It was at the foothills of Mount Kenya in October 2010, when Prince William asked his university sweetheart, Kate, to become his wife - seven years after they first started dating.
Brits were thrilled, not only at the fact much-loved Kate would finally be an official member of the royal family, but also at the prospect of being able to celebrate a royal wedding.
As we know, Kate - who went on to become the Duchess of Cambridge, accepted the proposal and went on to make history when she became one of the first individuals to marry into the British royal family who wasn't of royal heritage herself, MyLondon reports.
