Gold Hill, Shaftesbury.
This street was featured in the famous Hovis TV advertisement which has been voted the favourite TV advert of all time. It's actually an excerpt from "Boy and Bicycle" - Ridley Scott's first film made while he was a student at the Royal College of Art. The boy featured in the advert walking up the hill was his younger brother. Scott went on to direct the films Alien and Blade Runner amongst others.
