The Stork Tower with fragments of the city walls has survived from the medieval fortification of Dobre Miasto. It was built in the 14th century. The tower owes its name to storks which have nested on its top. At present the tower is the residence of one of the sections of the Cultural Society. In the summer season tourists can visit a miniature museum created by the members of the society.
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.
