Around the third quarter of the 12th century Freiherr von Weissenburg donated land along the Simmen river to the Augustinian order for a monastery. The monastery was first mentioned in 1228 along with the surrounding village. In 1368 the Freiherr von Brandis inherited the Weissenburg lands including patronage of the monastery. It continued to expand during the 13th and 14th centuries as nobles donated lands and the monastery bought estates.
The monastery church of St. Mary became the burial church of the Freiherrs. In 1439 the city of Bern acquired the Weissenburg lands including the monastery and the village. In 1486 they forced the monastery to accept the authority of the college of canons of the Cathedral of Bern. In 1528, Bern adopted the new faith of the Protestant Reformation and secularized the monastery. The monastery church became the parish church of newly created parish.

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.
