Prince Eugen was one of his generation’s foremost landscape painters and many of his best-known works, including Molnet (the Cloud) and Det gamla slottet (The Old Castle), are part of the collections at Waldemarsudde. He was also an art collector and his collection of Swedish turn-of-the-19th-century art is one of the foremost in the country. In the Mansion the Prince’s Private Apartments remain mostly unchanged, while the two upper floors – with the Prince’s Studio at the top – are used for temporary exhibitions or for exhibiting works by the Prince or from his collections. The Gallery Building is mainly used for temporary exhibitions.
