Constitution Hill, London

Buckingham Palace Garden is a large private park attached to the London residence of the monarch. It is situated to the rear (west) of Buckingham Palace, occupying a 17 hectares (42 acres) site in the City of Westminster and forms the largest private garden in the capital. It is bounded by Constitution Hill to the north, Hyde Park Corner to the west, Grosvenor Place to the south-west, and the Royal Mews, Queen's Gallery, and Buckingham Palace itself to the south and east. The royal connection to the site of the garden dates from 1609 when James I purchased four acres of land "near to his palace of Westminster for the planting of mulberry trees". The garden covers much of the area of the former Goring Great Garden, named after Lord Goring, occupant of one of the earliest grand houses on the site. In 1664 Goring's mansion, and the lease on the grounds, was bought by Henry Bennet, 1st Earl of Arlington. In 1674 the house was destroyed by fire and Arlington built a replacement, named Arlington House, on the site. This house was sold by Arlington's daughter to John Sheffield, Earl of Mulgrave. Created Duke of Buckingham and Normanby in 1703, Buckingham commissioned a new mansion for the site, named Buckingham House. His architect was William Talman and his builder William Winde. Similar attention was paid to the landscape, where Buckingham engaged Henry Wise to lay out an elaborate garden in the French style, with parterres and a central canal. In the late 18th century, Buckingham House was acquired by George III whose heir, George IV used John Nash to remodel the house which was renamed Buckingham Palace. Nash engaged William Townsend Aiton to implement designs for a new garden. Aiton's work forms the basis of the garden that exists today. Buckingham Palace Garden is the setting for the Queen's annual garden parties. In June 2002 she invited the public into the garden for entertainment for the first time during her reign. As part of her Golden Jubilee Weekend thousands of Britons were invited to apply for tickets to Party at the Palace where the guitarist Brian May of the band Queen performed his God Save the Queen guitar solo on top of Buckingham Palace. This concert was preceded the previous evening by a Prom at the Palace. During the Queen's 80th birthday celebrations in 2006 the garden was the scene of Children's Party at the Palace. The garden is Grade II* listed on the Register of Historic Parks and Gardens. The planting is varied and exotic, with a mulberry tree dating back to the time of James I. Notable features include a large 19th-century lake which was once graced by a flock of flamingoes, and the Waterloo Vase. There is also a summerhouse attributed to William Kent, a helicopter landing pad on the great lawn below the West Terrace, and a tennis court. Unlike the nearby Royal Parks of London, Buckingham Palace Garden is not usually open to the public. However, when the palace is open during August and September, visitors have access to part of the garden, which forms the exit, via a gift shop in a marquee, at the end of the tour.

The Waterloo Vase is a 15-foot (4.6 m) stone urn, situated in the garden of Buckingham Palace in central London. Fashioned from a single piece of Carrara marble, it was initially presented to Napoleon I, who intended to have it carved in celebration of anticipated future military victories. After the Emperor’s defeat at the Battle of Waterloo, the uncarved vase was given to the Prince Regent, later George IV. The Prince commissioned the sculptor, Richard Westmacott to decorate the vase with reliefs celebrating the victory at Waterloo. The original plan to place the vase in the Waterloo Gallery at Windsor Castle proved unrealisable, the weight of the vase being greater than the gallery’s floors could bear. It was therefore given to the National Gallery in Trafalgar Square. Since the vase was judged surplus to requirements, the gallery moved it first to Hyde Park, London and then into storage at the Victoria and Albert Museum. In 1903, it was offered by the museum to the new king, Edward VII, who installed it as a garden ornament in the grounds of Buckingham Palace, where it remains. The vase is a Grade I listed structure.

Down Street, also known as Down Street (Mayfair), is a disused station on the London Underground, located in Mayfair, west London. The Great Northern, Piccadilly and Brompton Railway opened it in 1907. It was latterly served by the Piccadilly line and was situated between Dover Street (now named Green Park) and Hyde Park Corner stations. The station was little used; many trains passed through without stopping. Lack of patronage and proximity to other stations led to its closure in 1932. During the Second World War it was used as a bunker by the Prime Minister, Winston Churchill, and the war cabinet. The station building survives and is close to Down Street's junction with Piccadilly. Part of it is now converted to a retail outlet. London Transport Museum has been running guided tours of the station through its "Hidden London" programme since 2016. The tour covers the history of the site using archives from the museum's collection, with a focus on its Second World War connection.

The Junior Athenaeum Club was a gentlemen's club in Piccadilly, London, from 1864 to the 1930s, with similar aims to the Athenaeum Club.

The Sheraton Grand London Park Lane is a 5 Star hotel on Piccadilly, London. The hotel opened in 1927 as The Park Lane Hotel to designs by architects Adie, Button and Partners, in a grand Art Deco style, and was constructed by the developer Sir Bracewell Smith. The original architect had been C. W. Stephens, who designed Harrods, but work had stopped at the outbreak of the First World War, and Stephens died in 1917. The building is a fine example with a mansard roof and Portland stone facade. The building is Grade II listed and has 303 bedrooms on eight floors with the front overlooking Green Park towards Buckingham Palace. The hotel was bought by ITT Sheraton in April 1996 for $70 million. ITT Sheraton was acquired by Starwood in 1998. Starwood sold its leasehold on the hotel to Sir Richard Sutton's Settled Estates in 2014, but continues to operate the property, under a long-term management contract. Though the hotel was a Sheraton property from 1996 on, it did not actually begin using the Sheraton name for twenty years, until 19 July 2016, when it was renamed Sheraton Grand London Park Lane upon the completion of a major renovation.The hotel is featured in the films The End of the Affair, The Winds of War and The Golden Compass.

The Cavalry and Guards Club is a London gentlemen's club, at 127 Piccadilly, situated next to the RAF Club.

The Cavalry Club was a London gentlemen's club, which was established in 1890. In 1975, it merged with the Guards' Club, and became the Cavalry and Guards Club, which still exists today. When the Cavalry Club first occupied the site, on Piccadilly in Mayfair, in 1890, it was a proprietary club owned by an officer in the 20th Hussars, but five years later, ownership passed into the hands of its members and it became a members' club. They raised the funds to build an entirely new clubhouse, which was designed by B. N. H. Orphoot of Mewes and Davies and completed on the site in 1908.Like many London clubs, both the Cavalry Club and the Guards' Club went through a period of serious financial hardship in the 1970s. The solution proposed was a merger. The Guards' Club was due to close anyway, so their premises closed in 1975, and their 800 members joined the renamed Cavalry Club, also bringing numerous objets d'art with them.

The St James's Club was a London gentlemen's club which operated between 1857 and 1978. It was founded by two leading diplomats and its members continued to be largely diplomats and authors. It was first established in Charles Street and moved to 106 Piccadilly by 1868. In the final quarter of the twentieth century many gentlemen’s clubs of London suffered from declining membership, and in 1978 the St James's Club merged with Brooks's Club and vacated its premises.
