The small island Utö in the archipelago of Stockholm is famous for its iron ore. The ore was mined as early as the 12th century, and so this is the oldest iron mine of Sweden. Today there are traces of the mining era in the deep waterfilled mine holes, the big piles of mine tailings and Lurgatan with its old houses, 18th century, where the miners lived. In the small mining museum, open every day in summer, you can learn about the history of the mines and look at interesting collections from that time.
References:The museum is only open from 13.oo to 16.00 h !
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.
