Prince Charles and Princess Diana Wedding Photos

Diana enters Buckingham Palace surrounded by the young bridesmaids and pageboys. Around 3,500 guests attended their July 29 nuptials back in 1981.

In her arms, Diana cradles Clementine Hambro, who, at just 5 years old, was her youngest bridesmaid.

Unlike the rest of the girls, Hambro was Diana's choice – she was a favorite pupil of Diana's at the Young England kindergarten, where she taught before she was married.

Dubbed the "wedding of the century," Charles and Diana's nuptials were attended by the royal family at home, and others abroad. Here, the Queen Mother looks on as Diana and Charles speak with their attendants.

Both the Spencer and Windsor-Mountbatten family filled the Buckingham Palace throne room before the staged portraits were shot.
