The village of Karpniki, situated at the foot of the Sokole Mountains, is mentioned for the first time in the 14th century. The castle, whose history dates back to the 15th century, lies amidst the picturesque scenery of the mountainous landform and the surrounding hills and is connected with distinguished Silesian families.
The castle was redecorated in a Neogothic style in 1844 according to the plans of Friedrich August Stüler for Prince Wilhelm of Prussia who had purchased the estate in 1822. His brother, King Frederick William III, visited him several times and in 1831 bought nearby Erdmannsdorf Estate for himself, and in 1839 Wojanów (Schildau) Castle for his daughter Princess Louise of the Netherlands. Jelenia Góra Valley became a royal hideaway. The prince's daughter, Marie of Prussia, had her confirmation in the Lutheran Fischbach church in the spring of 1842, with King Frederick William IV and his wife Elisabeth Ludovika of Bavaria being present, as well as their nephew, the Bavarian Crown Prince and later King Maximilian II, Marie's fiancé, whom she married later that year. The following year their first son was born, who became the famous king Ludwig II.
Today Karpniki castle is a luxury hotel.
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.
