Cecilienhof Palace was built from 1914 to 1917. Emperor Wilhelm II ordered the establishment of a fund for constructing this new palace at Potsdam for his oldest son, Crown Prince Wilhelm (William) and his wife, Duchess Cecilie of Mecklenburg-Schwerin on 19 December 1912. Cecilienhof was the last palace built by the House of Hohenzollern that ruled the Kingdom of Prussia and the German Empire until the end of World War I. It is famous for having been the location of the Potsdam Conference in 1945, in which the leaders of the Soviet Union, the United Kingdom and the United States took important decisions affecting the shape of post World War II Europe and Asia. Cecilienhof has been part of the Palaces and Parks of Potsdam and Berlin UNESCO World Heritage Site since 1990.
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.
