Charing Cross, which is the official centre of London, from which the cab-radius, etc., are measured, and also practically the centre of the London of the sight-seer, is the open space to the S. of Trafalgar Square, between the Strand and Whitehall. The name is probably from the ancient village of Cherringe. Trafalgar Square, one of the finest open spaces in London, contains the Nelson Column and the statues of Sir Henry Havelock, Sir Chas. Napier, George IV., and Gen. Gordon. To the N.E. is the Church of St. Martin’s in the Fields, by Gibbs.
