In 1437, members of the Order of the Knights of the Cross founded the late Gothic Bentlage Monastery. It was extended again and again. In 1803 it was secularised and became the residence of the Rheine-Wolbeck principality. Only three years later it was handed over to the noble family Looz-Corswarem. They converted the former monastery into a castle.
Since 1978 the property has been owned by the city of Rheine, which developed it into a cultural meeting place and monastery museum from 1989 to 2000. The highlight of the exhibition there are two reliquaries, which are unique in their state of preservation in the German-speaking world. Sophisticated temporary exhibitions regularly attract numerous visitors.
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.
