The origins of the name "Piccadilly" relate to a humble 17th-century tailor from the Strand named Robert Baker who sold picadils—a stiff ruffled collar all the rage in courtly circles—and built a house with the proceeds. Snobs dubbed his new-money mansion Piccadilly Hall, and the name stuck.
Pride of place in the circus—a circular junction until the construction of Shaftesbury Avenue in 1886— belongs to the statue of Eros, dating from 1893 (although even most Londoners don't know that it is, in reality, a representation of Eros's brother Anteros, the Greek God of requited love). The other instantly recognizable feature of Piccadilly Circus is the enormous bank of lit-up billboards on the north side; if you're passing at night, frame them behind the Tube entrance sign on the corner of Regent Street for an unforgettable photo.
