Oxford University is made up of 39 main 'colleges', many of which are open to visitors (some will charge a small fee). In particular, you might want to explore Christ Church or New College if you're a fan of Harry Potter!

There are a number of University buildings to visit, including the Bodleian Library, Sheldonian Theatre and Radcliffe Camera.

There are a few museums in Oxford, including the Pitt Rivers and Ashmolean - hopefully you'll have enough time to explore the Natural History Museum on Saturday night!

Oxford Castle is the oldest non-religious building in Oxford, and open to the public. You can climb the Castle Tower and enjoy panoramic views over Oxford.

We've put together a short circular walking tour, beginning and ending on Broad Street. The walk is approximately 30 minutes, unless you're planning on stopping and enjoying any of the sights.

1. Starting on Broad Street you can make a quick stop at the White Horse - the smallest pub in Oxford, and where Sarah and Mike first met!

2. Opposite the White Horse pub you will see the Bodleian Library, the main research library for the University and open to the public.

3. With the Bodleian Library on your right, continue down Broad Street and turn right onto Catte Street. On your left is New College Lane where you will see Oxford's Bridge of Sighs.

4. Continue down Catte Street until you reach the Radcliffe Camera - a University library, and the most recognisable landmark in Oxford.

5. Opposite the Radcliffe Camera, also on Catte Street, you will see All Souls College. The college is usually open to visitors, so worth seeing if you can pop your head in.

6. Continuing down Catte Street you will come to the High Street. Turn right and immediately on the corner you will see the University Church of St Mary.

7. With the Church on your right, continue down the High Street. You will eventually see the entrance to the Covered Market on your right.

8. Leave the Covered Market, and continue down the High Street. Turn right onto Cornmarket Street, and continue straight. At the crossroads keep going straight down Magdalen Street, continuing as it becomes St Giles'. Eventually you will reach the Eagle and Child pub where J.R.R. Tolkein wrote the Lord of the Rings books!

9. Leaving the Eagle and Child, cross the road and head up St Giles' back towards Broad Street. On your left you will see St. John's College, often open to visitors.

10. Continue along St Giles' and then turn left back onto Broad Street. Walk past Balliol College and you will see Trinity College next door. Consider having a wander round Trinity if it is open to visitors (alternatively, head back to the White Horse for a final pint).
