Piccadilly Circus is a road junction and public space of London's West End in the City of Westminster. It was built in 1819 to connect Regent Street with Piccadilly. In this context, a circus, from the Latin word meaning "circle", is a round open space at a street junction.
The Circus now connects Piccadilly, Regent Street, Shaftesbury Avenue, the Haymarket, Coventry Street (onwards to Leicester Square) and Glasshouse Street. It is close to major shopping and entertainment areas in the West End. Its status as a major traffic junction has made Piccadilly Circus a busy meeting place and a tourist attraction in its own right.
