palatine (d. 1398) and other members of the family were also buried here. Conrad II, Bishop of Hildesheim, died here and was presumably also buried here. In the 14th century Schönau was also the burial place of the Counts of Erbach.
During the Reformation the abbey was dissolved, in 1558. The empty buildings were occupied in 1562 by Huguenot refugees from Wallonia, to whom Schönau gave rights of residence.
Physical remains of the abbey include the abbey church of c. 1230, and also the abbey gateway (c. 1200), the former refectory, and the 'Walloon forge' (the former abbey forge, renovated by the Huguenot refugees from Wallonia after 1558).
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.
