The 52-m column commemorates Admiral Lord Nelson, Britain’s most famous sea lord, who died heroically at the Battle of Trafalgar in 1805. Edwin Landseer’s four lions guard its base. The north side of the square is now taken up by the National Gallery with Canada House on the west side and South Africa House on the east.

The Mall. This broad triumphal approach from Trafalgar Square to Buckingham Palace  was created by Aston Webb when he redesigned the front of the palace and the Victoria Monument in 1911. The spacious tree-lined avenue follows the course of an old path at the edge of St James’s Park. The path was laid out in the reign of Charles II, when it became London’s most fashionable promenade.
