The original Hainewalde water castle, built under rule of the family von Nositz, was located north of the terraces of the new castle. The only remain of the old water castle, which was demolished in 1780, is the gate lodge with his west-side Renaissance-portal. Schloss (New Castle) was constructed in 1750–1753, along with its Baroque gardens, under the rule of the Kanitz-Kyaw family. It was renovated in 1883, the Baroque elements on the outside façade removed and replaced by 'Italian'-style sgraffito.
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.
