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 theĀ 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:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
