Harry Potter's Diagon Alley
Harry Potter was filmed here - up Diagon Alley!
On the north side of Trafalgar Square is Duncannon Street.
Go north and turn right into St.Martins Lane. Continue along the lane for a short time until you see 'Cecil Court' on the left.
You have now arrived at Diagon Alley of the Harry Potter film.
Halfway along on the right of the Court is a shop that specialises in bank notes. They sell a series of five notes with Harry Potter and friends printerd on them.
