The Gherkin, London

London ⁱ/ˈlʌndən/ is the capital city of England and the United Kingdom, the largest metropolitan area in the United Kingdom, and the largest urban zone in the European Union by most measures. Located on the River Thames, London has been a major settlement for two millennia, its history going back to its founding by the Romans, who called it Londinium. London's ancient core, the City of London, largely retains its square-mile mediaeval boundaries. Since at least the 19th century, the name London has also referred to the metropolis developed around this core. The bulk of this conurbation forms the London region and the Greater London administrative area, governed by the elected Mayor of London and the London Assembly.

The City of London is an area in central London, England. In the medieval period it constituted most of London, but the conurbation has grown far beyond it. As the City’s boundaries have remained almost unchanged since the Middle Ages, it is now only a tiny part of the metropolis, though it remains a notable part of central London and holds city status in its own right.

It is often referred to as the City (often written on maps as "City") or the Square Mile, as it is just over one square mile (1.12 sq mi/2.90 km²) in area. These terms are also often used as metonyms for the United Kingdom's financial services industry, which continues a notable history of being based in the City.

The term London now refers to a much larger conurbation roughly corresponding to Greater London, a local government area which includes 32 London boroughs including the City of Westminster as well as the City of London. The local authority for the City, the City of London Corporation, is unique in the United Kingdom, and has some unusual responsibilities for a local authority in Britain, such as being the police authority for the City. It also has responsibilities and ownerships beyond the City's boundaries. The Corporation is headed by the Lord Mayor of the City of London, an office separate from (and much older than) the Mayor of London.

Architecture (Latin architectura, from the Greek ἀρχιτέκτων – arkhitekton, from ἀρχι- "chief" and τέκτων "builder, carpenter, mason") is both the process and product of planning, designing and construction. Architectural works, in the material form of buildings, are often perceived as cultural symbols and as works of art. Historical civilizations are often identified with their surviving architectural achievements.

"Architecture" can mean:

In relation to buildings, architecture has to do with the planning, designing and constructing form, space and ambience that reflect functional, technical, social, environmental, and aesthetic considerations. It requires the creative manipulation and coordination of material, technology, light and shadow. Architecture also encompasses the pragmatic aspects of realizing buildings and structures, including scheduling, cost estimating and construction administration. As documentation produced by architects, typically drawings, plans and technical specifications, architecture defines the structure and/or behavior of a building or any other kind of system that is to be or has been constructed.

Modern architecture is generally characterized by simplification of form and creation of ornament from the structure and theme of the building. It is a term applied to an overarching movement, with its exact definition and scope varying widely. In a broader sense, early modern architecture began at the turn of the 20th century with efforts to reconcile the principles underlying architectural design with rapid technological advancement and the modernization of society. It would take the form of numerous movements, schools of design, and architectural styles, some in tension with one another, and often equally defying such classification.

The concept of modernism would be a central theme in these efforts. Gaining popularity after the Second World War, architectural modernism was adopted by many influential architects and architectural educators, and continues as a dominant architectural style for institutional and corporate buildings into the 21st century. Modernism eventually generated reactions, most notably Postmodernism which sought to preserve pre-modern elements, while Neomodernism emerged as a reaction to Postmodernism.

Notable architects important to the history and development of the modernist movement include Frank Lloyd Wright, Ludwig Mies van der Rohe, Walter Gropius, Le Corbusier, Oscar Niemeyer and Alvar Aalto.

Norman Robert Foster, Baron Foster of Thames Bank, OM Kt. (born 1 June 1935) is a British architect whose company maintains an international design practice, Foster + Partners.

Foster was raised in Manchester in a working-class family and was intrigued by design and engineering from a young age. His years observing Mancunian architecture subsequently influenced his works, and was inspired to pursue a career in architecture after a treasurer clerk noticed his sketches and interest in Manchester's buildings while he worked at Manchester Town Hall.

Foster gained an internship at a local architect's office before submitting a portfolio and winning a place at the University of Manchester School of Architecture. He subsequently won a scholarship to study at the Yale School of Architecture in the United States of America.

Foster returned to the United Kingdom in 1963 and set up a practice, Team 4 which became Foster + Partners. His breakthrough building was arguably the Willis Building in Ipswich in 1975 and he has since designed landmark structures such as Wembley Stadium and 30 St Mary Axe. He is one of Britain's most prolific architects of his generation. In 2009 Foster was awarded the Prince of Asturias Award in the Arts category.

The United Kingdom of Great Britain and Northern Ireland (commonly known as the United Kingdom, the UK, or Britain) is a sovereign state located off the north-western coast of continental Europe. The country includes the island of Great Britain, the north-eastern part of the island of Ireland and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign state—the Republic of Ireland. Apart from this land border the UK is surrounded by the Atlantic Ocean, the North Sea, the English Channel and the Irish Sea.

The United Kingdom is a unitary state governed under a constitutional monarchy and a parliamentary system, with its seat of government in the capital city of London. It is a country in its own right and consists of four countries: England, Northern Ireland, Scotland and Wales. There are three devolved national administrations, each with varying powers, based in Belfast, Cardiff and Edinburgh, the capitals of Northern Ireland, Wales and Scotland respectively. Associated with the UK, but not constitutionally part of it, are three Crown Dependencies. The United Kingdom has fourteen overseas territories. These are remnants of the British Empire which, at its height in 1922, encompassed almost a quarter of the world's land surface and was the largest empire in history. British influence can still be observed in the language, culture and legal systems of many of its former territories.
