Harry Potter sites in England?

Going to England (Cotswolds) with family in a week. Would like to take 13 yr. old daughter (big Potter fan) to see any sites where movies were filmed. Any advise on where there are?

You can probably see quite a few locations from the Cotswolds:

Australia House, The Strand, London (Gringott’s Bank)
Alnwick Castle, Northumberland (Hogwarts, outside scenes)
Bodleian Library, Oxford (Hogwarts interiors)
Martins Heron, Berkshire (Privet Drive)
Christ Church, Oxford (Hogwarts interiors)
Durham Cathedral (Hogwarts interiors)
Gloucester Cathedral (Hogwarts corridors)
Goathland railway station, Yorkshire (Hogsmeade Station)
Kings Cross Station, London (Kings Cross interior)
Lacock Abbey, Wiltshire (Hogwarts interiors)
Leadenhall Market, London (Diagon Alley)
London Zoo (Reptile House)
St Pancras railway station, London (Kings Cross exterior)

If you google. there are a lot of tours that will take you to the places in the stories; from the Cotswolds, I’d say the nearest are Oxford and Gloucester. Also, have a look at the Harry Potter sites for locations:
