In an upcoming documentary, Coronation Girls, King Charles III reflects on his childhood and the time leading up to his mother’s historic coronation. The film centers around 50 Canadian women who attended the late Queen Elizabeth II’s coronation at just 17 years old.

Speaking about his mother's coronation, King Charles has revealed that the late Queen Elizabeth II would often wear the monarch's crown when she was bathing him as a child. The monarch, who was just four years old when his mother became the queen of England, said he had several vivid memories of the run-up to the 1953 ceremony.
