Banqueting House, Whitehall

The Palace of Whitehall – also spelled White Hall – at Westminster was the main residence of the English monarchs from 1530 until 1698, when most of its structures, with the notable exception of Inigo Jones's Banqueting House of 1622, were destroyed by fire. Henry VIII moved the royal residence to White Hall after the old royal apartments at the nearby Palace of Westminster were themselves destroyed by fire. Although the Whitehall palace has not survived, the area where it was located is still called Whitehall and has remained a centre of the British government. White Hall was at one time the largest palace in Europe, with more than 1,500 rooms, overtaking the Vatican, before itself being overtaken by the expanding Palace of Versailles, which was to reach 2,400 rooms. At its most expansive, the palace extended over much of the area bordered by Northumberland Avenue in the north; to Downing Street and nearly to Derby Gate in the south; and from roughly the elevations of the current buildings facing Horse Guards Road in the west, to the then banks of the River Thames in the east (the construction of Victoria Embankment has since reclaimed more land from the Thames)—a total of about 23 acres (9.3 ha). It was about 710 yards (650 m) from Westminster Abbey.

The execution of Charles I by beheading occurred on Tuesday 30 January 1649 outside the Banqueting House on Whitehall. The execution was the culmination of political and military conflicts between the royalists and the parliamentarians in England during the English Civil War, leading to the capture and trial of Charles I. On Saturday 27 January 1649, the parliamentarian High Court of Justice had declared Charles guilty of attempting to "uphold in himself an unlimited and tyrannical power to rule according to his will, and to overthrow the rights and liberties of the people" and he was sentenced to death.Charles spent his last few days in St James's Palace, accompanied by his most loyal subjects and visited by his family. On 30 January, he was taken to a large black scaffold constructed in front of the Banqueting House, where he was to be executed. A large crowd had gathered to witness the regicide. Charles stepped onto the scaffold and gave his last speech, declaring his innocence of the crimes of which parliament had accused him, and claiming himself as a "martyr of the people". The crowd could not hear the speech, owing to the many parliamentarian guards blocking the scaffold, but Charles' companion, Bishop William Juxon, recorded it in shorthand. Charles gave a few last words to Juxon, claiming his "incorruptible crown" in Heaven, and put his head on the block. He waited a few moments and gave a signal; the anonymous executioner beheaded Charles in one clean blow and held Charles' head up to the crowd silently, dropping it into the swarm of soldiers soon after. The execution has been described as one of the most significant and controversial events in English history. Some view it as the martyrdom of an innocent man, with Restoration historian Edward Hyde describing "a year of reproach and infamy above all years which had passed before it; a year of the highest dissimulation and hypocrisy, of the deepest villainy and most bloody treasons that any nation was ever cursed with" and the Tory Isaac D'Israeli writing of Charles as "having received the axe with the same collectedness of thought and died with the majesty with which he had lived", dying a "civil and political" martyr to Britain. Still others view it as a vital step towards democracy in Britain, with the prosecutor of Charles I, John Cook, declaring that it "pronounced sentence not only against one tyrant but against tyranny itself" and Whig historian Samuel Rawson Gardiner, who wrote that "with Charles' death the main obstacle to the establishment of a constitutional system had been removed. [...] The monarchy, as Charles understood it, had disappeared forever".

The Marquess of Lansdowne unveiled the statue on 11 February 1911.

The Earl Haig Memorial is a bronze equestrian statue of the British Western Front commander Douglas Haig, 1st Earl Haig on Whitehall in Westminster, London. It was created by the sculptor Alfred Frank Hardiman and commissioned by Parliament in 1928. Eight years in the making, it aroused considerable controversy; the Field Marshal's riding position, his uniform, the horse's anatomy and its stance all drew harsh criticism. The inscription on the plinth reads 'Field Marshal Earl Haig Commander-in-Chief of the British Armies in France 1915–1918'.

The Ministry of Defence Main Building or MOD Main Building, also known as MOD Whitehall or originally as the Whitehall Gardens Building, is a grade I listed government office building located on Whitehall in London. The building was designed by E. Vincent Harris in 1915 and constructed between 1939 and 1959 on the site of the Palace of Whitehall. It was initially occupied by the Air Ministry and the Board of Trade before in 1964 becoming the current home of the Ministry of Defence. By the 1990s the building was no longer considered fit for purpose and had become expensive to maintain. A major refurbishment was therefore undertaken between 2000 and 2004 through a contract under the private finance initiative.

Whitehall is a road and area in the City of Westminster, Central London. The road forms the first part of the A3212 road from Trafalgar Square to Chelsea. It is the main thoroughfare running south from Trafalgar Square towards Parliament Square. The street is recognised as the centre of the Government of the United Kingdom and is lined with numerous departments and ministries, including the Ministry of Defence, Horse Guards and the Cabinet Office. Consequently, the name 'Whitehall' is used as a metonym for the British civil service and government, and as the geographic name for the surrounding area. The name was taken from the Palace of Whitehall that was the residence of Kings Henry VIII through to William III, before its destruction by fire in 1698; only the Banqueting House has survived. Whitehall was originally a wide road that led to the front of the palace; the route to the south was widened in the 18th century following the destruction of the palace. As well as government buildings, the street is known for its memorial statues and monuments, including the UK's primary war memorial, the Cenotaph. South of the Cenotaph the thoroughfare becomes Parliament Street. The Whitehall Theatre (now the Trafalgar Studios) was formerly associated with a series of farces.

The statue of Alan Brooke, 1st Viscount Alanbrooke by Ivor Roberts-Jones was unveiled in Whitehall, London in 1993.
