There are over 100 rock carvings depicting rich and wide variation of themes in Torsbo, including the longest boat carving in Sweden (4,5m). There are also figures of a tree, and several warriors carrying swords. Many of the warriors are depicted as having enlarged calves, a feature that is typical for this area. It cannot be rulled out that several of the carvings were made by the same person. The carvings as a whole have, however, been made over a period of some 1000 years. Many of the ships date from the early Bronze age, around 1800-1500 B.C. while most of the warriors are thought to date from the end of the Bronze Age, around 700-500 B.C. There are often features of both motifs on the same rock face, indicating that the place was used and was a holy place for many generations.
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.
