It is 60 years since the Queen, then Princess Elizabeth, married Lieutenant Philip Mountbatten - the first time a British heir presumptive had been married.
The royal couple had eight bridesmaids, including the Queen's sister, Princess Margaret, plus two page boys.
Thousands gathered outside Buckingham Palace to celebrate the royal wedding on 20 November, 1947.
The Queen was the 10th member of the royal family to be married at Westminster Abbey - the first was Henry I, who married Princess Matilda of Scotland there in 1100.
The marriage was entered in the book of register. The many witnesses included the King and Queen, Queen Mary and Princess Andrew of Greece (the groom's mother).
Some 2,000 guests were invited to a special ceremony to mark the royal couple's 60th wedding anniversary.
The couple retraced their steps up the aisle of Westminster Abbey 60 years after their wedding.
The Queen is the first reigning monarch in British history to celebrate his or her diamond wedding.
The couple's grandson, Prince William, gave a reading during the service.
Their German links meant Prince Philip's relatives, Prince and Princess Ludwig and Princess Margaetta of Baden and the Margrave and Margravine of Baden, were not invited in 1947.
The abbey's bells rang out as the Queen and Prince Philip left, to be met by cheering crowds before unveiling a plaque in Parliament Square.
