Piccadilly explores how the area has been shaped by social and historical events - from female suffrage to world wars to technological advancements - and by its colourful cast of characters - from flower girls, shop assistants and sex workers, to film stars, Bright Young Things and conmen (and women).
For many, the Circus has represented both a home from home and a brave new world, as campaigners, revellers, opportunists and romantics have all been drawn to Piccadilly's bright lights.
This is the story of why Piccadilly Circus continues to mean so much to so many.
