Prince William and Kate Middleton attended a charity gala in London to mark the 600th anniversary of St Andrews University, the Alma Mater of both the Duke and Duchess of Cambridge. St Andrew's University also happens to be the place where William and Kate first met each other. Prince William and Catherine graduated, with honours, in 2005 – William in Geography and Kate in History of Art.

Founded in 1413, St Andrews is Scotland's oldest university and the third oldest university in the English-speaking world, behind Oxford and Cambridge.

To commemorate 600 years of the institution, William and Kate attended a fundraising charity dinner at Middle Temple Inn on 8 November. Catherine, the Duchess of Cambridge opted to yet again recycle her wardrobe. Kate wore the same floor-length black and cream lace gown she wore to the UK premiere of the film War Horse in London in January. However, the Duchess did make sure she didn't carry the same clutch this time.

"Tonight is very special for Catherine and me," said Prince William in his speech on the occasion, "We have been privileged to receive the best of university educations. Secondly, we all love St Andrews. We love it for the academic start in life it gives us. But perhaps most important of all, we love it for the friendships it has given us."

The University of St Andrews will stretch the celebration of its 600th anniversary across three calendar years - from 2011 to 2013. The royal couple's fundraising was to raise money for the 600th Anniversary Scholarship Fund, which will create opportunities for those students who have limited financial resources.

The charity dinner was not the first event William and Kate would have had occassion to relive memories of their college days at St Andrews. In February last year, the royal couple visited the university as official royals, soon after their engagement, to launch the university's anniversary campaign.
