Oxford is famous for its ancient University, the second oldest in the world dating back to the 13th Century. It counts alumni such as JRR Tolkien, CS Lewis, and Lewis Carroll, and modern-day scientists like Tim Berners and the late Stephen Hawking. But what really excites visitors are the tight, traffic-free, atmospheric streets of this typical English town or city. With its honey-coloured stone buildings and cobbled streets, Oxford is compact enough to walk round in a morning, with a visit to a college or the University itself. It also draws Harry Potter fans from around the world.
