Attel Abbey was a monastery, originally of the Benedictines, later of the Brothers Hospitallers. The monastery, dedicated to Saint Mary the Virgin and Saint Michael was founded as a Benedictine abbey by Count Arnold of Diessen-Andechs in around 1037. It was dissolved in 1803 in the secularisation of Bavaria. The abbey buildings were partly demolished, partly acquired by private owners.
In 1874 the Bavarian government set up a home for disabled men in the remaining premises, the running of which they entrusted to the Order of the Brothers Hospitallers. Apart from the years of World War II, when under the National Socialist government the Brothers were obliged to close the home and leave, they remained here until 1970, when declining numbers forced them to give up Attel. The running of the home was taken over by the Charity Union of München-Freising until 1994, when it became independently managed.
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.
