Westminster is an area of Central London, within the City of Westminster, England. It lies on the north bank of the River Thames, southwest of the City of London and 0.5 miles (0.8 km) southwest of Charing Cross. It has a large concentration of London's historic and prestigious landmarks and visitor attractions, including Buckingham Palace and Westminster Abbey.

Historically a part of Middlesex, the name Westminster was the ancient description for the area around Westminster Abbey – the West Minster, or monastery church, that gave the area its name – which has been the seat of the government of England (and later the British government) for almost a thousand years. Westminster is the location of the Palace of Westminster, a UNESCO World Heritage Site which houses the Parliament of the United Kingdom.

The Palace of Westminster, also known as the Houses of Parliament or Westminster Palace, is the seat 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; it has retained the style and status of a royal residence, despite its actual use.

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 and Chapter House of St Stephen's, the Chapel of St Mary Undercroft and the Jewel Tower.

The subsequent competition for the reconstruction of the Palace was won by architect Charles Barry and his design for a building in the Perpendicular Gothic style. The remains of the Old Palace (with the exception of the detached Jewel Tower) were incorporated in its much larger replacement, which contains over 1,100 rooms organised symmetrically around two series of courtyards. Part of the New Palace's area of 3.24 hectares (8 acres) was reclaimed from the Thames, which is the setting of its principal façade, the 265.8-metre (872 ft) river front. Barry was assisted by Augustus W. N. Pugin, a leading authority on Gothic architecture and style, who provided designs for the decoration and furnishings of the Palace. Construction started in 1840 and lasted for thirty years, suffering great delays and cost overruns, as well as the death of both leading architects; works for the interior decoration continued intermittently well into the twentieth century. Major conservation work has been carried out since, due to the effects of London's pollution, and extensive repairs took place after the Second World War, including the reconstruction of the Commons Chamber following its bombing in 1941.

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 northwestern coast of continental Europe. It is an island country, spanning an archipelago including Great Britain, the northeastern part of Ireland, and many small islands. Northern Ireland is the only part of the UK with a land border, sharing it with 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 largest island, Great Britain, is linked to France by the Channel Tunnel.

The United Kingdom is a constitutional monarchy and unitary state consisting of four countries: England, Northern Ireland, Scotland and Wales. It is governed by a parliamentary system with its seat of government in London, the capital, but with three devolved national administrations in Belfast, Cardiff and Edinburgh, the capitals of Northern Ireland, Wales and Scotland respectively. The Channel Island bailiwicks of Jersey and Guernsey, and the Isle of Man are Crown Dependencies, which means they are constitutionally tied to the British monarch but are not part of the UK. The UK has fourteen overseas territories, all remnants of the British Empire, which at its height in 1922 encompassed almost a quarter of the world's land surface, the largest empire in history. British influence can still be observed in the language, culture and legal systems of many of its former colonies.

This is a specific list of the UNESCO World Heritage Sites in Europe. Cyprus, Israel, Turkey, Georgia, Azerbaijan, Armenia and the Caucasian and Siberian parts of Russia are included both in this list and in the list of sites in Asia. Overseas sites of France, the Netherlands, UK and Denmark are included here, but are also repeated in the geographically relevant lists. Kazakhstan, despite having a small portion lying in Europe is to be found under Asia, where both its world heritage sites are listed. Israeli sites are listed here, since the alternative "Arab States" grouping is politically unacceptable.

Sites marked with an asterisk (*) are also included on the List of World Heritage Sites in danger.

Europe (/ˈjʊɹəp/, -əp) is, by convention, one of the world's seven continents. Comprising the westernmost peninsula of Eurasia, Europe is generally divided from Asia to its east by the water divide of the Ural Mountains, the Ural River, the Caspian Sea, the Caucasus Mountains (or the Kuma-Manych Depression), and the Black Sea to the southeast. Europe is bordered by the Arctic Ocean and other bodies of water to the north, the Atlantic Ocean to the west, the Mediterranean Sea to the south, and the Black Sea and connected waterways to the southeast. Yet the borders for Europe—a concept dating back to classical antiquity—are somewhat arbitrary, as the term continent can refer to a cultural and political distinction or a physiographic one.

Europe is the world's second-smallest continent by surface area, covering about 10,180,000 square kilometres (3,930,000 sq mi) or 2% of the Earth's surface and about 6.8% of its land area. Of Europe's approximately 50 states, Russia is the largest by both area and population, while Vatican City is the smallest. Europe is the third-most populous continent after Asia and Africa, with a population of 731 million or about 11% of the world's population. However, according to the United Nations (medium estimate), Europe's share may fall to about 7% by 2050. In 1900, Europe's share of the world's population was 25%.
