St. Vitus' Abbey on the Rott was a Benedictine monastery founded in 1121 by the nobleman Dietmar of Lungau, and dissolved during the secularisation of Bavaria in 1802.
The premises were given at first to the Damenstift of St. Anna in Munich, but in 1829 came into the possession of the Saxon Baron Maximilian von Speck-Sternburg and then in 1858 were sold to Count Maximilian von Montgelas.
Formerly in the diocese of Salzburg, the abbey was a member of the Benedictine Salzburg Congregation from 1641 until its dissolution.
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.
