On Tuesday, Prince William and Kate Middleton announced their intention to marry at Britain's Westminster Abbey on April 29. The couple shared news of their engagement just last week, with William giving Kate his mother's sapphire engagement ring.
Of course, this won't be Westminster's first royal wedding. Princess (now Queen) Elizabeth herself married Prince Philip of Greece at the church on Nov. 20, 1947. And Elizabeth's parents, King George VI and Queen Elizabeth (then the Duke and Duchess of York) married at Westminster in 1923. Prince Andrew -- Elizabeth's second son -- married Sarah Ferguson there in 1986 (though the couple divorced a decade later). Andrew's sister, Princess Anne, also walked the Westminster aisle in 1973 only to divorce in 1992.
King Henry I seems to have been the first royal to hold his nuptials at Westminster. He married Princess Matilda of Scotland there on Nov. 11, 1100 after a council of bishops determined that Matilda was not, as suspected, a nun but had only lived in a convent to protect herself "from the lust of the Normans." King Henry I is also noted for holding the record for acknowledging more than 20 illegitimate children, which surely would have made him the talk of his age's tabloid press. Sadly, the printing press did not arrive in Europe until around the year 1440.
William's parents, Prince Charles and the then Lady Diana Spencer married on July 29, 1981 at London's St. Paul's Cathedral.
