The Prince of Wales watches a performance at the AGM of the Royal Shakespeare Company at the Swan Theatre in Stratford-Upon-Avon, Warwickshire.
The Prince of Wales celebrated his 66th birthday by cutting a sponge cake with a Shakespearean actor's sword.
His Royal Highness was attending the Annual General Meeting of the Royal Shakespeare Company (RSC) in Stratford-upon-Avon in his capacity as President of the organisation.
The Prince borrowed actor David Rintoul's sword to slice the cake that the company had put on for him.
Among those in the audience were David Suchet, famous for his TV role as Agatha Christie's detective Hercule Poirot, and Booker prize-winning novelist Hilary Mantel.
He watched the performance of an extract of the Bard's early comedy Love's Labour's Lost and Jacobean play The Witch of Edmonton by William Rowley.
The Prince of Wales, President of the RSC cuts a birthday cake with a sword after it was presented to him on his 66th birthday during a visit to the Swan Theatre at the Royal Shakespere Company.
Actors in Elizabethan dress and tights sang happy birthday and presented him with the cake, which he cut to claps and cheers from the audience.
Paying tribute to the actors' "remarkable contribution", The Prince said: "If it wasn't for them we wouldn't have such a great institution as the RSC."
The Prince's birthday was also marked by a 62-gun Royal salute fired from the Tower of London, a 41-gun salute from Hyde Park and a 21-gun salute at Edinburgh Castle.
His Royal Highness is one of only three members of the Royal Family whose birthday is marked with a cannon salute, the others being The Queen and The Duke of Edinburgh.
