Denmark's Prince Henrik, the husband of Queen Margrethe, has been transferred from a Copenhagen hospital to Fredensborg Castle north of the city, where he wants to spend "his final time", the Royal House says.
His condition remained serious, a statement on Tuesday said. Henrik is the father-in-law of Crown Princess Mary.
The 83-year-old French-born prince was diagnosed with a benign tumour two weeks ago. He had been hospitalised following an illness that began during a private trip to Egypt.
His oldest son, Crown Prince Frederik, a member of the International Olympic Committee, returned home from the Winter Olympics in South Korea last week to be with Henrik after his condition "seriously worsened".
