Škrljevo Castle was first mentioned in written documents dating to 1044. The current building dates to the 15th and 17th centuries with some 19th-century rebuilding. Nationalized building is nowadays empty. Bare witness of its former glory is walled, though totally neglected garden and remnants of a park with old yew and lime trees and in its front.
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.
