Reichenbach Abbey, dedicated to the Assumption of the Blessed Virgin,was founded in 1118 by Markgraf Diepold III of Vohburg and his mother Luitgard. During the Reformation it was looted, and secularised from 1553 to 1669, when it was re-established. It was dissolved again in 1803 during the secularisation of Bavaria. The abbey's property was confiscated by the state and eventually auctioned off in 1820.
After a couple of unsuccessful attempts to restore it as a religious house, the site was acquired in 1890 by the Brothers Hospitallers, who established a nursing home for the mentally and physically handicapped. Today there is in addition a special school teaching therapeutic care.
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.
