The Priory of St. Michael, dedicated to Saint Michael, was founded in 1141 by Gebhard von Roning, as a monastery of Canons Regular, which it remained until 1598. It was re-founded in 1616 by monks from Andechs Abbey as a Benedictine community, which was dissolved during the secularization of monasteries in Bavaria in 1803.
The monastery was bought in 1974 by the Canons Regular of the newly refounded Congregation of Windesheim, and is the motherhouse of this revived congregation.
The buildings had been bought by a farmer during the 19th century, and they were partially destroyed.
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.
