Wurmsbach Abbey is a monastery of Cistercian nuns located in Bollingen, a locality of Rapperswil-Jona. Count Rudolf of Rapperswil gave his castle of Wurmsbach together with a considerable area of land in 1259 for the foundation of a religious house and the abbey was established. It was initially a dependency of the Cistercian monks of Abbey of St. Urban in Wettingen. The abbey church was dedicated in 1281. Bollinger Sandstein was used for the construction of the abbey by dedicated quarries.
During the first Battle of Villmergen in 1656 and again during the occupation of the region by the French Revolutionary Army in 1799, the nuns were obliged to flee. On both occasions the abbey was completely pillaged, with the consequence that there are few treasures left.
The abbey is renowned for its location at the lake side. It overlooks uper Lake Zürich and the church is listed as a building of historical significance. The nuns run a secondary boarding school for girls. The gardens are known for the herbal remedies grown.
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.
