Trolle-Ljungby Castle, enclosed by a moat, is one of most magnificent Renaissance buildings in Sweden. In the Middle Ages it was a fortified manor house, owned by Bille family. The current castle was erected in 1629 to the grounds of the previous castle, which had been burnt down in 1525. The west wing was added in 1633 and the east wing in 1787. The stone bridge in the northern side dates from 1806. The current owner of the castle is count Hans-Gabriel Trolle-Wachtmeister with her wife countess Alice Trolle-Wachtmeister, the Swedish Mistress of the Robes.
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.
