The square consists of a large central area with roadways on three sides, and a terrace to the north, in front of the National Gallery. The roads around the square form part of the A4 road.The square was formerly surrounded by a one-way traffic system, but works completed in 2003 reduced the width of the roads and closed the northern side to traffic.
Nelson's Column is in the centre of the square, flanked by fountains designed by Sir Edwin Lutyens in 1937-9 as replacements for two earlier fountains of Peterhead granite (now in Canada), and guarded by four monumental bronze lions sculpted by Sir Edwin Landseer. The column is topped by a statue of Horatio Nelson, the vice admiral who commanded the British Fleet at Trafalgar.
On the north side of the square is the National Gallery and to its east St Martin-in-the-Fields church. The square adjoins The Mall entered through Admiralty Arch to the southwest. To the south is Whitehall, to the east Strand and South Africa House, to the north Charing Cross Road and on the west side Canada House.
