View across Trafalgar Square, City of Westminster, looking northwest. Trafalgar Square was planned as part of the redevelopment of the West Strand Improvements by John Nash following the passing of the Charing Cross Act of 1826. Although it was to be another 30 years before the square was completed, it occupies the area of the former Great Mews of the Crown Stables. Charles Barry was the architect, although he opposed the decision to erect Nelson's Column on the site - he was overruled. The whole square is Grade I listed, number 1001362. Admiral Lord Horatio Nelson's memorial column and sculpture was built 1839-1842, to the design of William Railton with a fluted granite column and Corinthian capital. The statue was by E. H. Baily and the bas-relief panels around the base depicting Nelson's famous naval battles by J. E. Carew, J. Ternouth, M. L. Watson and W. F. Woodington. The four lions by Sir Edwin Landseer were cast by Baron Marochetti and added 1867. The monument is Grade I listed, number 1276052. On the northern side of the square is The National Gallery.
