The major restoration took place after 1875 by the Count Brandis and later by Countess Anna Asseburg-Wolff-Metternich and his husband. Their descendants are still in possession.
The 21m high tower was erected for the defensive purposes and the castle was built around it. during The late Gothic chapel dates from 1455. The imposing structure, surrounded by a 5-hectare park, now houses a hotel and is used for conferences.
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.
