Falkenberg Castle was founded probably between 895-898 AD, but not mentioned before 1154. In 1294 Aldsassen monastery bought it. In 1428 the monks successfully defend the castle against the Hussite invasion. During the Thirty Years' War in 1648 Hans Christoff von Königsmarck (Swedish-German soldier) conquered the castle and left it in ruins.
After been decayed for centuries, Friedrich-Werner Graf von der Schulenburg, a German diplomat and ambassador in Moscow, bought the castle as his retirement real estate. Following images from old paintings, he rebuilt the castle from 1936 – 1939. Schulenburg was part of the Operation Valkyrie, the failed assassination of Adolf Hitler. He was executed shortly after in 1944. The Gestapo confiscated the castle in World War II and arrested prisoners from the Flossenbuerg concentration camp. After the war, the Schulenburg family assumed ownership of the property.
Since its grand opening in 2015, visitors are invited to explore the castle’s museum and spend a night in the castle hotel. The castle also features a unique restaurant and a large knight’s hall for events.
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.
