The City itself has plenty to see and do (not all of it is Academic!). There is plenty of inspiration for sightseeing at www.visitoxfordandoxfordshire.com.
Coming highly recommended from Diamond staff is the Turf Tavern, the location where, according to legend, Bill Clinton "did not inhale" (that is, if you can find it among the twisty streets!). Meanwhile, for those wanting a taste of British eccentricity, then the Headington Shark is among the more bizarre things to visit in Oxford. It was described by the owner as "Untitled 1986", by Oxford City Council as "a danger to the public", and by The Times as a "splendid lark". Finally, if nothing else takes your fancy, there's always the option to act out your favourite scenes from Harry Potter throughout the City.
