Montagu House, Whitehall

Craig's Court is a courtyard off Whitehall in central London containing the grade II* listed Harrington House (c.1692), other listed buildings, and the British Telecom Whitehall telephone exchange of which Harrington House forms a part. It was built by Joseph Craig in the late 1690s on land that had once been the location of the Hermitage of St Katherine. The Court is entered through a narrow single-track road in which the carriage of the Speaker of the House of Commons once got stuck and which is often overlooked by tourists. The Sun Fire Office had offices there from 1726 and army agents Cox & Company were located there for over 150 years. Former residents include the memoirist Teresia Constantia Phillips (1748–49) and the painter George Romney in the 1760s, but the only remaining original building is Harrington House.

In advance of the wedding of the Princess Elizabeth and Lieutenant Philip Mountbatten, RN, Duke of Edinburgh, which took place on 20 November 1947 at Westminster Abbey, the Home Civil Service and Foreign Service undertook a collection for the purpose of purchasing a suitable present to celebrate the royal nuptials. Two silver salvers were purchased, after which the balance of the Wedding Fund collected by the Home Civil Service and the Foreign Service was £14,037.The Princess Elizabeth was touched by the kindness of the gesture and made her wish known that the balance should be handed over with the express intention that it be utilised to establish a social facility for civil servants: ‘on condition that membership should be available to all grades and classes at a subscription within reach of all.’ A suitable premises was found at 13-15 Great Scotland Yard and the Civil Service Club in Great Scotland Yard was brought into being as a social centre for all civil servants, both serving and retired, and opened its doors on the morning of 2 February 1953 where it continues to operate to this day.

The Great Smog of London, or Great Smog of 1952, was a severe air pollution event that affected London, England, in December 1952. A period of unusually cold weather, combined with an anticyclone and windless conditions, collected airborne pollutants—mostly arising from the use of coal—to form a thick layer of smog over the city. It lasted from Friday 5 December to Tuesday 9 December 1952, then dispersed quickly when the weather changed.The smog caused major disruption by reducing visibility and even penetrating indoor areas, far more severely than previous smog events, called "pea-soupers". Government medical reports in the weeks following the event estimated that up to 4,000 people had died as a direct result of the smog and 100,000 more were made ill by the smog's effects on the human respiratory tract. More recent research suggests that the total number of fatalities may have been considerably greater, with estimates of between 10,000 and 12,000 deaths.London had suffered since the 13th century from poor air quality and diarist John Evelyn had written about "the inconveniencie of the aer and smoak of London" in Fumifugium, the first book ever written about air pollution, in 1661. However, the Great Smog was many times worse than anything the city had ever experienced before: it is thought to be the worst air pollution event in the history of the United Kingdom, and the most significant for its effects on environmental research, government regulation, and public awareness of the relationship between air quality and health. It led to several changes in practices and regulations, including the Clean Air Act 1956.

The 1962 London smog was a severe smog episode that affected London, England in December 1962. It occurred ten years after Great Smog of London, in which serious air pollution had killed as many as 12,000 people. While the 1952 smog had led to the passing of the 1956 Clean Air Act, which restricted the burning of domestic fuels in urban areas with the introduction of smokeless zones, fogs continued to be smoky in London for some years after the act as residents and operators were given time to convert from domestic fuels. The December 1962 smog is thought to have led to the deaths of up to 700 people.

The War Office was a department of the British Government responsible for the administration of the British Army between 1857 and 1964, when its functions were transferred to the new Ministry of Defence (MoD). It was equivalent to the Admiralty, responsible for the Royal Navy (RN), and (much later) the Air Ministry, which oversaw the Royal Air Force (RAF). The name 'War Office' is also given to the former home of the department, located at the junction of Horse Guards Avenue and Whitehall in central London. The landmark building was sold on 1 March 2016 by HM Government for more than £350 million, on a 250 year lease for conversion into a luxury hotel and residential apartments. Prior to 1855, 'War Office' signified the office of the Secretary at War. In the 17th and 18th centuries, a number of independent offices and individuals were responsible for various aspects of Army administration. The most important were the Commander-in-Chief of the Forces, the Secretary at War, and the twin Secretaries of State; most of whose military responsibilities were passed to a new Secretary of State for War in 1794. Others who performed specialist functions were the controller of army accounts, the Army Medical Board, the Commissariat Department, the Board of General Officers, the Judge Advocate General of the Armed Forces, the Commissary General of Muster, the Paymaster General of the forces, and (particularly with regard to the Militia) the Home Office.The term War Department was initially used for the separate office of the Secretary of State for War; in 1855, the offices of Secretary at War and Secretary of State for War were amalgamated, and thereafter the terms War Office and War Department were used somewhat interchangeably.

The Constitutional Club was a London gentlemen's club, now dissolved, which was established in 1883 and disbanded in 1979. Between 1886 and 1959 it had a distinctive red and yellow Victorian terracotta building, designed by Robert William Edis, at 28 Northumberland Avenue, off Trafalgar Square.
