Diana, Princess of Wales Memorial Fountain

The Serpentine (also known as the Serpentine River) is a 40-acre (16 ha) recreational lake in Hyde Park, London, England, created in 1730 at the behest of Queen Caroline. Although it is common to refer to the entire body of water as the Serpentine, the name refers in the strict sense only to the eastern half of the lake. Serpentine Bridge, which marks the boundary between Hyde Park and Kensington Gardens, also marks the Serpentine's western boundary; the long and narrow western half of the lake is known as the Long Water. The Serpentine takes its name from its snakelike, curving shape, although it only has one bend. Originally fed by the River Westbourne and Tyburn Brook in the 1730s, the lake's water was then pumped from the Thames in the 1830s. The water is now pumped from three boreholes within Hyde Park, the most recent being installed in May 2012 as part of the 2011–2012 restoration of the lake. The Serpentine provided a focal point for The Great Exhibition of 1851, and more recently was a venue for the men's and women's triathlon and marathon swimming events in the London 2012 Olympics. Since 1864, the Serpentine Swimming Club has organised a 100-yard race every Christmas morning. In 1913, the Peter Pan Cup was inaugurated for this race by J. M. Barrie, the creator of the fictional character Peter Pan. There are many recreational facilities around the Serpentine, as well as boating on the lake itself. In 1860, the Serpentine was to be modified into a skating pond with formal edges. This scheme was not implemented. Among the landmarks near the lake is the Diana, Princess of Wales Memorial Fountain.

The Great Exhibition of the Works of Industry of All Nations, also known as the Great Exhibition or the Crystal Palace Exhibition (in reference to the temporary structure in which it was held), was an international exhibition which took place in Hyde Park, London, from 1 May to 15 October, 1851. It was the first in a series of World's Fairs, exhibitions of culture and industry that became popular in the 19th century. The event was organised by Henry Cole and Prince Albert, husband of Victoria, Queen of the United Kingdom. Famous people of the time attended the Great Exhibition, including Charles Darwin, Karl Marx, Michael Faraday (who assisted with the planning and judging of exhibits), Samuel Colt, members of the Orléanist Royal Family and the writers Charlotte Brontë, Charles Dickens, Lewis Carroll, George Eliot, Alfred Tennyson and William Makepeace Thackeray. The opening music, under the superintendence of William Sterndale Bennett, was directed by Sir George Smart. The world's first soft drink, Schweppes, was the official sponsor of the event.

Serpentine North or Serpentine North Gallery is a listed building in Hyde Park, London; which with the South Gallery constitutes the Serpentine Galleries, an art exposition space. It was originally known as The Magazine, and also, from 2013 to 2021, as the Serpentine Sackler Gallery. Since 2013, the name The Magazine names specifically an extension of the building, a restaurant designed by architect Zaha Hadid.

Kensington Road is a section of road in the Royal Borough of Kensington and Chelsea and the City of Westminster, London, forming part of the A315 road. It runs along the south edge of Kensington Gardens and Hyde Park. To the west it becomes Kensington High Street, to the east it becomes Knightsbridge, while Kensington Gore is the name applied to the middle section. To the north is Kensington Palace and to the south, the road is joined by Palace Gate, Queen's Gate, Exhibition Road, and Rutland Gate (west to east). Kensington Road houses one of the remaining thirteen Grade II listed Cabmen's Shelters used by London's taxi drivers as a place to buy food and (non-alcoholic) drink.The London bus routes 9, 23, 52, 360 and 452 serve Kensington Road. Running adjacent to Kensington Road on the south side, separated by a high wall, is Prince's Gate. It was named after a gate into Hyde Park, opened in 1848 by Edward VII, the then Prince of Wales. In 1855 some stuccoed terraces were built opposite it, facing Kensington Road. They were described by Leigh Hunt as like "a set of tall, thin gentlemen squeezing together to look at something over the way". Many of the individual properties are now embassies or offices. Notable ones include: The Embassy of Iran, 16 Prince's Gate The Embassy of Ethiopia, 17 Prince's Gate The Polish Institute and Sikorski Museum, 20 Prince's Gate The Embassy of Thailand (branch), 28 Prince's Gate The Embassy of Tunisia, 29 Prince's Gate The Embassy of the United Arab Emirates, 30 Prince's Gate The Embassy of Afghanistan, 31 Prince's Gate (entrance in Exhibition Road)Several notable people lived in Prince's Gate too. Field Marshal Douglas Haig lived and died at No. 21 in 1928; Robert Baden-Powell lived at No. 32 in 1903–14; and Joseph Chamberlain lived at No. 72 in 1880–2. No. 14 was the home of Joseph Kennedy when he was the American ambassador to Britain in 1937–40, accompanied by his son John F. Kennedy.

14 Princes Gate is the building at the east end of a terrace overlooking Hyde Park in Kensington Road, Westminster, London. The whole terrace is recorded in the National Heritage List for England as a designated Grade II listed building. The terrace is called Prince's Gate because it stands opposite the Prince of Wales' Gate to Hyde Park, named after the Prince of Wales who later became Edward VII.Built in 1849, its owners included members of the Morgan family of American bankers. Number 13 and 14 Prince's Gate were combined into an enlarged Number 14 in the early 20th century. From the 1920s to the 1950s it was the official residence of eight American ambassadors. It later became the first headquarters of the Independent Television Authority and was until 2010 the headquarters of the Royal College of General Practitioners.

The Iranian Embassy siege took place from 30 April to 5 May 1980, after a group of six armed men stormed the Iranian embassy on Prince's Gate in South Kensington, London. The gunmen, Iranian Arabs campaigning for sovereignty of Khuzestan Province, took 26 people hostage, including embassy staff, several visitors, and a police officer who had been guarding the embassy. They demanded the release of prisoners in Khuzestan and their own safe passage out of the United Kingdom. The British government quickly decided that safe passage would not be granted and a siege ensued. Subsequently, police negotiators secured the release of five hostages in exchange for minor concessions, such as the broadcasting of the hostage-takers' demands on British television. By the sixth day of the siege the gunmen were increasingly frustrated at the lack of progress in meeting their demands. That evening, they killed a hostage and threw his body out of the embassy. The Special Air Service (SAS), a special forces regiment of the British Army, initiated "Operation Nimrod" to rescue the remaining hostages, abseiling from the roof and forcing entry through the windows. During the 17-minute raid they rescued all but one of the remaining hostages and killed five of the six hostage-takers. An inquest cleared the SAS of any wrongdoing. The sole remaining gunman served 27 years in British prisons. The Iran–Iraq War broke out later that year and the hostage crisis in Tehran continued until January 1981. Nonetheless, the operation brought the SAS to the public eye for the first time and bolstered the reputation of Thatcher's government. The SAS was quickly overwhelmed by the number of applications it received from people inspired by the operation and experienced greater demand for its expertise from foreign governments. The building, damaged by fire during the assault, was not reopened until 1993. The SAS raid, televised live on a bank holiday evening, became a defining moment in British history and proved a career boost for several journalists; it became the subject of multiple documentaries and works of fiction, including several films and television series.

The Embassy of Iran in London is the diplomatic mission of Iran in the United Kingdom. It is located in a terrace overlooking Hyde Park in South Kensington, Westminster, London, next to the embassy of Ethiopia. Iran also maintains a Consular Section at 50 Kensington Court, South Kensington. The embassy building, along with the Ethiopian Embassy and the Polish Institute and Sikorski Museum, is one of a group of Grade II listed stucco buildings.The embassy was the location of the 1980 Iranian Embassy siege in which members of the Iranian-Arab nationalist group the Democratic Revolutionary Front for the Liberation of Arabistan seized the building for several days before being overrun by the SAS. The embassy was severely damaged during the siege and did not re-open until 1993.Following the 2011 attack on the British Embassy in Iran, the British government expelled all Iranian embassy staff and closed the embassy in protest, alleging government support for the attack. Between 2011 and 2014, Iranian interests in the UK were represented by the Omani Embassy. Anglo-Iranian relations have improved since the election of President Hassan Rouhani and the countries made plans to re-open the embassy.On February 20, 2014 the Embassy was restored and the two countries agreed to restart diplomatic relations.On March 9, 2018 four people from Khoddam Al-Mahdi were arrested after climbing onto the first-floor balcony of the Embassy and taking down the Iranian flag in an apparent protest against the government in Tehran due to the arrest of the Islamic scholar Hussein al-Shirazi in Qom three days earlier.

The Kingston House estate and Ennismore Gardens in Knightsbridge is a green, dual-character area within the western limits of the City of Westminster in London. The first-named is immediately south of Hyde Park, London taking up the park's semi-panorama row of 8 to 13 Princes Gate (demolished) and otherwise, as to more of its wings, set around the east of Princes Gate Garden including a terrace of houses №s 1 to 7 Bolney Gate. The second-named is a garden square of 59 tall creamy-white terraced houses and the approach road to Prince of Wales Gate, Hyde Park as well as the identical-size public, square green of the church that is since 1956 the Russian Orthodox Cathedral of the Dormition of the Mother of God and All Saints facing which green are its anomalous outlier row for a London garden square, №s 61 to 66. The relatively small, broad-fronted house set against the Consulate-used pairing at №s 61 to 62 is № 60 and as with the other 65 numbers of Ennismore Gardens is a listed building. Kingston House estate has some Art Deco features but has no statutorily listed buildings. It has four 1930s to 1950s ranges of flats in 1930s style, arranged in three parts.

The Arch 1979–1980 is a large stone sculpture by Henry Moore located in Kensington Gardens, London. It was given to the park by Moore in 1980. "After the 1978 exhibition at the Serpentine Gallery in London, in which several large pieces were located in Kensington Gardens, there was a request for me to leave a sculpture there permanently, which I agreed to do. I thought the Large Arch was very naturally sited, particularly as it could be seen reflected in the water from across the lake. During the exhibition, many people believed the sculpture to be made of marble, but in fact it was a fibreglass exhibition cast made originally for my exhibition at the Forte di Belvedere in Florence (1963), because of the difficulty of getting a very heavy bronze or marble on to the site. Therefore, so that it could be left as a permanent sculpture in Kensington Gardens, I produced a version in travertine marble which is a very lasting material."The Arch was found to be unstable in 1996, and was subsequently dismantled and placed into storage. It was restored and replaced in its original location in 2012.

Exhibit A was an art exhibition in the galleries of the Serpentine Gallery, London, from May 7—June 7, 1992.
