The Guildhall

The Guildhall complex in c.1805. The buildings on the left and right have not survived.

The Guildhall is a building in the City of London, off Gresham and Basinghall streets, in the wards of Bassishaw and Cheap. It has been used as a town hall for several hundred years, and is still the ceremonial and administrative centre of the City of London and its Corporation. The term Guildhall refers both to the whole building and to its main room, which is a medieval-style great hall. The Guildhall complex houses the offices of the City of London Corporation and various public facilities.

The Guildhall should not be confused with London City Hall, which is the administrative centre for Greater London, of which the City of London is only a small part.

The nearest London Underground stations are Bank, St Paul's and Moorgate.

History[link]

Roman, Saxon and Medieval[link]

The great hall is believed to be on a site of an earlier Guildhall (one possible derivation for the word 'guildhall' is the Anglo-Saxon 'gild', meaning payment, with a "gild-hall" being where citizens would pay their taxes). During the Roman period, it was the site of an amphitheatre, the largest in Britannia, partial remains of which are on public display in the basement of the Guildhall Art Gallery and the outline of whose arena is marked with a black circle on the paving of the courtyard in front of the hall. Indeed, the siting of the Saxon Guildhall here was probably due to the amphitheatre's remains^[1] Excavations by MOLAS in 2000 at the entrance to Guildhall Yard exposed remains of the great 13th-century gatehouse built directly over the southern entrance to the Roman amphitheatre, which raises the possibility that enough of the Roman structure survived to influence the siting not only of the gatehouse and Guildhall itself but also of the church of St Lawrence Jewry whose strange alignment may shadow the elliptical form of the amphitheatre beneath.^[2] The first documentary reference to a London Guildhall is dated 1128 and the current hall's west crypt may be part of a late-13th century building. Legendary British history made the Guildhall's site the site of the palace of Brutus of Troy.

1441-present[link]

The current building was begun in c. 1411, and it is the only stone building not belonging to the Church to have survived the Great Fire of London in 1666. The complex contains several other historic interiors besides the hall, including the large mediaeval crypts, the old library, and the print room, all of which are now used as function rooms.

Trials in this hall have included those of Anne Askew (Protestant martyr), Henry Howard, Earl of Surrey, Sir Nicholas Throckmorton, Lady Jane Grey, Guildford Dudley, Thomas Cranmer, Henry Peckham, John Daniel, John Felton (Catholic), Roderigo Lopez, Henry Garnet (in connection with the Gunpowder Plot), Sir Gervase Helwys (in connection with the Overbury plot) and it contains memorials to Pitt the Elder, Pitt the Younger, Admiral Lord Nelson, the Duke of Wellington, William Beckford, and Winston Churchill. It also played a part in Jack Cade's 1450 rebellion.

The Great Hall did not completely escape damage in 1666; it was partially restored - with a flat roof - in 1670. The present grand entrance (the east wing of the south front), in "Hindoostani Gothic", was added in 1788 by George Dance (and restored in 1910). A more extensive restoration than that in 1670 was completed in 1866 by City of London architect Sir Horace Jones, who added a new timber roof in close keeping with the original. This replacement was destroyed during The Second Great Fire of London on the night of 29/30 December 1940, the result of a Luftwaffe fire-raid. It was replaced in 1954 during works designed by Sir Giles Gilbert Scott.

Present[link]

The day-to-day administration of the City of London Corporation is now conducted from modern buildings immediately to the north of the Guildhall, but the Guildhall itself and the adjacent historic interiors are still used for official functions, and it is open to the public during the annual London Open House weekend. The Guildhall Art Gallery was added to the complex in the 1990s. The Clockmakers' Museum and the Guildhall Library, a public reference library with specialist collections on London, which include material from the 11th century onwards, are also housed in the complex.

The marathon route of the 2012 Summer Olympics is planned to pass through Guildhall Yard.^[3]

Gog and Magog[link]

Two giants, Gog and Magog, are associated with the Guildhall. Legend has it that the two giants were defeated by Brutus and chained to the gates of his palace on the site of Guildhall. Carvings of Gog and Magog are kept in the Guildhall and taken out and paraded in the annual Lord Mayor's Show.

An early version of Gog and Magog were destroyed in the Guildhall during the Great Fire of London. They were replaced in 1708 by a large pair of wooden statues carved by Captain Richard Saunders. These giants, on whom the current versions are based, lasted for over two hundred years before they were destroyed in the Blitz. They, in turn, were replaced by a new pair carved by David Evans in 1953 and given to the City of London by Alderman Sir George Wilkinson, who had been Lord Mayor in 1940 at the time of the destruction of the previous versions.

Functions[link]

The Guildhall hosts many events throughout the year, the most notable one being the Lord Mayor’s Banquet, which is held in honour of the immediate-past Lord Mayor and is the first to be hosted by the new Lord Mayor of the City of London. In keeping with tradition, it is at this Banquet that the Prime Minister makes a major World Affairs speech. One of the last acts of the outgoing Lord Mayor is to present prizes at the City of London School prize day at the Guildhall. Other events include those of various law firms, award evenings for the Wine and Spirit Education Trust (WSET), and the famous banquet for the International Wine and Spirit Competition (IWSC). The Worshipful Company of Carmen holds its Cart-Marking ceremony in the courtyard each July. See www.thecarmen.co.uk

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.^{[note 1]} 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 named it Londinium.^[3] 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.^[4] The bulk of this conurbation forms the London region^[5] and the Greater London administrative area,^{[6][note 2]} governed by the elected Mayor of London and the London Assembly.^[7]

London is a leading global city, with strengths in the arts, commerce, education, entertainment, fashion, finance, healthcare, media, professional services, research and development, tourism and transport all contributing to its prominence.^[8] It is the world's leading financial centre alongside New York City^[9][10][11] and has the fifth-largest city GDP in the world (and the largest in Europe).^[12] London has been described as a world cultural capital.^{[13][14][15][16]} It was the world's most visited city during 2011 ^[17][18] and London Heathrow is the world's busiest airport by number of international passengers.^[19] London's 43 universities form the largest concentration of higher education in Europe.^[20] In 2012 London will become the first city to host the modern Summer Olympic Games three times.^[21]

London has a diverse range of peoples and cultures, and more than 300 languages are spoken within its boundaries.^[22] In July 2010 Greater London had an official population of 7,825,200, making it the most populous municipality in the European Union,^[2][23] and accounting for 12.5% of the UK population.^[24] The Greater London Urban Area is the second-largest in the EU with a population of 8,278,251,^[25] while London's metropolitan area is the largest in the EU with an estimated total population of between 12 million^[26] and 14 million.^[27] London had the largest population of any city in the world from around 1831 to 1925.^[28]

London contains four World Heritage Sites: the Tower of London; Kew Gardens; the site comprising the Palace of Westminster, Westminster Abbey, and St Margaret's Church; and the historic settlement of Greenwich (in which the Royal Observatory marks the Prime Meridian (0° longitude) and GMT).^[29] Other famous landmarks include Buckingham Palace, the London Eye, Piccadilly Circus, St Paul's Cathedral, Tower Bridge, Trafalgar Square, Wembley Stadium, and Shard London Bridge. London is home to numerous museums, galleries, libraries, sporting events and other cultural institutions, including the British Museum, Natural History Museum, National Gallery, Tate Modern, British Library, Wimbledon, and 40 West End theatres.^[30] The London Underground is the oldest underground railway network in the world^[31] and the second-most extensive (after the Shanghai Metro).^[32]

History[link]

Toponymy[link]

The name London may derive from the River Thames

The etymology of London is uncertain.^[33] It is an ancient name and can be found in sources from the 2nd century. It is recorded c. 121 as Londinium, which points to Romano-British origin.^[33] The earliest attempted explanation, now disregarded, is attributed to Geoffrey of Monmouth in Historia Regum Britanniae.^[33] This had it that the name originated from a supposed King Lud, who had allegedly taken over the city and named it Kaerlud.^[34]

From 1898 it was commonly accepted that the name was of Celtic origin and meant place belonging to a man called *Londinos; this explanation has since been rejected.^[33] Richard Coates put forward an explanation in 1998 that it is derived from the pre-Celtic Old European *(p)lowonida, meaning 'river too wide to ford', and suggested that this was a name given to the part of the River Thames which flows through London; from this, the settlement gained the Celtic form of its name, *Lowonidonjon.^[35]

Until 1889 the name "London" officially only applied to the City of London but since then it has also referred to the County of London and now Greater London.^[4]

Prehistory and antiquity[link]

In 1300 the City was still confined within the Roman walls.

Although there is evidence of scattered Brythonic settlements in the area, the first major settlement was founded by the Romans in 43 AD.^[36] This lasted for just seventeen years and around 61, the Iceni tribe led by Queen Boudica stormed it, burning it to the ground.^[37] The next, heavily planned incarnation of the city prospered and superseded Colchester as the capital of the Roman province of Britannia in 100. At its height during the 2nd century, Roman London had a population of around 60,000. By the 7th century, the Anglo-Saxons had created a new settlement called Lundenwic over a mile (2 km) upstream from the old Roman city, around what is now Covent Garden.^[38]

It is likely that there was a harbour at the mouth of the River Fleet for fishing and trading, and this trading grew, until the city was overcome by the Vikings and forced to move east, back to the location of the Roman Londinium, in order to use its walls for protection.^[39] Viking attacks continued to increase, until 886 when Alfred the Great recaptured London and made peace with the Danish leader, Guthrum.^[40] The original Saxon city of Lundenwic became Ealdwic ("old city"), a name surviving to the present day as Aldwych, which is in the modern City of Westminster.^[41]

Two recent discoveries indicate that London could be much older than previously thought. In 1999 the remains of a Bronze Age bridge were found on the foreshore north of Vauxhall Bridge.^[42] This bridge either crossed the Thames, or went to a (lost) island in the river. Dendrology dated the timbers to 1500BC.

In 2010 the foundations of a large timber structure, dated to 4500BC, were found on the Thames foreshore, South of Vauxhall Bridge.^[43] The function of the mesolithic structure is not known, but it covers at least 50m x 10m, and numerous 30 cm posts are visible at low tides. Both structures are on South Bank, at a natural crossing point where the River Effra flows into the River Thames, and 4 km upstream from the Roman City of London. The effort required to construct these structures implies trade, stability, and a community size of several hundred people at least.

Middle Ages[link]

The Lancastrian siege of London in 1471 is attacked by a Yorkist sally.

With the collapse of Roman rule in the early 5th century, London was effectively abandoned. However, from the 6th century an Anglo-Saxon settlement known as Lundenwic developed slightly to the west of the old Roman city, around what is now Covent Garden and the Strand, rising to a likely population of 10–12,000.^[38] In the 9th century London was repeatedly attacked by Vikings, leading to a relocation of the city back to the location of Roman Londinium, in order to use its walls for protection.^[39] Following the unification of England in the 10th century London, already the country's largest city and most important trading centre, became increasingly important as a political centre, although it still faced competition from Winchester, the traditional centre of the kingdom of Wessex.

In the 11th century King Edward the Confessor re-founded and rebuilt Westminster Abbey and Westminster, a short distance upstream from London became a favoured royal residence. From this point onward Westminster steadily supplanted the City of London itself as a venue for the business of national government.^[44]

Westminster Abbey is a World Heritage Site and one of London's oldest and most important buildings as seen in this painting (Canaletto, 1749 A.D.)

Following his victory in the Battle of Hastings, William, Duke of Normandy, was crowned King of England in the newly finished Westminster Abbey on Christmas Day 1066.^[45] William constructed the Tower of London, the first of the many Norman castles in England to be rebuilt in stone, in the southeastern corner of the city to intimidate the native inhabitants.^[46] In 1097, William II began the building of Westminster Hall, close by the abbey of the same name. The hall became the basis of a new Palace of Westminster.^[47][48]

During the 12th century the institutions of central government, which had hitherto accompanied the royal court as it moved around the country, grew in size and sophistication and became increasingly fixed in one place. In most cases this was Westminster, although the royal treasury, having been moved from Winchester, came to rest in the Tower. While the City of Westminster developed into a true capital in governmental terms, its distinct neighbour, the City of London, remained England's largest city and principal commercial centre and flourished under its own unique administration, the Corporation of London. In 1100 its population was around 18,000; by 1300 it had grown to nearly 100,000.^[49]

Disaster struck during the Black Death in the mid-14th century, when London lost nearly a third of its population.^[50] London was the focus of the Peasants' Revolt in 1381.^[51]

Early modern[link]

The Great Fire of London destroyed many parts of the city in 1666.

London in 1806

During the Tudor period the Reformation produced a gradual shift to Protestantism, with much of London passing from church to private ownership.^[52] The traffic in woollen cloths shipped undyed and undressed from London to the nearby shores of the Low Countries, for use by well-to-do wearers chiefly in the interior of the continent. But the tentacles of English maritime enterprise hardly extended beyond the seas of north-west Europe. The commercial route to Italy and the Mediterranean Sea normally lay through Antwerp and over the Alps; any ship passing through the Strait of Gibraltar to or from England were likely to be Italian or Ragusan. Upon the re-opening of the Netherlands to English shipping in January 1565 there at once ensued a strong outburst of commercial activity.^[53] The Royal Exchange was founded.^[54] Mercantilism grew and monopoly trading companies such as the East India Company were established, with trade expanding to the New World. London became the principal North Sea port, with migrants arriving from England and abroad. The population rose from an estimated 50,000 in 1530 to about 225,000 in 1605.^[52]

In the 16th century William Shakespeare and his contemporaries lived in London at a time of hostility to the development of the theatre. By the end of the Tudor period in 1603, London was still very compact. There was an assassination attempt on James I in Westminster, through the Gunpowder Plot on 5 November 1605.^[55] London was plagued by disease in the early 17th century,^[56] culminating in the Great Plague of 1665–1666, which killed up to 100,000 people, or a fifth of the population.^[57]

The Great Fire of London broke out in 1666 in Pudding Lane in the city and quickly swept through the wooden buildings.^[58] Rebuilding took over ten years and was supervised by Robert Hooke^[59][60][61] as Surveyor of London.^[62] In 1708 Christopher Wren's masterpiece, St Paul's Cathedral was completed. During the Georgian era new districts such as Mayfair were formed in the west; and new bridges over the Thames encouraged development in South London. In the east, the Port of London expanded downstream.

In 1762 George III acquired Buckingham House and it was enlarged over the next 75 years. During the 18th century, London was dogged by crime and the Bow Street Runners were established in 1750 as a professional police force.^[63] In total, more than 200 offences were punishable by death,^[64] and women and children were hanged for petty theft.^[65] Over 74 per cent of children born in London died before they were five.^[66] The coffeehouse became a popular place to debate ideas, with growing literacy and the development of the printing press making news widely available; and Fleet Street became the centre of the British press.

According to Samuel Johnson:

Late modern and contemporary[link]

A London street hit during the Blitz of World War II

London was the world's largest city from about 1831 to 1925.^[68] London's overcrowded conditions led to cholera epidemics,^[69] claiming 14,000 lives in 1848, and 6,000 in 1866.^[70] Rising traffic congestion led to the creation of the world's first local urban rail network. The Metropolitan Board of Works oversaw infrastructure expansion. It was replaced in 1889 by the London County Council, London's first elected city-wide administration. The Blitz and other bombing by the German Luftwaffe during World War II killed over 30,000 Londoners and destroyed large tracts of housing and other buildings across London. Immediately after the war, the 1948 Summer Olympics were held at the original Wembley Stadium, at a time when the city had barely recovered from the war.

In 1951 the Festival of Britain was held on the South Bank. The Great Smog of 1952 led to the Clean Air Act 1956, which ended the "pea-souper" fogs for which London had been notorious. From the 1940s onwards, London became home to a large number of immigrants, largely from Commonwealth countries such as Jamaica, India, Bangladesh and Pakistan, making London one of the most diverse cities in Europe.

Primarily starting in the mid-1960s, London became a centre for the worldwide youth culture, exemplified by the Swinging London subculture associated with the King's Road, Chelsea and Carnaby Street. The role of trendsetter was revived during the punk era. In 1965 London's political boundaries were expanded to take into account the growth of the urban area and a new Greater London Council was created. During The Troubles in Northern Ireland, London was subjected to bombing attacks by the Provisional IRA. Racial inequality was highlighted by the 1981 Brixton riot. Greater London's population declined steadily in the decades after World War II, from an estimated peak of 8.6 million in 1939 to around 6.8 million in the 1980s. The principal ports for London moved downstream to Felixstowe and Tilbury, with the London Docklands area becoming a focus for regeneration as the Canary Wharf development. This was borne out of London's ever-increasing role as a major international financial centre during the 1980s.

The Thames Barrier was completed in the 1980s to protect London against tidal surges from the North Sea. The Greater London Council was abolished in 1986, which left London as the only large metropolis in the world without a central administration. In 2000, London-wide government was restored, with the creation of the Greater London Authority. To celebrate the start of the 21st century, the Millennium Dome, London Eye and Millennium Bridge were constructed. On 7 July 2005, three London Underground trains and a double-decker bus were bombed in a series of terrorist attacks.^[71]

Local government[link]

The Greater London Authority is based in City Hall, Southwark

The administration of London is formed of two tiers—a city-wide, strategic tier and a local tier. City-wide administration is coordinated by the Greater London Authority (GLA), while local administration is carried out by 33 smaller authorities.^[72] The GLA consists of two elected components; the Mayor of London, who has executive powers, and the London Assembly, who scrutinise the mayor's decisions and can accept or reject his budget proposals each year. The headquarters of the GLA is City Hall, Southwark; the current mayor is Boris Johnson. The mayor's statutory planning strategy is published as the London Plan, which was most recently revised in 2011.^[73] The local authorities are the councils of the 32 London boroughs and the City of London Corporation.^[74] They are responsible for most local services, such as local planning, schools, social services, local roads and refuse collection. Certain functions, such as waste management, are provided through joint arrangements. In 2009–2010 the combined revenue expenditure by London councils and the GLA amounted to just over 22 billion ₤ (14.7 billion ₤ for the boroughs and 7.4 billion ₤ for the GLA)^[75]

Policing in Greater London, with the exception of the City of London, is provided by the Metropolitan Police Force, overseen by the Metropolitan Police Authority. The City of London has its own police force – the City of London Police.^[76] The British Transport Police are responsible for police services on National Rail and London Underground services in the capital.^[77]

The London Fire Brigade is the statutory fire and rescue service for Greater London. It is run by the London Fire and Emergency Planning Authority and is the third-largest fire service in the world.^[78] National Health Service ambulance services are provided by the London Ambulance Service (LAS) NHS Trust, the largest free at the point of use emergency ambulance service in the world.^[79] The London Air Ambulance charity operates in conjunction with the LAS where required. Her Majesty's Coastguard and the Royal National Lifeboat Institution operate on the River Thames.^[80][81]

National government[link]

London is the seat of the Government of the United Kingdom, which is located around the Palace of Westminster. Many government departments are located close to Parliament, particularly along Whitehall, including the Prime Minister's residence at 10 Downing Street.^[82] The British Parliament is often referred to as the "Mother of Parliaments" (although this sobriquet was first applied to England itself by John Bright)^[83] because it has been the model for most other parliamentary systems, and its Acts have created many other parliaments.

Geography[link]

Scope[link]

Greater London is the top-level administrative subdivision covering London. The small, ancient City of London at its core once contained the whole settlement, but as the urban area grew the City Corporation resisted attempts to amalgamate it with its suburbs, causing "London" to be defined in a number ways for different purposes; and the situation was once open to legal debate.^[84] Forty per cent of Greater London is covered by the London post town, within which 'LONDON' forms part of postal addresses.^[85][86]

Satellite view of London

Map of central London

The London telephone area code (020) covers a larger area, similar in size to Greater London, although some outer districts are omitted and some places just outside are included. The area within the orbital M25 motorway is normally what is referred to as 'London'.^[87] and the Greater London boundary has been aligned to it in places.^[88]

Outward urban expansion is now prevented by the Metropolitan Green Belt,^[89] although the built-up area extends beyond the boundary in places, resulting in a separately defined Greater London Urban Area. Beyond this is the vast London commuter belt.^[90] Greater London is split for some purposes into Inner London and Outer London.^[91] The city is split by the River Thames into North and South, with an informal central London area in its interior. The coordinates of the nominal centre of London, traditionally considered to be the original Eleanor Cross at Charing Cross near the junction of Trafalgar Square and Whitehall, are approximately 51°30′26″N 00°07′39″W / 51.50722°N 0.1275°W / 51.50722; -0.1275.^[92]

Status[link]

Within London, both the City of London and the City of Westminster have city status and both the City of London and the remainder of Greater London are the ceremonial counties.^[93] The current area of Greater London has incorporated areas that were once part of the counties of Middlesex, Kent, Surrey, Essex and Hertfordshire.^[94] London's status as the capital of England, and later the United Kingdom, has never been granted or confirmed officially—by statute or in written form.^{[note 3]}

Its position was formed through constitutional convention, making its status as de facto capital a part of the UK's unwritten constitution. The capital of England was moved to London from Winchester as the Palace of Westminster developed in the 12th and 13th centuries to become the permanent location of the royal court, and thus the political capital of the nation.^[98] More recently, Greater London has been defined as a region of England and in this context known as London.^[5]

Topography[link]

Primrose Hill

Greater London covers an area of 1,583 square kilometres (611 sq mi), an area which had a population of 7,172,036 in 2001 and a population density of 4,542 inhabitants per square kilometre (11,760 /sq mi). A larger area, referred to as the London Metropolitan Region or the London Metropolitan Agglomeration covers an area of 8,382 square kilometres (3,236 sq mi) has a population of 12,653,500 and a population density of 1,510 inhabitants per square kilometre (3,900 /sq mi).^[99] Modern London stands on the Thames, its primary geographical feature, a navigable river which crosses the city from the south-west to the east. The Thames Valley is a floodplain surrounded by gently rolling hills including Parliament Hill, Addington Hills, and Primrose Hill. The Thames was once a much broader, shallower river with extensive marshlands; at high tide, its shores reached five times their present width.^[100]

Since the Victorian era the Thames has been extensively embanked, and many of its London tributaries now flow underground. The Thames is a tidal river, and London is vulnerable to flooding.^[101] The threat has increased over time due to a slow but continuous rise in high water level by the slow 'tilting' of Britain (up in the north and down in the south) caused by post-glacial rebound.^[102]

In 1974, a decade of work began on the construction of the Thames Barrier across the Thames at Woolwich to deal with this threat. While the barrier is expected to function as designed until roughly 2070, concepts for its future enlargement or redesign are already being discussed.^[103]

Climate[link]

London has a temperate oceanic climate, similar to much of southern Britain. Despite its reputation as being a rainy city, London receives less precipitation in a year than Rome at 834 mm (32.8 in), or Bordeaux at 923 mm (36.3 in).^[104] Winters are generally chilly to cold with frost usually occurring in the suburbs on average twice a week from November to March. Snow usually occurs about 4 or 5 times a year mostly from December to February. Snowfall during March and April is rare but does occur every 2–3 years. Winter temperatures seldom fall below −4 °C (24.8 °F) or rise above 14 °C (57.2 °F). During the winter of 2010, London experienced its lowest temperature on record (−14 °C (6.8 °F)) in Northolt and the heaviest snow seen for almost two decades, a huge strain on London's transport infrastructure. Summers are generally warm and sometimes hot, the heat being boosted by the urban heat island effect making the centre of London at times 5 °C (9 °F) warmer than the suburbs and outskirts. London's summer average is 24 °C (75.2 °F). On average there are 7 days a year above 30 °C (86.0 °F) and 2 days a year above 32 °C (89.6 °F). Temperatures of 26 °C (80 °F) usually occur on a weekly basis from mid- June to late August. During the 2003 European heat wave there were 14 consecutive days above 30 °C (86.0 °F) and 2 consecutive days where temperatures soared up to 38 °C (100.4 °F), leading to hundreds of heat related deaths. Rain generally occurs on around 2 out of 10 summer days. Spring and Autumn are mixed seasons and can be pleasant. On 1 October 2011, the air temperature attained 30 °C (86.0 °F) and in April 2011 it reached 28 °C (82.4 °F). However in recent years both of these months have also had snowfall. Temperature extremes range from −10 °C (14.0 °F) to 37.9 °C (100.2 °F).
