What will happen in The Coronation?
The Queen will be interviewed by Coronation expert Bruce about the day she became the monarch of Great Britain.
She will share her memories of the day but also of her father King George VI and his own coronation in 1937.
The monarch also discusses the significance of the Crown Jewels in the coronation.
She will also talk about the historical context of her coronation, which saw her becoming Queen at the age of 27 and was charged to lead a nation forward following two world wars.
The Queen had to take to the throne following the untimely death of her father and hadn’t expected to be coronated for at least another 20 years.
“I’ve seen one Coronation, and been the recipient in the other, which is pretty remarkable,” the Queen remarks as Bruce questions her.
The Coronation will feature archive footage from the event and also private film material.
There will be eyewitness accounts of those who were involved in the coronation such as a maid of honour who nearly fainted in Westminster Abbey during the ceremony.
As well as a 12-year-old choirboy, who was left to sing solo after the rest of the singers were overwhelmed into silence by the magnanimous event.
The Coronation airs on BBC One tonight at 8pm.
