This year marks the 65th anniversary of Queen Elizabeth II's coronation in 1953.
To commemorate the historic milestone, her Royal Majesty is opening up and sharing her memories from the unforgettable day that changed her life as part of the Royal Collection Season, a new BBC One and Royal Collection Trust television series.
The series kicks off with "Coronation," a one-hour episode that will explore the story of the Crown Jewels and the ceremony that passes the kingdom's highest title from one monarch to the next. The TV event will include both private and official film footage of the ceremony, as well as the coronation of Queen Elizabeth's father, King George VI, in 1937.
"I've seen one coronation, and been the recipient in the other, which is pretty remarkable," the Queen says in the film.
Queen Elizabeth became the head of the monarchy at the age of 27 on June 2, 1953, with millions watching as she was crowned at Westminster Abbey.
According to BBC, the film also features eyewitness accounts of those who participated in the coronation, including a maid of honor who nearly fainted in the Abbey, and a 12-year-old choirboy who was left to sing solo when his overwhelmed colleagues lost their voices.
The Queen's early life and struggles are currently being documented in Netflix's Emmy-winning series, The Crown. ET caught up with Claire Foy, who portrays the Queen on screen, in October, where she opened up about the second season and passing on the torch to Olivia Colman, who will take over the role in season three to continue the Queen's story.
