Nelson's Column is a monument in Trafalgar Square in the City of Westminster, Central London, built to commemorate Vice-Admiral Horatio Nelson's decisive victory at the Battle of Trafalgar over the combined French and Spanish navies, during which he lost his life. The monument was constructed between 1840 and 1843 to a design by William Railton at a cost of £47,000 (equivalent to £4,908,873 in 2021). It is a column of the Corinthian order built from Dartmoor granite. The statue of Nelson was carved from Craigleith sandstone by sculptor Edward Hodges Baily. The four bronze lions around its base, designed by Sir Edwin Landseer, were added in 1867.
