The Royal Wedding - Prince William and Catherine Middleton

The wedding of Prince William, Duke of Cambridge, and Catherine Middleton took place on Friday, 29 April 2011 at Westminster Abbey in London.

Prince William, second in the line of succession to Queen Elizabeth II, first met Catherine Middleton in 2001, whilst both were studying at the University of St Andrews. Their engagement on 20 October 2010 was announced on 16 November 2010.

The build-up to the wedding and the occasion itself attracted much media attention, with the service being broadcast live around the world, and being compared and contrasted in many ways with the 1981 marriage of William's parents, Prince Charles and Lady Diana Spencer.

An estimated three billion people watched the wedding across the world and 24.5 million watched the event live in the UK.

Below is a selection of photos and videos from the Wedding Day. Enjoy :-)

Catherine Middleton and her father Michael Middleton met the Dean of Westminster on arrival at Westminster Abbey for her wedding to Prince William, while her maid of honour, Philippa Middleton, sorted out the train of her dress. The newly titled Duchess of Cambridge, who managed to keep her wedding dress a secret, wore an ivory and lace gown by Sarah Burton at Alexander McQueen. The prince wore the red tunic of an Irish Guards colonel - his most senior honorary appointment.

The 1,900 guests comprised friends and family as well as officials, including overseas royals, politicians, military personnel and representatives of various faiths and charities. According to a lip-reading expert, Prince William told his bride she looked "beautiful" as she joined him at the altar.

In line with tradition Prince William placed a Welsh gold wedding ring onto Catherine Middleton's finger. The ring was fashioned by Wartski from a piece of Welsh Gold that was given to Prince William by The Queen shortly after the engagement was announced.

After the couple said their vows, the Archbishop of Canterbury, the Most Reverend Rowan Williams, declared: "I pronounce that they be man and wife together, in the name of the Father, and of the Son, and of the Holy Ghost. Amen."

The Kiss! As Kate and William greeted the crowds from the balcony of Buckingham Palace everyone waited for the kiss. And Will didn't keep us waiting long! Not satisfied the crowd chanted 'one more kiss', so the new Duke and Duchess of Cambridge obliged with big smiles.
