Princess Anne is recovering from a bad chest infection and has cancelled all her public duties for the coming week, Buckingham Palace says.

Queen Elizabeth‘s only daughter – who’s known for her flinty and athletic character (and titled the Princess Royal) – was taken to the hospital on Wednesday after falling ill during the family’s stay on the Balmoral estate in the Scottish Highlands.

A palace spokesman tells PEOPLE, “The Princess Royal is recovering from a bad chest infection. On doctors’ orders she has cancelled her engagements for the coming week.

“She is resting privately at home.”

It was not an emergency and Anne, 66, did not need an ambulance for the journey on Wednesday to Aberdeen Royal Infirmary 50 miles away. After some tests she headed back to Balmoral.

Anne, who is grandmother of three, including to little Mia Tindall, is known to be one of the hardest working members of the royal family (she undertook 544 public engagements last year, topping those of her brother Prince Charles).

And she was sitting beside Charles as he and other members of the family joined Queen Elizabeth and Prince Philip to watch the traditional highland games at Braemar.

Wiliam and Kate and their children are expected to head there to the Scottish estate too.

Anne was the only one of Elizabeth’s four children to have her own portrait with the Queen when she marked her 90th birthday in April.
