The sketch of St Andrew's was created by Kate in 2002, when she would have been a student at the University – the place where she met and fell in love with Prince William.
Kate studied art history and graduated with a 2:1 degree in the subject in 2005. While William was enrolled on the same course as his wife in the first year, he later switched to Geography.
