Originally Loosdorf Castle was built as a fortress in medieval times. It was first officially mentioned in 1320, however, based on certain archived documents it was most likely built already in the 10th century. In the course of the Thirty Years' War and due to a massive fire in 1645 parts of the castle were destroyed. Afterwards the castle changed its owners frequently. In 1740 the Liechtenstein Family became the owner of the castle. Between 1760 and 1810 Emmanuel Duke of Liechtenstein executed a lot of construction and decoration works in and around the castle. Based on its long-standing history the castle shows medieval, classicistic and renaissance elements.
1834 Count Friedrich Piatti acquired Loosdorf castle and moved the family residence and their porcelain collection from Dresden to Loosdorf. They were the first Piatti's who partly lived there. Since then the castle is in the possession of the Piatti Family.
References: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.
