The Cistercian convent moved to Nimbschen before 1291 from Grimma. The Cistercian nuns faced financial difficulties in the late Middle Ages, and reforms were attempted by the Wettin rulers and Pforta abbots. Despite extensive renovations in the early 16th century, the community faced challenges. The influence of the Reformation became evident, leading to the escape of nine nuns, including Katharina von Bora, Luther's future wife, in 1523. The last Abbess, Margaretha, died in 1536, leading to the dissolution of the convent in 1536. The estate continued under a steward until Kurfürst Johann Friedrich von Sachsen leased it in 1542.
After secularization, from 1550 to 1948, Nimbschen belonged to the Fürstenschule in Grimma, providing financial support for gifted students. The secularized estate was managed by the Grimma school office, overseeing the school's economic well-being.
Over time, the convent buildings deteriorated, and in 1810, they were repurposed for construction material. In 1901, a new estate was built using the remaining materials.
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.
