Kirn's foremost landmark, standing above the town, is the Kyrburg, a former hill castle, now a ruin. It lies between the Nahe and Hahnenbach valleys high above Kirn. In 1128, the Kyrburg had its first documentary mention in a document from Count Emich de Kirberc. The castle was one of the seats held by the Waldgraves (whose successors were the Emichones). By the late 13th century, the Waldgraves had split into several lines, one of which named itself after the Kyrburg. In 1409, the Rhinegraves took over the holding through marriage.
In the Thirty Years' War, after being occupied by the Spaniards, the Swedes and Imperial troops, it fell into French hands in 1681. Eight years later, a replacement of the defensive complexes was undertaken. In 1734, the stronghold was once again under French occupation, and in the course of the War of the Polish Succession, it was blown up.
The ruin thereafter served the townsfolk as a stone quarry. In 1764, Prince Johann Dominik had the garrison house built, which nowadays houses the Restaurant Kyrburg, and in the cellar, the well known whisky museum. In 1908, the castle complex past into the ownership of the Princes of Salm-Salm; since 1988, it has been owned by the town of Kirn.
As an outdoor stage, the ruin offers a dramatic backdrop for cultural events. In the past, several operas have been staged there (mainly ones by Giuseppe Verdi). It is also a venue for plays, concerts and celebrations.
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.
