The college that has educated thirteen of the country's prime ministers is undoubtedly a must in Oxford, a place of superlatives. The biggest quad, the biggest hall, the biggest library, the biggest gate tower with the loudest bell that tolls 101 times every night at five minutes past nine... And if that is not enough there is also the cloister,the meadow buildings, the bowler-hatted guards, Alice and the Mad Hatter, Henry VIII.... With all these things who needs Harry Potter?
