Statue of James II, Trafalgar Square

The Mud Soldier was an artwork by Damian and Killian Van Der Velden (Grofweg Architecten) displayed in Trafalgar Square. It was commissioned to commemorate the 100th anniversary of the Battle of Passchendaele.The sculpture, depicting a First World War soldier seated on a bedroll, was constructed from sand and mud taken from Flanders Fields. Situated in the open air, it was intended to disintegrate over the five days that it was on show. The location was chosen due to the proximity of the homes of two servicemen who had received the Victoria Cross for their actions at Passchendaele.

One & Other was a public art project by Antony Gormley, in which 2,400 members of the public occupied the usually vacant fourth plinth in Trafalgar Square, London, for an hour each for 100 days. The project began at 9 am on Monday 6 July 2009, and ran until 14 October. The first person to officially occupy the plinth was Rachel Wardell from Lincolnshire. A documentary art book by Gormley, entitled One and Other, was published in the UK by Jonathan Cape on 14 October 2010. The Wellcome Trust has posted online at its website its series of oral-history interviews of the 2,400 plinthers.

The Fourth plinth is the northwest plinth in Trafalgar Square in central London. It was originally intended to hold an equestrian statue of William IV, but remained bare due to insufficient funds. For over 150 years the fate of the plinth was debated; in 1998, the Royal Society for the encouragement of Arts, Manufactures and Commerce (RSA) commissioned three contemporary sculptures to be displayed temporarily on the plinth. Shortly afterwards, Chris Smith, Secretary of State for Culture, Media and Sport, commissioned Sir John Mortimer to seek opinions from public art commissioners, critics and members of the public as to the future of the plinth. Mortimer's final report recommended that the commissions remain a rolling programme of temporary artworks rather than settle permanently on one figure or idea to commemorate. In 2003, the ownership of Trafalgar Square was transferred from Westminster City Council to the Mayor of London and this marked the beginning of the Mayor of London's Fourth Plinth Commission as it is now known.

The End (stylised in all caps) is a sculpture by British artist Heather Phillipson, which was installed on the fourth plinth at Trafalgar Square, London, from 2020 to 2022. The sculpture depicted a gigantic dollop of melting whipped cream, topped with a cherry, with a fly and a drone scaling its surface. The drone was fitted with a camera, which sent a live feed of the surrounding area to a dedicated website. Standing 9.4 metres, or nearly 31 feet, in height, the sculpture was the tallest installation to date as part of the Mayor of London's Fourth Plinth Programme, which features a rolling commission of public artworks.

Canada House (French: Maison du Canada) is a Greek Revival building on Trafalgar Square in London. It has been a Grade II* Listed Building since 1970. It has served as the offices of the High Commission of Canada in the United Kingdom since 1925.

The National Gallery is an art museum in Trafalgar Square in the City of Westminster, in Central London, England. Founded in 1824, it houses a collection of over 2,300 paintings dating from the mid-13th century to 1900.The Gallery is an exempt charity, and a non-departmental public body of the Department for Digital, Culture, Media and Sport. Its collection belongs to the government on behalf of the British public, and entry to the main collection is free of charge. In 2020, due to the COVID-19 pandemic it attracted only 1,197,143 visitors, a drop of 50 per cent from 2019, but it still ranked eighth on the list of most-visited art museums in the world.Unlike comparable museums in continental Europe, the National Gallery was not formed by nationalising an existing royal or princely art collection. It came into being when the British government bought 38 paintings from the heirs of John Julius Angerstein in 1824. After that initial purchase, the Gallery was shaped mainly by its early directors, especially Charles Lock Eastlake, and by private donations, which now account for two-thirds of the collection. The collection is smaller than many European national galleries, but encyclopaedic in scope; most major developments in Western painting "from Giotto to Cézanne" are represented with important works. It used to be claimed that this was one of the few national galleries that had all its works on permanent exhibition, but this is no longer the case. The present building, the third to house the National Gallery, was designed by William Wilkins from 1832 to 1838. Only the facade onto Trafalgar Square remains essentially unchanged from this time, as the building has been expanded piecemeal throughout its history. Wilkins's building was often criticised for the perceived weaknesses of its design and for its lack of space; the latter problem led to the establishment of the Tate Gallery for British art in 1897. The Sainsbury Wing, a 1991 extension to the west by Robert Venturi and Denise Scott Brown, is a significant example of Postmodernist architecture in Britain. The current Director of the National Gallery is Gabriele Finaldi.

Cockspur Street is a short street in the City of Westminster, London, SW1 within which a very short part of Trafalgar Square links Charing Cross to Pall Mall/Pall Mall East at the point where that road changes name, opposite the traffic exit from Haymarket.

Trafalgar Square ( trə-FAL-gər) is a public square in the City of Westminster, Central London, established in the early 19th century around the area formerly known as Charing Cross. At its centre a high column bearing a statue of Admiral Nelson commemorates his victory at Battle of Trafalgar, the British naval victory in the Napoleonic Wars over France and Spain that took place on 21 October 1805 off the coast of Cape Trafalgar. The site around Trafalgar Square had been a significant landmark since the 1200s. For centuries, distances measured from Charing Cross have served as location markers. The site of the present square formerly contained the elaborately designed, enclosed courtyard, King's Mews. After George IV moved the mews to Buckingham Palace, the area was redeveloped by John Nash, but progress was slow after his death, and the square did not open until 1844. The 169-foot (52 m) Nelson's Column at its centre is guarded by four lion statues. A number of commemorative statues and sculptures occupy the square, but the Fourth Plinth, left empty since 1840, has been host to contemporary art since 1999. Prominent buildings facing the square include the National Gallery, St Martin-in-the-Fields, Canada House, and South Africa House. The square has been used for community gatherings and political demonstrations, including Bloody Sunday in 1887, the culmination of the first Aldermaston March, anti-war protests, and campaigns against climate change. A Christmas tree has been donated to the square by Norway since 1947 and is erected for twelve days before and after Christmas Day. The square is a centre of annual celebrations on New Year's Eve. It was well known for its feral pigeons until their removal in the early 21st century.

The Canadian Pacific Building at 62–65 Trafalgar Square (formerly 62–65 Charing Cross) is an office building in Westminster in London, England. It was constructed as the London offices of the Canadian Pacific Railway Company and its affiliated steamship line (CP Ships), hotel chain (Canadian Pacific Hotels), and other subsidiary companies. It is faced with Portland stone, features prominent CANADIAN PACIFIC signage, and houses a small clock tower. Until 2011, the building was occupied by commercial and law offices, but it is now under re-development by BMB for conversion into five luxury apartments. The project was completed in 2012, and the historic structure was renamed "Trafalgar One".
