Formerly known as Portugal Street, Piccadilly was renamed in the 17th Century.
Robert Baker made his fortune on The Strand selling piccadills (also called picadils or pickadils) – stiff collars with scalloped edges and a broad lace or perforated border. His grand mansion to the fashionable west of the metropolis was soon dubbed Piccadill (later Piccadilly) Hall.
