The ruins of Landshut Castle loom over Bernkastel. Archbishop Heinrich von Vinstingen and his successor, Boemund, are said to be responsible for the construction of the castle in 1277. They were the ones who gave the castle its name, 'Landshut', which it is still known by today. The castle, along with all of its treasures, was destroyed by a fire in 1692. However, it is still possible to climb the castle tower. In the inner courtyard of the castle there is a restaurant and a café. The ruins are surrounded by various paths, offering visitors a range of leisurely hiking routes. The Hunsrück mountain range with its deep forests and gorges is also easy to reach from here and well worth exploring.
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.
