Bounded by Piccadilly Circus, Leicester Square, Charing Cross Road, Oxford Street and Regent Street, Soho was known as the lair of criminals… and of the French. Today, Soho is a centre for nightlife with its clubs, bars and pubs; as such it is an area most pleasantly explored by day. Successive waves of immigration have given it a cosmopolitan feel and, in Soho Square and its vicinity, 18C and 19C houses still survive.
