The duration of the couple's much-needed respite remains uncertain; however, given the tumultuous beginning to the year for the family, Charles and Camilla are expected to cherish this opportunity for some quality time together.

King Charles's affection for the luxurious Birkhall estate, nestled along the picturesque banks of the River Muick, is widely known, often seeking solace in its serene surroundings whenever his schedule permits.

"It is such a special place, particularly because it was made by my grandmother. It is a childhood garden, and all I've done, really, is enhance it a bit," the king said to Country Life regarding the estate's gardens.

Additionally, the estate holds sentimental significance for both King Charles, 75, and Queen Camilla, serving as the idyllic setting for their honeymoon following their union in 2005. Establishing a cherished tradition, the couple has since commemorated each anniversary at the estate.

Having exchanged vows on April 9, 2005, the royal pair celebrated their 19th wedding anniversary on Tuesday.
