Camilla’s Reading Room was created by the Duchess in 2020 to promote literature and reading during coronavirus lockdowns.

This recently involved the “planting” of books in local phone booth libraries in recent weeks.

On this occasion, Camilla presented herself to donate to the library.

Originally purchased by her husband the Prince of Wales, it was moved to its current location on the B976 three years ago.

English royal correspondent Rebecca explained some of the background to the phone booth on Twitter.

She said: ‘Across the UK, communities are turning their distinctive red phone booths into’ micro-libraries’.

“But this one on Royal Deeside is something special.

“The original kiosk designed by Sir Giles Gilbert Scott was purchased by the Prince of Wales three years ago and placed on the B976!”
