Rühn Abbey is a former Cistercian monastery founded by Brunward, bishop of Schwerin in 1232. Already on May 29, 1292 the monastery was burned down completely. After reconstruction 30-40 nuns lived, prayed and worked there.
After the Reformation Duke Ulrich gave the monastery to his wife Elisabeth. She founded in Rühn the first girls' school in Mecklenburg. Numerous renovations and extensions were made then.
In the Thirty Years War the monastery was destroyed. During the age of the Duchess Sophie Agnes von Mecklenburg (1625-1694), it was rebuilt with a park with linden alley in the former monastery garden. Until 2008 the site changed hands several times and functioned for example as an orphan house. Since 2008 it has been owned by the Klosterverein Rühn e.V foundation.
The abbey church was completed in 1270.
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.
