On 17 June 1947, Prince Eugen, the fourth and youngest son of King Oscar II and Queen Sofia, wrote his will. “He wanted the buildings, art and green areas to not just be preserved, but made accessible in a dynamic way,” says Karin Sidén, museum director at Prins Eugen’s Waldemarsudde. “He described his vision in such an open and generous way. He didn’t want for this to be a mausoleum over his dead body but a vivid, lively environment that changes with the times and mirrors interesting artistry.”
