Remembering Princess Diana's royal wedding

Princess Diana and Prince Charles' Royal Wedding

Lady Diana Spencer married Charles, Prince of Wales 34 years ago today, at St. Paul's Cathedral in London on July 29, 1981. The wedding was a momentous occasion not only for the couple and the royal family, but also for the people of England, who adored Diana.

The pair were officially engaged on February 24, 1981, and Lady Diana's engagement ring was an oval blue sapphire surrounded by smaller diamonds. The ring has since been passed down to Kate Middleton, Diana's daughter in-law and the current Duchess of Cambridge.

The couple opted for a grand ceremony, with 3,500 guests in attendance. Diana's exquisite ivory dress was designed by Elizabeth and David Emanuel and was made of silk taffeta and lace.

5 Fun facts about the 1981 royal wedding:

1. The prince and princess had 27 wedding cakes!

2. Nancy Reagan, who was first lady of the United States at the time, was among the guests, as was UK Prime Minister Margaret Thatcher.

3. It is estimated that 1 billion people around the world watched the wedding on television.

4. According to Princess Diana's brother, the tiara that she wore for the wedding gave her a terrible headache. Ouch!

5. According to Us magazine, the designer's of Di's wedding dress were so concerned about the press finding out what her dress looked like that they had a back-up dress ready in case they needed to make a last-minute switch.
