Mörby was first mentioned 1387 as built by the knight Henrik Damerow. Since 1452 it was owned by Oxenstierna family over 250 years. 1550 the castle was rebuilt after a fire. In 1733 it was left as a decay and the roof was ripped off and moved to Ekeby Castle. Finally Mörby was destroyed by fire in 1740. Today still impressive ruins remain including a tower body.
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.
