Arthur's was a London gentlemen's club, now dissolved, which was established in 1811 and was disbanded in 1940. Between 1827 and 1940 it was based at 69 St James's Street. It is now best remembered for having built the London clubhouse currently occupied by the Carlton Club. The club was first formed at a meeting at a bank at 16 St James's Street on 8 May 1811, with the resolution 'That a New Club be forthwith established, to consist of 300 Members.' The club is notable for being the first to be a members' club wholly owned by the members, as opposed to the proprietary clubs which previously existed, like White's, Boodle's, and Brooks's, and it accordingly served as the mould for most of the nineteenth century members'-owned clubs which followed.

The Carlton Club is a private members' club in St James's, London. It was the original home of the Conservative Party before the creation of Conservative Central Office. Membership of the club is by nomination and election only.

On 26 June 1990, the Provisional IRA detonated a bomb at the Carlton Club, a club in London popular among MPs and supporters of the ruling Conservative Party. The bombing injured 20 people, one of whom, Lord Kaberry of Adel, died a year later. The ground floor collapsed to the basement and windows were shattered. The blast was felt up to half a mile away. In a statement, the IRA said: "Like Brighton in 1984, the IRA has brought the war directly to those who keep the British Army on the streets and in the fields of Ireland. While such occupation continues, and the Nationalist people face daily oppression, the policy makers and their military arm will not be safe." The attack was part of the IRA's escalating campaign that started in early 1990 and which had claimed two lives and 27 injuries since May that year. Tory MP for Fulham Matthew Carrington called the attack very "worrying" as it was a non-military target, suggesting a dangerous tactic from the IRA against members of the public.The bomb contained 15 lb (6.8 kg) of Semtex explosives. Prime Minister Margaret Thatcher arrived at the club shortly after the bombing and spoke with some of the victims.

York House is a historic wing of St James's Palace, London, built for Frederick, Prince of Wales, on his marriage in 1736. It is in the north-western part of the palace on the site of a former suttling-house (canteen) for the Guards; it overlooks Ambassadors' Court and Cleveland Row to the west of the old Chapel Royal. Prince Frederick occupied it for about a year, until his quarrel with the his father drove him from Court. In 1795, Princess Caroline resided here before her marriage with the Prince of Wales, afterwards George IV. Prince Ernest Augustus, Duke of Cumberland, subsequently King of Hanover, lived here for a great many years; and the Duchess of Cambridge was identified with it from 1851 until her death in 1889. Later occupants included the future George V, the late Duke and Duchess of Gloucester from 1936 to 1970, and Princes Charles, William and Harry, who used it before moving to Clarence House.As Edward, Prince of Wales, the future Edward VIII lived at York House, before his refurbishment of Fort Belvedere in Windsor Great Park.The building includes a suite of somewhat low-pitched rooms on the ground-floor, several drawing-rooms on the first floor, a corridor in the rear, and the servants' rooms on the top storey; all facing Cleveland Row. The ceilings of the top floor are low, height having been sacrificed to that of the drawing-room floor; during the nineteenth century this was a common practice in London mansions. The name York House has been used at various times for other houses occupied by various Dukes of York, including those now known as Cumberland House, Dover House, Lancaster House and The Albany.
