Albemarle Gallery

Marlborough Fine Art was founded in London in 1946 by Frank Lloyd and Harry Fischer. In 1963, a gallery was opened as Marlborough-Gerson in Manhattan, New York, at the Fuller Building on Madison Avenue and 57th Street, which later relocated in 1971 to its present location, 40 West 57th Street. The gallery operates another New York space on West 25th Street, which opened in 2007. It briefly opened a Lower East Side space on Broome Street.

Thomas Agnew & Sons is a fine arts dealer in London that began life as part of in a print and publishing partnership with Vittore Zanetti in Manchester in 1817 which ended in 1835, when Agnew took full control of the company. The firm opened its London gallery in 1860, where it soon established itself as one of Mayfair's leading dealerships. Since then Agnew's has held a pre-eminent position in the world of Old Master paintings. It also had a major role in the massive growth of a market for contemporary British art in the late 19th century. In 2013, after nearly two centuries of family ownership, Agnew's closed. The name was subsequently purchased privately and the gallery is now run by Lord Anthony Crichton-Stuart, a former head of Christie's Old Master paintings department, New York.

Mahiki is a London nightclub and bar in Dover Street, just off Piccadilly, near the Ritz Hotel, well known for its celebrity clientele. It is named after the Polynesian path to the underworld. Mahiki was opened in October 2006 by Piers Adam and Nick House. The club has attracted media attention as a favourite haunt of royals including Princes William and Harry and celebrities such as Rihanna, Lady Gaga, Kelly Rowland, and Paris Hilton. Its themed Thursday nights, hosted by Henry Conway, a socialite, were particularly popular, and rival club owner Charlie Gilkes has said "Thursday nights at Mahiki ... are the night in London, there are queues going round the block."

The Wolseley is a restaurant located at 160 Piccadilly in London, England, next to the Ritz Hotel. Designed by the architect William Curtis Green, the Grade II* listed building was erected by Wolseley Motors in 1921 as their regional offices with a ground floor showroom. The ground floor was occupied by a branch of Barclays Bank between 1927 and 1999. It was a Chinese restaurant for a couple of years then reopened in 2003 as an upscale European restaurant after renovation by British restaurateurs Chris Corbin and Jeremy King.

The Stafford Gallery was an early 20th-century art gallery in London. Artists whose works were exhibited there include both internationally known painters such as Pablo Picasso, Paul Gauguin, Paul Cézanne and Gustave Courbet and significant English figures such as Walter Sickert and Sir William Nicholson. The gallery opened in the early years of the century at 34 Old Bond Street, London W., on the corner with Stafford Street; but by 1910 had moved to 1 Duke Street, St. James's.

Clarendon House was a town mansion which stood on Piccadilly in London, England, from the 1660s to the 1680s. It was built for the powerful politician Edward Hyde, 1st Earl of Clarendon, and was the grandest private London residence of its era.

50 St James's Street is a Grade II listed house in St James's Street, St James's, London SW1, opposite White's Club. It was built in 1827, and designed by the architects Benjamin Wyatt and Philip Wyatt, as Crockford's, a gentleman's club. It was altered from 1870–75 by C. J. Phipps.From 1999 to 2009, a luxury casino named Fifty, owned by Robert Earl, operated on the premises.Next, the property was secured by Luca Del Bono, an Anglo-Italian property developer. To this end, in 2011, Westminster City Council approved plans to create a members' club, spa, 14-bedroom hotel, and two public restaurants.In 2014, the property was bought by the Russian billionaire Andrey Goncharenko for £70 million, apparently with the intention of converting it to residential use. The building sat empty, until it was occupied by squatters in 2017.

Crockford's, the popular name for William Crockford's St James's Club was a London gentlemen's club, now dissolved. It was established in 1823, closed in 1845, re-founded in 1928 and closed in 1970. One of London's older clubs, it was centred on gambling and maintained a somewhat raffish and raucous reputation. It was founded by William Crockford who employed Benjamin Wyatt and Philip Wyatt to construct the city's most opulent palace of gentlemanly pleasure, which opened in November 1827. and he employed two of London's finest chefs of the time, Louis Eustache Ude and then Charles Elmé Francatelli to feed its members, food and drink being supplied free after midnight.From 1823, the club leased 50 St. James's Street, and then nos. 51–53, which enabled Crockford to pull down all four houses and build his palatial club on the site. After the club's closure, this continued to be used as a clubhouse, at first briefly by the short-lived Military, Naval and County Service Club, and then between 1874 and 1976 it was home to the Devonshire Club. The current Crockfords, though using much of the "Crocky" imagery and high-end reputation, has no connection with the original club and operates from an entirely different building at nearby 30 Curzon Street.

The Devonshire Club was a London gentlemen's club which was established in 1874 and was disbanded in 1976. Throughout its existence it was based at 50 St James's Street. The major Liberal club of the day was the Reform Club, but in the wake of the 1868 Reform Act's extension of the franchise, the waiting list for membership from the larger electorate grew to such an extent that a new club was formed to accommodate these new Liberal voters. The clubhouse was on the western side of St James's Street. The original intention was to call it the 'Junior Reform Club', along the model of the Junior Carlton Club formed in 1866, but complaints from the Reform Club's members led it to being named the Devonshire, in honour of its first chairman, the Duke of Devonshire, an aristocrat from a long line of Liberals. The club was fortunate in obtaining the St James's Street premises of Crockford's Club, a renowned eighteenth century club which had closed down in 1845. The Devonshire did well in its first decade, but found itself in an awkward position from the 1880s upon the establishment of the National Liberal Club. With a further extension of the franchise in 1885, the much larger National Liberal was aimed at these new electors, and the Devonshire came to possess neither the prestige of Brooks's or the Reform, nor the broader appeal of the National Liberal. The Devonshire soon lost its political flavour. In the 1960s the Golfers Club shared the premises using a club room at the back of the building and there was also a Masonic temple on site, catering for those lodges without premises. After a great deal of financial trouble in the 1970s (mirrored in many other clubs of the time, including the Reform, the Carlton, the St James's, the United University, the Junior Carlton, the Army and Navy, and the United Service Club), it finally closed in 1976, with its membership being absorbed by the East India Club.

The Jubilee Line Extension (JLE) is the extension of the London Underground Jubilee line from Green Park to Stratford through south and east London. An eastward extension of the line was first proposed in the 1970s. As part of the development of London Docklands, the line was extended to serve Canary Wharf and other areas of south and east London. Construction began in 1993, and it opened in stages from May to December 1999.

The Representative of Bermuda in London is the diplomatic mission of the British Overseas Territory of Bermuda in the United Kingdom. It is located in a multi-use office building in St James's. Unlike most diplomatic missions there is no flag or plaque indicating its existence, only a small label on the door-buzzer.

The Bath Hotel was located at 155 Piccadilly on the site of what is now The Ritz Hotel, London and was adjacent to the Walsingham House. The Ritz' financial backers began negotiations in 1901 and purchased the Bath in 1902 simultaneously with the acquisition of the Walsingham. One of the considerations that made the transaction appealing to the city was that they would be able to widen Piccadilly when the Walsingham and Bath Hotels were demolished.
