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.
Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
