Westminster Abbey: In-depth profile
Many royal weddings have taken place here, including current queen Elizabeth II's to Prince Philip in 1947. The Abbey is considered a more modest, but fittingly grand, alternative to the larger St. Paul's Cathedral.
The Archbishop of Canterbury, Rowan Williams, married the couple. The Dean of Westminster conducted the service.
The Bishop of London, Richard Chartres, gave the address. He is a family friend of the Windsors and spoke at Diana, Princess of Wales's memorial in 2007.
William chose his younger brother, Prince Harry, third in line to the throne, as best man. Kate's sister Philippa, often known as Pippa, was her maid of honor.
There were four younger bridesmaids and two younger page boys, including two of William's godchildren.
Who are the bridesmaids and page boys?
Two choirs, one orchestra, a fanfare team and trumpeters played at the wedding:
- The Choir of Westminster Abbey, formed of 20 boys and 12 professional singers. The Abbey's sub-organist played the organ.
- The Chapel Royal Choir, formed of 10 boys and six professional singers.
- The London Chamber Orchestra, the longest established professional chamber orchestra in the UK. Its 39 members played from the organ loft in the Abbey.
- The Fanfare Team from the Central Band of the Royal Air Force, which consists of seven players and their conductor.
- The State Trumpeters of The Household Cavalry, eight trumpeters drawn from the Band of the Life Guards and the Band of the Blues and Royals.
Around 1,900 people were invited to the main ceremony at Westminster Abbey, mainly made up of the couple's friends and family.
The other guests will be members of foreign royal families, heads of state, members of the army, navy and air force and around 80 regular joes from the charities Prince William supports.
