United Kingdom

The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign state in the European Union. Lying off the north-western coast of the European mainland, it includes the island of "Great Britain" (a term also applied loosely to refer to the whole country), 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 state—the Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-southwest. The Irish Sea lies between Great Britain and Ireland. With an area of 93,800 square miles (243,000 km²), the UK is the 80th-largest sovereign state in the world and the 11th-largest in Europe. It is also is the 21st-most populous country, with an estimated 64.5 million inhabitants.

The United Kingdom is a constitutional monarchy with a parliamentary system of governance. Its capital city is London, an important global city and financial centre with an urban population of 10,310,000, the fourth-largest in Europe and second-largest in the European Union. The current monarch—since 6 February 1952—is Queen Elizabeth II. The UK consists of four countries: England, Scotland, Wales, and Northern Ireland. The latter three have devolved administrations, each with varying powers, based in their capitals, Edinburgh, Cardiff, and Belfast, respectively. The nearby Isle of Man, Bailiwick of Guernsey and Bailiwick of Jersey are not part of the United Kingdom, being Crown dependencies with the British Government responsible for defence and international representation.

London

London ⁱ/ˈlʌndən/ is the capital and most populous city of England and the United Kingdom. Standing on the River Thames, London has been a major settlement for two millennia. It was founded by the Romans, who named it Londinium. London's ancient core, the City of London, largely retains its 1.12-square-mile (2.9 km²) medieval boundaries and in 2011 had a resident population of 7,375, making it the smallest city in England. Since at least the 19th century, the term London has also referred to the metropolis developed around this core. The bulk of this conurbation forms Greater London, a region of England governed by the Mayor of London and the London Assembly. The conurbation also covers two English counties: the small district of the City of London and the county of Greater London. The latter constitutes the vast majority of London, though historically it was split between Middlesex (a now abolished county), Essex, Surrey, Kent and Hertfordshire.

London Eye

The London Eye is a giant Ferris wheel on the South Bank of the River Thames in London. Also known as the Millennium Wheel, it has also been called by its owners the British Airways London Eye, then the Merlin Entertainments London Eye, then the EDF Energy London Eye. Since mid-January 2015, it has been known as the Coca-Cola London Eye, following an agreement signed in September 2014.

The structure is 443 feet (135 m) tall and the wheel has a diameter of 394 feet (120 m). When erected in 1999 it was the world's tallest Ferris wheel. Its height was surpassed by the 520 feet (158 m) tall Star of Nanchang in 2006, the 541 feet (165 m) tall Singapore Flyer in 2008, and the 550 feet (168 m) High Roller (Las Vegas) in 2014. Supported by an A-frame on one side only, unlike the taller Nanchang and Singapore wheels, the Eye is described by its operators as "the world's tallest cantilevered observation wheel".

It is Europe's tallest Ferris wheel, and offered the highest public viewing point in London until it was superseded by the 804 feet (245 m) observation deck on the 72nd floor of The Shard, which opened to the public on 1 February 2013. It is the most popular paid tourist attraction in the United Kingdom with over 3.75 million visitors annually, and has made many appearances in popular culture.

Buckingham Palace (UK /ˈbʌkɪŋəm/ /ˈpælɪs/) is the London residence and principal workplace of the reigning monarch of the United Kingdom. Located in the City of Westminster, the palace is often at the centre of state occasions and royal hospitality. It has been a focus for the British people at times of national rejoicing.

Originally known as Buckingham House, the building at the core of today's palace was a large townhouse built for the Duke of Buckingham in 1703 on a site that had been in private ownership for at least 150 years. It was acquired by King George III in 1761 as a private residence for Queen Charlotte and became known as "The Queen's House". During the 19th century it was enlarged, principally by architects John Nash and Edward Blore, who constructed three wings around a central courtyard. Buckingham Palace became the official royal palace of the British monarch on the accession of Queen Victoria in 1837.

Great Britain

Great Britain, also known as Britain ⁱ/ˈbrɪ.tən/, is an island in the North Atlantic off the north-west coast of continental Europe. With an area of 209,331 km² (80,823 sq mi), it is the largest island in Europe and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the third-most populous island in the world, after Java in Indonesia and Honshu in Japan. It accounts for the majority of the British Isles archipelago, along with over 1,000 smaller surrounding islands, including the island of Ireland to its west.

The island is part of the United Kingdom of Great Britain and Northern Ireland, constituting most of its territory: most of England, Scotland, and Wales are on the island, with their respective capital cities, London, Edinburgh, and Cardiff. Politically, the term Great Britain usually extends to include surrounding islands that form part of England, Scotland, and Wales.

A single Kingdom of Great Britain resulted from the Union of Scotland and England (which already comprised the present-day countries of England and Wales) in 1707. More than a hundred years before, in 1603, King James VI, King of Scots, had inherited the throne of England, but it was not until 1707 that the Parliaments of the two countries agreed to form a unified state. Subsequently, in 1801, Great Britain united with the neighbouring Kingdom of Ireland, forming the United Kingdom of Great Britain and Ireland. The state was renamed the "United Kingdom of Great Britain and Northern Ireland" after five-sixths of Ireland seceded from the United Kingdom in 1922.
