About Cambridge
Learn more about the host city, Cambridge.
Cambridge is a university city in Cambridgeshire in England. It is a city of crocuses and daffodils on the Backs, of green open spaces and cattle grazing only 500 yards from the market square. Cows sometimes wander into the market area, since they are not fenced in. The Cambridge of Brooke, Byron, Newton and Rutherford, of the summer idyll of punts, 'bumps', cool willows and May Balls is worth seeing.
