Dobbertin Abbey is a former Benedictine monastery of monks, afterwards housed a community of nuns, and later still a women's collegiate foundation. The abbey was founded during the Christianisation of Germany in about 1220 by Prince Heinrich Borwin II of Mecklenburg and was the first field monastery in Mecklenburg. The founder gave it to the Benedictines for a community of monks. 15 years later it was turned into a Benedictine nunnery.
In 1549 the Landtag at Sagsdorf Bridge near Sternberg resolved to introduce the Lutheran Reformation into Mecklenburg. Despite violent resistance the abbey was secularised and in 1572 converted into a Lutheran collegiate foundation for noblewomen.
In the middle of the 19th century the church was restored by Georg Adolf Demmler to plans by Karl Friedrich Schinkel. The work was completed in 1857.
In 1918 the abbey premises became the property of the state and were converted into a youth hostel. After World War II Soviet troops were stationed here, and destroyed much of historical interest.
From 1947 to 1991 the buildings were used as an old people's residential and care home. Then they were transferred to the responsibility of the charitable organisation of the German Evangelical Church, who set up a care home for the severely physically handicapped.
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.
