The construction of the Przezmark castle started at the beginning of the 1300s continued until c. 1350. In the next centuries the stronghold was repeatedly converted because it was adjusted to new functions: the seat of a commune head, a prosecuting attorney and a convent. Since the beginning of the 16th century the castle belonged to the bishops of Pomesania as to later come into hands of the families of von Egmon and von Verdte. After the period of the private owners, came the period, in which the stronghold performed the function of the seat of the offices to finally decline and to be disassembled in the 18th century The first of the old names of the castle suggests that before the Teutonic times there existed the Prussian merchant settlement. The tower that has survived till our time emerged around 1329 and is called the Prisoner-Of-War Tower.
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.
