It marks the irregular intersection of several busy streets, including Piccadilly, Regent, Haymarket, and Shaftesbury Avenue. It is actually square in shape, even though it was originally given the Roman name – Circus – for a circle.
It is one of London’s busiest hubs and traffic junctions, with large billboards that call to mind Times Square in New York (well, being from Jersey, it;s meh)
Piccadilly Circus is the meeting place of five busy roads and is the center of London's hustle and bustle. Notable streets leading off Piccadilly Circus include Regent Street, a major shopping thoroughfare; Shaftesbury Avenue, at the heart of Theatreland; and Piccadilly itself. The surrounding districts are Soho, Leicester Square, Trafalgar Square, St James’s, and Mayfair.
Whether it's people on their way to work in the morning, shoppers en route to the chain store-lined Oxford Street (just a few blocks north) or lively club and bar hoppers passing through at night, Piccadilly is always thrumming with activity.
