The first mention of Wernberg Castle dates to 1280 when Konrad of Paulsdorfer bought the building. By the following year, Burg Wernberg was the family seat of the noble Notthafft family under the Landgrave of Leuchtenberg. By 1647 Wernberg came into the possession of the Electorate of Bavaria. During the Austrian War of Succession, the castle was used as a military camp.
In the 19th century, the castle was used for not-so-glamorous purposes. In 1804, it served as a prison, in 1861 as a rescue institution for fallen women and neglected girls. By 1873, serious consideration was given into just demolishing the building, but that idea never went anywhere.
The town of Wernberg acquired the castle in 1992 and rented it to the Conrad family for a term of 99 years. By 1998, the castle opened its doors as a hotel, becoming one of the top 100 best hotels in Germany in the same year.
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.
