Stargard Castle is the northernmost preserved hilltop castle in Germany and the oldest secular building in Mecklenburg-Vorpommern at the same time with the deepest dungeon tower in northern Germany. It was built in the 12th and 13th centuries.
During the Thirty Years' War, the castle served as headquarters for Johann t'Serclaes, Count of Tilly, general of the Imperial forces, later becoming a seat of ducal administration. The town suffered during the general decline of the region in the aftermath of the Thirty Years' War.
The castle is now a major tourist attraction in the area, with spectacular views from the tower and special events such as an annual knights' tournament.
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.
