Axevalla Hus is a ruined medieval castle. It was first mentioned in 1278. In 1323 the castle was owned by Danish and besieged by Swedish army. It was reconstructed in the 14th century under the order of Albrecht of Mecklenburg. In 1436 the castle was again besieged and given to Swedish.
In 1469 Axevalla Hus was destroyed in the war between kings Karl Knutsson (Bonde) och Kristian I and it was never rebuilt. Today there are only some remains left.
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.
