Wechterswinkel Abbey, dedicated to the Holy Trinity and Saint Margaret, was founded in 1134 or 1135 by Embricho of House of Leiningen, bishop of Würzburg, and King Conrad III of Germany.
It was so severely damaged in the wars of the 16th century that it was unable to continue, and was dissolved in 1592 by Julius Echter von Mespelbrunn, the then bishop of Würzburg. The assets realised were invested to endow parish benefices and schools.
The church, a Romanesque basilica heavily altered in the early 19th century, has survived as the village parish church, now dedicated to Saints Cosmas and Damian.
Some of the monastic buildings also survive, put to secular uses, but have been comprehensively altered and retain no medieval character.
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.
