When you visit, you need to be prepared for pelotons of bicycles, mostly not of the sporty type that you see in the Tour de France, but the ancient sit-up- and-beg variety with a basket for books on the front, and in the saddle an undergraduate in a hurry, or a don in a flowing black cloak. You'll meet them – and hopefully miss them – around every corner. Music: © Barney & Izzi Hardy
