Lillö Castle was built in in the 14th century among the natural defences offered by the inaccessible marshlands and the River Helge å. The first known owner was Åke Axelsson (Tott) in 1343. The castle belonged to Tott, Trolle and Huitfeldt families until it was destroyed in 1658–59. Today, displays inside the castle based on the finds made during various archaeological digs reflect life here in days gone by. Display panels in the courtyard provide information on the castle and its surroundings. A key is available from the Naturum Vattenriket visitor centre to gain admission to the castle.
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.
