Description: Trafalgar Square is a square in central London that commemorates the Battle of Trafalgar (1805), a British naval victory of the Napoleonic Wars. The original name was to have been "King William the Fourth's Square", but George Ledwell Taylor suggested the name "Trafalgar Square". The area had been the site of the King's Mews since the time of Edward I. In the 1820s the Prince Regent engaged the landscape architect John Nash to redevelop the area. Nash cleared the square as part of his Charing Cross Improvement Scheme. The present architecture of the square is due to Sir Charles Barry and was completed in 1845. The square consists of a large central area surrounded by roadways on three sides, and stairs leading to the National Gallery on the other. The roads which cross the square form part of the busy A4 road, and prior to 2003, the square was surrounded by a one-way traffic system on all sides. Underpasses attached to Charing Cross underground station still allow pedestrians to avoid traffic. Recent works have reduced the width of the roads and closed the northern side of the square from traffic. Nelson's Column is in the centre of the square, surrounded by fountains and four huge bronze lions sculpted by Sir Edwin Landseer; the metal used is said to have been recycled from the cannon of the French fleet. The column is topped by a statue of Lord Nelson, the admiral who commanded the British Fleet at Trafalgar.
