‘Finding Harmony: A King’s Vision’ charts King Charles III’s personal journey as an environmentalist throughout his lifetime. This journey is presented through the work of The King’s Foundation, The King’s nature and sustainability charity. Filming for the documentary took place over six months, between January and July 2025. The King took part in two new filming sessions for the documentary, at The King’s Foundation sites Dumfries House and Highgrove Gardens. The documentary was produced by PASSION Planet. The documentary explores The King’s Harmony philosophy – which encourages us to see ourselves as part of nature, not apart from nature. Harmony aims to readdress our relationship with the environment and nature for the good for people, places and the planet. The ideas of Harmony were first crystallised in a 2010 book of the same name, with the subtitle ‘a new way of looking at the world’
