Trafalgar Square in the context of "Campaign for Nuclear Disarmament"

Westminster is the main settlement of the City of Westminster in Central London, England. It extends from the River Thames to Oxford Street and has many famous landmarks, including the Palace of Westminster, Buckingham Palace, Westminster Abbey, Westminster Cathedral, Trafalgar Square and much of the West End cultural centre including the entertainment precinct of West End theatre.

The name (Old English: Westmynstre) originated from the informal description of the abbey church and royal peculiar of St Peter's (Westminster Abbey), west of the City of London (until the English Reformation there was also an Eastminster abbey, on the other side of the City of London, in the East End of London). The abbey's origins date from between the 7th and 10th centuries, but it rose to national prominence when rebuilt by Edward the Confessor in the 11th century. With the development of the old palace alongside the abbey, Westminster has been the home of England's government since about 1200, and from 1707 the Government of the United Kingdom. In 1539, it became a city.

Squares have long been a feature of London and come in numerous identifiable forms. The landscaping spectrum of squares stretches from those with more hardscape, constituting town squares (also known as city squares)—to those with communal gardens, for which London is a major international exponent, known as garden squares. London's largest privately owned square is Vincent Square, in Westminster, which comprises 13 acres.

A few in the capital of the United Kingdom, such as Trafalgar Square, began as public open spaces in the same way as other city squares worldwide, typically a plaza, piazza and a platz in Spain, Italy and Germany. Most, however, began as garden squares i.e. private communal gardens for the inhabitants of surrounding houses. All types of the space are more prevalent in parts of London with high (urban) density. Some of these gardens are now open to the public, while others, for example around Notting Hill, are railed (a form of fencing) and private.

The City of Westminster is a London borough with city status in Greater London, England. It is the site of the United Kingdom's Houses of Parliament and much of the British government. It contains a large part of central London, including most of the West End, such as the major shopping areas around Oxford Street, Regent Street, Piccadilly and Bond Street, and the entertainment district of Soho. Many London landmarks are within the borough, including Buckingham Palace, Westminster Abbey, Whitehall, Westminster Cathedral, 10 Downing Street, and Trafalgar Square.

The borough also has a number of major parks and open spaces, including Hyde Park, and most of Regent's Park. Away from central London the borough also includes various inner suburbs, including St John's Wood, Maida Vale, Bayswater, Belgravia and Pimlico. The borough had a population of 204,300 at the 2021 census.

London, the capital city of England, is one of the world's most visited cities in terms of international visits, ranking third in 2024. It is home to an array of notable tourist attractions, attracting 20.3 million overnight visits in 2023, far more than any other town or city and close to the number of visits seen in 2019 (21.7 million).

The National Gallery is an art museum in Trafalgar Square in the City of Westminster, in Central London, England. Founded in 1824, it houses a collection of more than 2,300 paintings dating from the mid-13th century to 1900. The current director of the National Gallery is Gabriele Finaldi.

The National Gallery is an exempt charity, and a non-departmental public body of the Department for Culture, Media and Sport. Its collection belongs to the government on behalf of the British public, and entry to the main collection is free of charge.

Medical sociology is the sociological analysis of health, Illness, differential access to medical resources, the social organization of medicine, Health Care Delivery, the production of medical knowledge, selection of methods, the study of actions and interactions of healthcare professionals, and the social or cultural (rather than clinical or bodily) effects of medical practice. The field commonly interacts with the sociology of knowledge, science and technology studies, and social epistemology. Medical sociologists are also interested in the qualitative experiences of patients, doctors, and medical education; often working at the boundaries of public health, social work, demography and gerontology to explore phenomena at the intersection of the social and clinical sciences. Health disparities commonly relate to typical categories such as class, race, ethnicity, immigration, gender, sexuality, and age. Objective sociological research findings quickly become a normative and political issue.

Early work in medical sociology was conducted by Lawrence J Henderson whose theoretical interests in the work of Vilfredo Pareto inspired Talcott Parsons' interests in sociological systems theory. Parsons is one of the founding fathers of medical sociology, and applied social role theory to interactional relations between sick people and others. Later other sociologists such as Eliot Freidson have taken a conflict theory perspective, looking at how the medical profession secures its own interests. Key contributors to medical sociology since the 1950s include Howard S. Becker, Mike Bury, Peter Conrad, Jack Douglas, Eliot Freidson, David Silverman, Phil Strong, Bernice Pescosolido, Carl May, Anne Rogers, Anselm Strauss, Renee Fox, and Joseph W. Schneider.

St Martin's Lane is a street in the City of Westminster, which runs from the church of St Martin-in-the-Fields, after which it is named, near Trafalgar Square northwards to Long Acre. At its northern end, it becomes Monmouth Street. St Martin's Lane and Monmouth Street together form the B404.

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.

Central London is the innermost part of London, in England, spanning the City of London and several boroughs. Over time, a number of definitions have been used to define the scope of Central London for statistics, urban planning and local government. Its characteristics are understood to include a high-density built environment, high land values, an elevated daytime population and a concentration of regionally, nationally and internationally significant organisations and facilities.

Road distances to London are traditionally measured from a central point at Charing Cross (in the City of Westminster), which is marked by the statue of King Charles I at the junction of the Strand, Whitehall and Cockspur Street, just south of Trafalgar Square.
