Prins Eugens Waldemarsudde is a museum located on Djurgården in central Stockholm. It was the former home of the Swedish Prince Eugen, who discovered the place in 1892, when he rented a house there for a few days. Seven years later he bought the premises and had a new house designed by the architect Ferdinand Boberg, who also designed Rosenbad (the Prime Minister's Office and the Government Chancellery), and erected 1903–1904.
Prince Eugen had been educated as a painter in Paris and after his death the house was converted to a museum of his own and others paintings. The prince died in 1947 and is buried by the beach close to the house.
The complex consists of a castle-like main building completed in 1905, and the Gallery Building, added in 1913. The estate also includes the original manor-house building, known as the Old House and an old linseed mill, both dating back to the 1780s. The estate is set in parkland which features centuries-old oak trees and reflects the prince's interest for gardening and flower arrangement. The Art Nouveau interior, including the tiled stoves, by Boberg are designed in a Gustavian style and makes good use of both the panoramic view of the inlet to Stockholm and the light resulting from the elevated location of the building.
References:Ehrenbreitstein Fortress was built as the backbone of the regional fortification system, Festung Koblenz, by Prussia between 1817 and 1832 and guarded the middle Rhine region, an area that had been invaded by French troops repeatedly before. The fortress was never attacked.
Early fortifications at the site can be dated back to about 1000 BC. At about AD 1000 Ehrenbert erected a castle. The Archbishops of Trier expanded it with a supporting castle Burg Helferstein and guarded the Holy Tunic in it from 1657 to 1794. Successive Archbishops used the castle's strategic importance to barter between contending powers; thus in 1672 at the outset of war between France and Germany the Archbishop refused requests both from the envoys of Louis XIV and from Brandenburg's Ambassador, Christoph Caspar von Blumenthal, to permit the passage of troops across the Rhine.
