A look back at Prince Charles and Princess Diana's iconic wedding

Though their marriage would end in divorce in 1996, the wedding of Prince Charles and Princess Diana had all the makings of a fairytale. <p>The Prince announced his engagement to 19-year-old aristocrat Diana Spencer on February 24, 1981. The Queen's eldest son had proposed with a diamond and sapphire ring during a private dinner at Buckingham Palace. Decades later, the couple's son Prince William would pop the question to his longtime love Kate Middleton, now the Duchess of Cambridge, with the same beautiful gem. <p>Photo: © Tim Graham/Getty Images</p>
On July 29, 1981, Diana became the first British citizen to marry an heir to the British throne in 300 years. The couple were married at St. Paul's Cathedral in London. <p>Photo: © Serge Lemoine/Hulton Archive/Getty Images</p>

The royal couple had 27 wedding cakes for their big day — however, the official cake, which stood over five-feet tall, was made by David Avery, the head baker of the Naval Armed Forces. The cake featured Charles' coat of arms in addition to Diana's family crest and their first name initials. The impressive dessert was topped off with roses, lilies of the valley and orchids. <p>Photo: © Princess Diana Archive/Getty Images</p>
