The decision to build the monument was taken by Dublin Corporation in the euphoria following Nelson's victory at the Battle of Trafalgar in 1805. The original design by William Wilkins was greatly modified by Francis Johnston, on grounds of cost. The statue was sculpted by Thomas Kirk. From its opening on 29 October 1809 the Pillar was a popular tourist attraction, but provoked aesthetic and political controversy from the outset. A prominent city centre monument honouring an Englishman rankled as Irish nationalist sentiment grew, and throughout the 19th century there were calls for it to be removed, or replaced with a memorial to an Irish hero.
