To celebrate his 70th birthday, Charles is displaying some of his most treasured and never-before-seen photographs, paintings and belongings, sharing them with the public.
One of the highlights is the adorable photo of a baby Prince George sleeping in the arms of Charles, whilst proud dad Prince William looks on. The snap comes just days before George celebrates his fifth birthday on July 22.
The photo is usually kept at Charles' country home Highgrove.
Charles' love for his family is evident throughout the exhibition, with photos from Prince Harry and Meghan Markle's wedding day on display, as well as a photo of Harry and Charles after Harry flew his father in an Apache helicopter while he was training, and a snap from George's christening.
The palace is open from July 21 until September 30 and visitors can also see 19 state rooms as part of the tour. So if you happen to be in London, it's something you don't want to miss!
