The Castle of Mey was owned by the Queen Mother and the Queen from 1952 until 1996, when it was gifted to the public as a historic building.
It was a particular favourite of the Queen Mother, who used the Caithness property to entertain friends and escape the hustle and bustle of London.
The Duke enjoyed a tour of the pristine new accommodation, which has been in the pipeline at the castle for several years.
