Trafalgar Square is owned by the Queen in Right of the Crown[a] and managed by the Greater London Authority, while Westminster City Council owns the roads around the square, including the pedestrianised area of the North Terrace. The square contains 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, a major road running west of the City of London. 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 between 1937 and 1939 (replacements for two of Peterhead granite, now in Canada) and guarded by four monumental bronze lions sculpted by Sir Edwin Landseer. At the top of the column is a statue of Horatio Nelson, who commanded the British Navy at the Battle of Trafalgar.
Surrounding the square are the National Gallery on the north side and St Martin-in-the-Fields Church to the east. Also on the east is South Africa House, and facing it across the square is Canada House. To the south west is The Mall, which leads towards Buckingham Palace via Admiralty Arch, while Whitehall is to the south and the Strand to the east. Charing Cross Road passes between the National Gallery and the church.
London Underground's Charing Cross station on the Northern and Bakerloo lines has an exit in the square. The lines had separate stations, of which the Bakerloo line one was called Trafalgar Square until they were linked and renamed in 1979 as part of the construction of the Jubilee line, which was rerouted to Westminster in 1999. Other nearby tube stations are Embankment connecting the District, Circle, Northern and Bakerloo lines, and Leicester Square on the Northern and Piccadilly lines.
London bus routes 3, 6, 9, 11, 12, 13, 15, 23, 24, 29, 53, 87, 88, 91, 139, 159, 176, 453 pass through Trafalgar Square.
A point in Trafalgar Square is regarded as the official centre of London in legislation and when measuring distances from the capital.
