A memorial to the late Queen Mother has been unveiled outside a church in the Highlands by the Duke and Duchess of Rothesay.
Charles and Camilla have been taking a summer break at the Castle of Mey in Caithness, the former holiday home of the Queen Mother.
The slate memorial is at the church in the small community of Canisbay, where the Queen Mother used to worship.
On Saturday, the duke and duchess attended the local Mey Games.
The oval plaque includes a touching inscription written by Charles, as well as a likeness of his grandmother's smiling face.
The prince commissioned sculptor Adam Williamson to carve the personal tribute to her memory.
After attending a mid-day service at Canisbay with about 150 parishioners, the creation was officially unveiled to applause from spectators.
Charles, wearing a Rothesay tartan kilt, was next to his wife as they chatted to Mr Williamson.
Camilla was dressed in her favourite Roy Allen-designed claret coat, edged with the Rothesay colours, which she wore during her honeymoon last year at Balmoral.
London-based Mr Williamson, 24, spent 18 months etching the plaque from a block of Lake District Burlington slate.
The sculptor, who has completed other carvings for Charles, said: "He was very involved in the whole process, much more so than for my other projects.
"He had a very firm idea of what he wanted and you could tell it meant a great deal."
The Queen Mother was a regular visitor to the Castle of Mey
He added: "The prince said the plaque was marvellous."
The Castle of Mey, near John O' Groats, was one of the Queen Mother's favourite retreats.
She bought it after her husband's death in 1952 and restored it to its former glory.
She became a regular visitor to the area over several decades and retained ownership of the property until 1996.
It was then handed over to a charitable trust, along with its 2,000 acres and a herd of prize-winning Aberdeen Angus cattle, and has opened its doors for public tours.
The Queen Mother died in March 2002, at the age of 101.
Last month, the Royal Family officially opened a garden in her memory at Edinburgh's Royal Botanic Gardens.
