Bryn Terfel and Katherine Jenkins will open and close the event

The annual festival opened its doors on Tuesday, with a concert by Bryn Terfel as the main attraction of the day.

Running from July 4-9, the Eisteddfod will end on Sunday, with a sell-out gala concert by Katherine Jenkins.

Other highlights of the week include International Children's Day, new scores composed for Charlie Chaplin films, and the Pavarotti Trophy.

Bass baritone Terfel - whose concert has also sold out - is making his first appearance at the festival for a decade, while Jenkins will make her debut there.

Peace Prize

She will be accompanied by the National Symphony Orchestra.

The festival of music, song and dance was nominated for a Nobel Peace Prize in 2004 and has previously featured performances from Luciano Pavarotti, Nigel Kennedy, Shirley Bassey, James Galway, Lesley Garrett and Michael Ball.

According to the organisers, more than 500,000 overseas competitors have performed there in 60 years, watched by about three million spectators.

The festival attracts performers from all over the world

Events will be staged throughout the day, with headlining concerts each evening.

On Wednesday, Terry Waite will present the Window on the World opening ceremony.

On Thursday, four Charlie Chaplin's classic silent films will be shown - set to a new score by American composer Carl Davis.

Friday's highlight sees four top Welsh male voice choirs join together in Comrades in Song.

On Saturday, the Pavarotti trophy is the main prize in the Choir of the World competition.
