St Petersberg Castle is located on a hill to the west of the village of Silz. There is a pond to the south of the castle and the towering, five-story square keep is crowned with battlements. Beyond the castle is the so-called 'Schnitzer Tower', also known as the 'Faul Tower', which was originally the seat of the burgraves.The castle was originally an estate or imperial fief owned by the House of Welf and was the centre of the earldom in the Oberinn Valley. St Petersberg was first mentioned in documents dating back to 1090/97 and was referred to as 'Neuhaus' (new house) in the 12th and 13th centuries. Today, the castle is home to an all-male monastery and a convent is located at the foot of the Petersberg. The castle is privately owned and can only be viewed from the outside.
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.
