London, England (CNN) -- Britain's Prince William and his bride-to-be Kate Middleton, returned to the scene of their early romance Friday, visiting St. Andrews University in Fife, Scotland.
As patron of the university's 600th Anniversary Appeal, Prince William officially launched the event, viewing the surviving Papal Bull -- a series of letters issued by the pope in 1413 -- and unveiling a plaque in front of students and staff.
Prince William, who is second line to the British throne, studied art history at St. Andrews when he first met Kate in 2001. The pair grew closer after moving into a shared house with two other friends and were said to have started dating in late 2003. They both graduated in 2005.
"Catherine might be a bit emotional today," said CNN royal contributor Mark Saunders. "She came here (St. Andrews) as just as a normal student and she comes back today as a woman who will one day sit on the throne of England. CNN
