Släbro is without question one of Sweden’s greatest and most remarkable rock carvings site. Situated near the River of Nyköping the carvings were discovered 1984 and can be dated back to the Bronze Age. They are unique because they are carved in a most unusual way. There are etchings on some ten different surfaces with a total of some 700 figures, mainly frame and circle figures. Many are unique in design, in particular the large stylised human figures in a position of adoration. The characteristics commonly found throughout carvings in the South of Sweden are missing. What is more, the Släbro carvings seem to bear no similarity to any other ancient carvings that have been discovered throughout Europe. The carvings date from 1800 – 400 BC and thus far the meaning behind them remains something of a mystery as it has proven to be extremely difficult to interpret the motif as it appears in literally hundreds of different ways.
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.
