The Trafalgar Square Christmas tree is a Christmas tree gifted to the people of Britain by Norway each year since 1947. The tree is prominently displayed in Trafalgar Square from the beginning of December until 6 January.

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.

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.

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.

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.

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 statue of James II is a bronze sculpture located in the front garden of the National Gallery in Trafalgar Square, London, United Kingdom. Probably inspired by French statues of the same period, it depicts James II of England as a Roman emperor, wearing Roman armour and a laurel wreath (traditionally awarded to a victorious Roman commander). It originally also depicted him holding a baton. It was produced by the workshop of Grinling Gibbons. The execution was most likely, according to contemporary accounts, the work of the Flemish sculptors Peter van Dievoet and Laurens van der Meulen, rather than of Gibbons himself. The statue has been relocated several times since it was first erected in the grounds of the old Palace of Whitehall in 1686, only two years before James II was deposed.

The statue of George IV in Trafalgar Square, London, is a bronze equestrian statue by Sir Francis Legatt Chantrey. It depicts the King dressed in ancient Roman attire and riding bareback. The sculpture was originally designed to sit on top of the Marble Arch at the entrance to Buckingham Palace, but was placed in its current location following the King's death.

St George's Barracks was a military installation in Orange Street, behind the National Gallery, in London.

The National Portrait Gallery (NPG) is an art gallery in London housing a collection of portraits of historically important and famous British people. It was arguably the first national public gallery dedicated to portraits in the world when it opened in 1856. The gallery moved in 1896 to its current site at St Martin's Place, off Trafalgar Square, and adjoining the National Gallery. It has been expanded twice since then. The National Portrait Gallery also has regional outposts at Beningbrough Hall in Yorkshire and Montacute House in Somerset. It is unconnected to the Scottish National Portrait Gallery in Edinburgh, with which its remit overlaps. The gallery is a non-departmental public body sponsored by the Department for Digital, Culture, Media and Sport.

La Mitrailleuse is a painting by British Futurist artist Christopher Nevinson, made in 1915 while he was on honeymoon leave from service as an ambulance driver with the RAMC on the Western Front in the First World War. In an article in The Burlington Magazine in 1916, artist Walter Sickert called the work "the most authoritative and concentrated utterance on the war in the history of painting". Mitrailleuse is the French word for machine gun, and originated from the mid-19th century French volley gun, the mitrailleuse. The painting shows three soldiers in the trenches wearing metal Adrian helmets, one firing a machine gun. A fourth soldier lies dead beside them. Around them are wooden beams and barbed wire. The subjects are abstracted into angular geometric blocks of colour, becoming dehumanised components in a machine of death. Nevinson later wrote: "To me the soldier going to be dominated by the machine ... I was the first man to express this feeling on canvas." The painting measures 24 × 20 inches (61 × 51 cm). It was exhibited at the Grafton Galleries and Leicester Galleries in 1916, and donated to the Tate Gallery by the Contemporary Art Society in 1917. It is currently exhibited at the Tate Britain.

A bronze statue of Charles James Napier by the sculptor George Gammon Adams stands in Trafalgar Square in London, United Kingdom. It occupies one of the four plinths in Trafalgar Square, the one to the southwest of Nelson's Column.
