The Clarence Club, formerly known as the Literary Union Club, was a gentlemen's club founded in 1826, as a socially exclusive dining society that met in Conduit Street, Mayfair, by the poet Thomas Campbell, with the objective of the facilitation of social connections between those with an interest in the arts, philosophy, finance, trade, business, and science. Most of its members were English, but, originally, it included a significant core of members of Scottish descent. It is notable for its prohibition, then radical, of the extension of membership to any member of the press. In 1829, it occupied premises in Regent Street, renamed itself the Literary Union Club, and revised its membership statutes to make it less exclusive. It had over 700 members by 1831. After membership became too numerous, it subsequently renamed itself again, as the Clarence Club, occupied 12 Waterloo Place, Pall Mall and limited its membership to 600. It was dissolved in April 1834. Campbell's Literary Association of the Friends of Poland, founded in 1831, took most of its membership from the Clarence Club.

Charles II Street is a street in St James's in the City of Westminster, London. It runs roughly west to east, starting from the middle of the east side of St James's Square, crossing Regent Street where it becomes Waterloo Place, and ending at Haymarket. At its eastern end it is joined by St Alban's Street on its north side and the Royal Opera Arcade which runs south to join Pall Mall. The street, originally known as Charles Street, was built by about 1665, and the first recorded mention is in 1672. Until 1818, when it was extended to join the Haymarket, Charles Street terminated at (the former) Market Lane. Access to the Haymarket was only available via the courtyard of the Bell Inn.The Security Service (MI5) was based at 16 Charles Street from 1916 to 1919. The road was renamed Charles II Street in 1939.

The Travellers Club is a private gentlemen's club situated at 106 Pall Mall in London, United Kingdom. It is the oldest of the surviving Pall Mall clubs and one of the most exclusive, having been established in 1819. It was described as "the quintessential English gentleman's club" by the Los Angeles Times in 2004.

Pall Mall is a street in the St James's area of the City of Westminster, Central London. It connects St James's Street to Trafalgar Square and is a section of the regional A4 road. The street's name is derived from pall-mall, a ball game played there during the 17th century, which in turn is derived from the Italian pallamaglio, literally ball-mallet. The area was built up during the reign of Charles II with fashionable London residences. It is known for high-class shopping in the 18th century until the present, and gentlemen's clubs in the 19th. The Reform, Athenaeum and Travellers Clubs have survived to the 21st century. The War Office was based on Pall Mall during the second half of the 19th century, and the Royal Automobile Club's headquarters have been on the street since 1908.

Norfolk House, 31 St James's Square, Westminster, was built between 1748 and 1752 as his London townhouse by Edward Howard, 9th Duke of Norfolk (1686–1777) to the design of Matthew Brettingham (1699–1769), "the Elder", and was demolished in 1938. His country house and main seat was Worksop Manor in Nottinghamshire. Norfolk House was built on a site formerly occupied by two houses, namely St Albans House, the residence of the Earl of St Albans (purchased by Thomas Howard, 8th Duke of Norfolk in 1722), and the other the residence of John Belasyse, 1st Baron Belasyse (1614–1689) (purchased by the 9th Duke of Norfolk in 1748). Both these houses were demolished in 1748 by the 9th Duke of Norfolk in preparation for his new house.

The Athenaeum is a private members' club in London, founded in 1824. It is primarily a club for men and women with intellectual interests, and particularly (but not exclusively) for those who have attained some distinction in science, engineering, literature or the arts. Humphry Davy and Michael Faraday were the first chairman and secretary and 51 Nobel Laureates have been members.The clubhouse is located at 107 Pall Mall at the corner of Waterloo Place. It was designed by Decimus Burton in the Neoclassical style, and built by the company of Decimus's father, James Burton, the pre-eminent London property developer. Decimus was described by architectural scholar Guy Williams as "the designer and prime member of the Athenaeum, one of London's grandest gentlemens' [sic] clubs".The clubhouse has a Doric portico, above which is a statue of the classical goddess of wisdom, Athena, from whom the club derives its name. The bas-relief frieze is a copy of the frieze of the Parthenon in Athens. The club's facilities include an extensive library, a dining room known as the coffee room, a Morning Room, a drawing room on the first floor, a restored smoking room (smoking is no longer permitted) on the upper floor, and a suite of bedrooms.

The statue of Sidney Herbert, 1st Baron Herbert of Lea is an outdoor sculpture in London, United Kingdom. Created by J. H. Foley, it was erected by public subscription in 1867 and was originally placed in the courtyard of Cumberland House, Pall Mall (which at the time was the headquarters of the War Office). It moved with the War Office to Whitehall in 1906, where it was placed (out of public sight) in the courtyard of the new War Office building; but eight years later it was moved again to Waterloo Place to stand alongside the Crimean War Memorial, where it is paired with a statue of Herbert's friend and fellow reformer Florence Nightingale.

British Columbia House is a Grade II listed building at 1 and 3, Regent Street, Westminster, London.Designed by architect Alfred Barr, British Columbia House was constructed in 1914 as the premises of the Agent-General of the Province of British Columbia, a position then held by John Herbert Turner. At the time of the building's official opening, in 1915, Turner had been replaced by Richard McBride, but McBride's death, in 1917, saw him return to the Agent-General's role.The building is owned by the Crown Estate and is now a commercial building. It underwent a £8.5 million refurbishment in 2013.

The Reform Club is a private members' club on the south side of Pall Mall in central London, England. As with all of London's original gentlemen's clubs, it comprised an all-male membership for decades, but it was one of the first all-male clubs to change its rules to include the admission of women on equal terms in 1981. Since its founding in 1836, the Reform Club has been the traditional home for those committed to progressive political ideas, with its membership initially consisting of Radicals and Whigs. However, it is no longer associated with any particular political party, and it now serves a purely social function. The Reform Club currently enjoys extensive reciprocity with similar clubs around the world. It attracts a significant number of foreign members, such as diplomats accredited to the Court of St James's. Of the current membership of around 2,700, some 500 are "overseas members", and over 400 are women.
