Malla manor traces its history back to 1443, when it is first recorder in written sources. During that time, there was a small castle at the site. Around 1620, the estate became the property of Swedish field marshal Gustav Horn. In 1651-1654, he commissioned architect Zakarias Hoffmann to erect a new manor house on the site. The house burnt down during the Great Northern War, and the current building received its appearance in the 1880's. The estate is now privately owned.
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.
