The Queen will share memories of her coronation in 1953 with royal commentator Alastair Bruce to mark the 65th anniversary of the ceremony.
The Coronation explores the story of the Crown Jewels, revealing to a new generation the ancient ceremony for which they are used.
As part of the Royal Collection Season on the BBC, the hour-long programme also sees the monarch discuss the coronation of her father, George VI, which she watched in 1937.
“I’ve seen one coronation, and been the recipient in the other, which is pretty remarkable,” she says.
BBC Director of Content Charlotte Moore, said: “In her own words the Queen will bring to life the enduring symbolic importance of the coronation ceremonies for modern audiences to enjoy.”
The documentary will also explain the contemporary relevance of the Crown Jewels that are associated with the ceremony. They consist of 140 items, containing 23,000 precious stones and form part of the Royal Collection.
The Coronation is a joint partnership between the BBC and Royal Collection Trust and will be screened on BBC One on 14 January at 8pm.
