The Mall, London in the context of "Trooping the Colour"

Charing Cross (/ˈtʃærɪŋ/ CHARR-ing) is a junction in Westminster, London, England, where six routes meet. Since the early 19th century, Charing Cross has been the notional "centre of London" and became the point from which distances from London are measured. Clockwise from north, the routes that meet at Charing Cross are: the east side of Trafalgar Square leading to St Martin's Place and then Charing Cross Road; the Strand leading to the City; Northumberland Avenue leading to the Thames Embankment; Whitehall leading to Parliament Square; The Mall leading to Admiralty Arch and Buckingham Palace; and two short roads leading to Pall Mall and St James's.

Historically, the name was derived from the hamlet of Charing ('Riverbend') that occupied the area of this important road junction in the middle ages, together with the grand Eleanor cross that once marked the site. The medieval monumental cross, the Charing Cross (1294–1647), was the largest and most ornate instance of a chain of medieval Eleanor crosses running from Lincoln to this location. It was a landmark for many centuries of the hamlet of Charing, Westminster, which later gave way to government property; a little of the Strand; and Trafalgar Square. The cross in its historical forms has lent its name to its locality, including Charing Cross Station. On the forecourt of this terminus station stands the ornate Queen Eleanor Memorial Cross, a taller emulation of the original, built to mark the station's opening in 1864.

Carlton House Terrace is a street in the St James's district of the City of Westminster in London. Its principal architectural feature is a pair of terraces, the Western and Eastern terraces, of white stucco-faced houses on the south side of the street, which overlook The Mall and St. James's Park. These terraces were built on Crown land between 1827 and 1832 to overall designs by John Nash, but with detailed input by other architects including Decimus Burton. Construction was overseen by James Pennethorne. Both terrace blocks are Grade I listed buildings. A separate but linked cul-de-sac at the terrace's western end is named Carlton Gardens and has a few additional townhomes.

In the early 18th century, an aristocratic townhouse built on the site was rented by Baron Carleton, from whom the present name of the terrace derives. A century later, Carlton House, also known as Carlton Palace, gained a prominent social profile when it was enlarged and occupied by the Prince Regent. After falling out of favour with George IV, who moved into Buckingham Palace on his accession in 1820, the house was pulled down and the Crown replaced the demolished palace with the current terraces. They are divided by the Duke of York's Steps which lead down from Pall Mall to The Mall, as part of Nash's triumphal redesign of central London. A smaller flight of steps at the terrace's western end divides it from Carlton Gardens. These steps are the site of the King George VI and Queen Elizabeth Memorial.

Horse Guards Road (or just Horse Guards) is a road in the City of Westminster. Located in post code SW1A 2HQ, it runs south from The Mall down to Birdcage Walk and Great George Street, roughly parallel with Whitehall and Parliament Street.

To the west of the road is St James's Park. To the east, between Horse Guards Road and Whitehall, are various government buildings, including the five interconnected Admiralty buildings. The Old Admiralty (Ripley) Building, the oldest of the government offices, was completed in 1726. The Horse Guards building, completed in 1759, originally housed barracks and government offices. Adjacent to the Horse Guards building is a large courtyard, Horse Guards Parade, where the annual Trooping the Colour ceremony is held in the presence of the reigning monarch.

St James's Park is a 23-hectare (57-acre) urban park in the City of Westminster, central London. A Royal Park, it is at the southernmost end of the St James's area, which was named after a once isolated medieval hospital dedicated to St James the Less, now the site of St James's Palace. The area was initially enclosed for a deer park near the Palace of Whitehall for King Henry VIII in the 1530s. It is the most easterly of a near-continuous chain of public parks that includes (moving westward) Green Park, Hyde Park, and Kensington Gardens.

The park is bounded by Buckingham Palace to the west, The Mall to the north, Horse Guards to the east, and Birdcage Walk to the south. It meets Green Park at Queen's Gardens with the Victoria Memorial at its centre, opposite the entrance to Buckingham Palace. St James's Palace is on the opposite side of The Mall. The closest London Underground stations are St James's Park, Green Park, Victoria, and Westminster.

Lancaster House (originally known as York House and then Stafford House) is a mansion on The Mall in the St James's district in the City of Westminster. Adjacent to Green Park, it is next to Clarence House and St James's Palace, as much of the site was once part of the palace grounds.

Initially planned for Prince Frederick, Duke of York and Albany, it was ultimately completed by the Duke of Sutherland, then Marquess of Stafford, as an aristocratic townhouse in the early 19th century, and known for its lavish interiors. Gifted to the government in the early 20th century, it houses the government's wine cellars and was home to the London Museum until the Second World War. Now used for diplomatic receptions and related functions by the Foreign Office, it is a historic Grade I listed building, and its interiors are sometimes used in films or television as a stand-in for Buckingham Palace.

The Admiralty Arch is a historic landmark building in London, providing road and pedestrian access between The Mall, which extends to the southwest, and Trafalgar Square to the northeast. Commissioned by King Edward VII in memory of his mother, Queen Victoria, it was designed by Aston Webb, and is now a Grade I listed building. Until 2011, the building housed government offices, including the residence of the First Sea Lord, and was used by the Admiralty. In 2012, the government sold the building on a 125-year lease for £60m for redevelopment into the Waldorf Astoria London Admiralty Arch luxury hotel, which is scheduled to open in 2026.

The King George VI and Queen Elizabeth Memorial, situated between The Mall and Carlton Gardens in central London, is a memorial to King George VI and his consort, Queen Elizabeth (later the Queen Mother). Completed in its present form in 2009, the memorial incorporates an earlier, Grade II listed statue of George VI by William McMillan, unveiled by his daughter Queen Elizabeth II in 1955. The reconfigured memorial, which includes a statue of the Queen Mother by Philip Jackson, relief sculpture by Paul Day and an architectural setting by Donald Buttress and Donald Insall, was unveiled by Queen Elizabeth II in 2009.

The London Marathon (also known as the TCS London Marathon for sponsorship reasons) is an annual marathon held in London, England. Founded by athletes Chris Brasher and John Disley in 1981, it is typically held in April, although it moved to October for 2020, 2021, and 2022 due to the COVID-19 pandemic. The largely flat course is set around the River Thames, starting in Blackheath and finishing at The Mall. Hugh Brasher (son of Chris) is the current race director and Nick Bitel its chief executive.

The race has several components: it has a mass race for the public, professional races for men and women long-distance runners, elite-level wheelchair races for men and women, and a 3-mile mini marathon event for under-17 athletes. There is a significant charity running aspect to the marathon, with participants helping to raise over £1 billion since its founding, including £67 million at the 2024 London Marathon which was the highest amount for a single-day fund-raising event.
