King Charles last week hosted the first film premiere at a royal palace when a documentary chronicling his lifetime work of championing nature was shown at his historic Windsor Castle home.
Filmed over seven months last year, "Finding Harmony: A King's Vision" is billed as providing a deeply personal insight into the 77-year-old monarch's decades of environmental activism and the philosophy which has motivated him.
The documentary will be available globally to viewers on Amazon Prime from February 6.
Days before its release, Dumfries House's social media account said the royal estate will also feature in "this new landmark documentary from The King's Foundation and Prince Video chronicling the King's lifelong commitment to the environment."
The Instagram account of Dumfries House made the announcement in a social media post featuring King Charles III's photo from the documentary.
Dumfries House in Ayrshire, Scotland, is a royal estate purchased in 2007 by a consortium led by King Charles III, then the Prince of Wales.
Although it is owned by a charitable trust, the estate has a private accommodation for King Charles who stays there during his visits to Scotland.
