Přimda castle dates from the early 12th century and represents early Romanesque architecture. The castle is probably of German origin, not similar to Czech buildings from this period, but strikingly reminiscent of period Bavarian buildings. The remains of a Romanesque residential tower and the castle bastion invite you not only to see the ruins, but also to look into the beautiful surrounding landscape of the Bohemian Forest.
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.
