Piccadilly Circus is a famous 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. It’s now considered to be the heart of the West End and a well-known meeting point. There’s the famous statue of Eros to one side, and is all overlooked by the famous brightly-lit advertising hoardings.
The closest railway station is Charing Cross, but can be easily accessed by the tube and all other railway stations in London.
