Houses of Parliament

The Palace of Westminster, also known as the Houses of Parliament or Westminster Palace, is the meeting place of the two houses of the Parliament of the United Kingdom—the House of Lords and the House of Commons. It lies on the north bank of the River Thames in the heart of the London borough of the City of Westminster, close to the historic Westminster Abbey and the government buildings of Whitehall and Downing Street. The name may refer to either of two structures: the Old Palace, a medieval building complex, most of which was destroyed in 1834, and its replacement New Palace that stands today. The palace retains its original style and status as a royal residence for ceremonial purposes.

The first royal palace was built on the site in the eleventh century, and Westminster was the primary London residence of the Kings of England until a fire destroyed much of the complex in 1512. After that, it served as the home of Parliament, which had been meeting there since the thirteenth century, and the seat of the Royal Courts of Justice, based in and around Westminster Hall. In 1834, an even greater fire ravaged the heavily rebuilt Houses of Parliament, and the only structures of significance to survive were Westminster Hall, the Cloisters of St Stephen's, the Chapel of St Mary Undercroft and the Jewel Tower.

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.

A capital city (or just, capital) is the area of a country, province, region, or state considered to enjoy primary status; although there are exceptions, a capital is typically a city that physically encompasses the offices and meeting places of the seat of government and is usually fixed by law or by the constitution. An alternative term is political capital, but this phrase has a second meaning based on an alternate sense of the word capital. The capital is often, but not necessarily, the largest city of its constituent area, and is also often a specialized city.

The word capital derives from the Latin caput meaning "head" and, in the United States, the related term capitol refers to the building where Congress meets.

The seats of government in major sub-state jurisdictions are often called "capitals," but this is typically only the case in countries with some degree of federalism, where major sub-state legal jurisdictions have elements of sovereignty. In unitary states, an "administrative centre" or other similar term is typically used for such locations besides the national capital city. For example, the seat of government in a state of the United States is usually called its "capital", but the main city in a region of the United Kingdom is usually not called such, even though in Ireland, a county's main town is usually called its "capital". On the other hand, the four main subdivisions of the United Kingdom do have capital cities: Scotland – Edinburgh, Wales – Cardiff, Northern Ireland – Belfast, and England – London. Counties in England, Wales and Scotland have historic county towns, which are often not the largest settlement within the county and often are no longer administrative centres, as many historical counties are now only ceremonial, and administrative boundaries are different.
