126-581: Coulsdon ( / ˈ k uː l z d ən / , traditionally pronounced / ˈ k oʊ l z d ən / ) is a town in south London , England, within the London Borough of Croydon . Coulsdon was an ancient parish in the county of Surrey that included the settlements of Purley and Kenley . It was merged with Sanderstead in 1915 to form the Coulsdon and Purley Urban District and has formed part of Greater London since 1965. The location forms part of
252-472: A Bronze Age bridge were found on the south River Thames foreshore, upstream from Vauxhall Bridge . Two of the timbers were radiocarbon dated to 1750–1285 BC. In 2010, foundations of a large timber structure, dated to 4800–4500 BC, were found on the Thames' south foreshore downstream from Vauxhall Bridge. Both structures are on the south bank of the Thames, where the now-underground River Effra flows into
378-482: A century ago. Because land transportation of minerals like limestone and coal was difficult in the pre-industrial era, they were distributed by sea, and lime was most often manufactured at small coastal ports. Many preserved kilns are still to be seen on quaysides around the coasts of Britain. Permanent lime kilns fall into two broad categories: "flare kilns" also known as "intermittent" or "periodic" kilns; and "draw kilns" also known as "perpetual" or "running" kilns. In
504-434: A flare kiln, a bottom layer of coal was built up and the kiln above filled solely with chalk. The fire was alight for several days, and then the entire kiln was emptied of the lime. In a draw kiln, usually a stone structure, the chalk or limestone was layered with wood, coal or coke and lit. As it burnt through, lime was extracted from the bottom of the kiln, through the draw hole. Further layers of stone and fuel were added to
630-447: A junction with that trunk (long-distance) route (which later becomes the M23 ). The soil is dry, and water was obtained even in 1912 by deep wells here in the chalk. This dry valley in the chalk, Smitham Bottom, has a watercourse below, the water of which in until the 16th century occasionally in times of flood ran here but after this, inexplicably, waits to break out as far as at the foot of
756-556: A large proportion of new installations if energy costs are less important. The early use of simple rotary kilns had the advantages that a much wider range of limestone size could be used, from fines upwards, and undesirable elements such as sulfur can be removed. On the other hand, fuel consumption was relatively high because of poor heat exchange compared with shaft kilns, leading to excessive heat loss in exhaust gases. Old fashioned "long" rotary kilns operate at 7 to 10 MJ/kg. Modern installations partially overcome this disadvantage by adding
882-542: A larger area, similar in size to Greater London, although some outer districts are excluded and some just outside included. The Greater London boundary has been aligned to the M25 motorway in places. Further urban expansion is now prevented by the Metropolitan Green Belt , although the built-up area extends beyond the boundary in places, producing a separately defined Greater London Urban Area . Beyond this
1008-403: A population density of 802 per acre (325 per hectare). In addition to the growing number of stores selling goods, such as Harding, Howell & Co. —one of the first department stores —located on Pall Mall , the streets had scores of street sellers . London's overcrowded conditions led to cholera epidemics, claiming 14,000 lives in 1848, and 6,000 in 1866. Rising traffic congestion led to

Old Coulsdon occupies
1638-464: A single pot. As production was cut back, the two side arches were blocked up, but were restored in 1989 by English Heritage . The development of the national rail network made the local small-scale kilns increasingly unprofitable, and they gradually died out through the 19th century. They were replaced by larger industrial plants. At the same time, new uses for lime in the chemical , steel and sugar industries led to large-scale plants. These also saw
1764-708: A stabilizer in mud renders and floors. According to finds at 'Ain Ghazal in Jordan, Yiftahel in Israel, and Abu Hureyra in Syria dating to 7500–6000 BCE, the earliest use of lime was mostly as a binder on floors and in plaster for coating walls. This use of plaster may in turn have led to the development of proto-pottery, made from lime and ash. In mortar, the oldest binder was mud. According to finds at Catal Hüyük in Turkey, mud
1890-551: A temperate oceanic climate ( Köppen : Cfb ). Rainfall records have been kept in the city since at least 1697, when records began at Kew . At Kew, the most rainfall in one month is 7.4 inches (189 mm) in November 1755 and the least is 0 inches (0 mm) in both December 1788 and July 1800. Mile End also had 0 inches (0 mm) in April 1893. The wettest year on record is 1903, with a total fall of 38.1 inches (969 mm) and
2016-1449: A trading depot in the Marlpit Lane quarry from 1923. It was named the "Ullswater trading estate". The limeworks closed in 1961, and a park now lies in its place. The town's spelling, pronunciation and location have changed. Coulsdon originally referred to the area now known as Old Coulsdon . The name derives from Cuðrædsdun via Cullesdone pre-1130, Culesdone pre-1190, Cullisdon 1242, Culesdene 1255, Colendone c1270, Kulisdon 1279, Collesdon 1288, Cullesdon 1323, Colleston 1324, Coulesdon 1346, Cullysdon 1377, Colynsdon 1428, Colysdon 1439, Collysdon 1563, Cowlesdon 1557, Coulsdon 1597, Cowisden 1604, Couldisdon 1610, Couldesdon 1675, Culsdon 1678, Colsdon 1724.

A memorial park and recreation ground was purchased from the Byrons by Coulsdon and Purley Urban District Council and Hall & Co Ltd in 1920, it was opened in 1921. The London Loop footpath passes through Happy Valley and Farthing Downs between Hamsey Green and Banstead . The Coulsdon section
2394-421: Is a significant carbon dioxide emitter. The manufacture of one tonne of calcium oxide involves decomposing calcium carbonate, with the formation of 785 kg of CO 2 in some applications, such as when used as mortar ; this CO 2 is later re-absorbed as the mortar goes off. If the heat supplied to form the lime (3.75 MJ/kg in an efficient kiln) is obtained by burning fossil fuel it will release CO 2 : in
2520-562: Is agreed that the name came into these languages from Common Brythonic ; recent work tends to reconstruct the lost Celtic form of the name as * Londonjon or something similar. This was then adapted into Latin as Londinium and borrowed into Old English. Until 1889, the name "London" applied officially only to the City of London , but since then it has also referred to the County of London and to Greater London . In 1993, remains of
2646-413: Is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient. The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns. The first were simple shaft kilns, similar in construction to blast furnaces . These are counter-current shaft kilns. Modern variants include regenerative and annular kilns. Output

At the heart of the geographical feature Smitham Bottom (where three dry valleys merge into one)
3276-564: Is known as London . It is the capital of the United Kingdom and of England by convention rather than statute. 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. Greater London encompasses a total area of 611 square miles (1,583 km ) an area which had
3402-459: Is more typical. Due to temperature peak at the burners up to 1200 °C in a shaft kiln conditions are ideal to produce medium and hard burned lime. These typically consist of a pair of shafts, operated alternately. First, when shaft A is the "primary" and B the "secondary" shaft, the combustion air is added from the top of shaft A, while fuel somewhat below via burner lances. The flame is top-bottom. The hot gases pass downward, cross to shaft B via

4032-434: Is then used to pressurize the middle annular zone of the kiln. Air spreading outward from the pressurized zone causes counter-current flow upwards, and co-current flow downwards. This again produces a long, relatively cool calcining zone. Fuel consumption is in 4 to 4.5 MJ/kg range and the lime is typically medium burned. Rotary kilns started to be used for lime manufacture at the start of the 20th century and now account for

8442-415: The United Kingdom's population and over 16% of England's population. The Greater London Built-up Area is the fourth-most populous in Europe, with about 9.8 million inhabitants as of 2011. The London metropolitan area is the third-most populous in Europe, with about 14 million inhabitants as of 2016, making London a megacity . Four World Heritage Sites are located in London: Kew Gardens ;
8568-405: The Viking incursions formally agreed by the Danish warlord , Guthrum and the West Saxon king Alfred the Great in 886. The Anglo-Saxon Chronicle records that Alfred "refounded" London in 886. Archaeological research shows this involved abandonment of Lundenwic and a revival of life and trade within the old Roman walls . London then grew slowly until a dramatic increase in about 950. By
8694-516: The amount of fuel used. Because there were large temperature differences between the center of the charge and the material close to the wall, a mixture of underburned (i.e. high loss on ignition ), well-burned and dead-burned lime was normally produced. Typical fuel efficiency was low, with 0.5 tonnes or more of coal being used per tonne of finished lime (15 MJ/kg). Lime production was sometimes carried out on an industrial scale. One example at Annery in North Devon , England , near Great Torrington ,
8820-408: The case of coal fuel 295 kg/t; in the case of natural gas fuel 206 kg/t. The electric power consumption of an efficient plant is around 20 kWh per tonne of lime. This additional input is the equivalent of around 20 kg CO 2 per ton if the electricity is coal-generated. Thus, total emission may be around 1 tonne of CO 2 for every tonne of lime even in efficient industrial plants, but
8946-437: The centre of the British press. The invasion of Amsterdam by Napoleonic armies led many financiers to relocate to London and the first London international issue was arranged in 1817. Around the same time, the Royal Navy became the world's leading war fleet, acting as a major deterrent to potential economic adversaries. Following a fire in 1838, the Royal Exchange was redesigned by William Tite and rebuilt in 1844. The repeal of
9072-532: The chalk in Croydon and Beddington, running through it. Marlpit (a former chalk quarry) is the town's Marlpit Industrial / Business Park estate, which is strong in storage, distribution and technology. The Mount or Clockhouse is a square neighbourhood on a hill plateau with marked borders along three residential roads from Coulsdon, one of which continues from the town centre as the London Loop path, via
9198-536: The city's metropolis. The City of London at its core once comprised the whole settlement, but as its urban area grew, the Corporation of London resisted attempts to amalgamate the city with its suburbs , causing "London" to be defined several ways. Forty per cent of Greater London is covered by the London post town , in which 'London' forms part of postal addresses. The London telephone area code (020) covers
9324-412: The city, to intimidate the inhabitants. In 1097, William II began building Westminster Hall , near the abbey. It became the basis of a new Palace of Westminster . In the 12th century, the institutions of central government, which had hitherto followed the royal English court around the country, grew in size and sophistication and became increasingly fixed, for most purposes at Westminster , although
9450-600: 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). The London Fire Brigade is the statutory fire and rescue service for Greater London, run by the London Fire and Emergency Planning Authority . It is the third largest fire service in the world. National Health Service ambulance services are provided by
9576-405: The comprehensive University College London . It is the most visited city in Europe and has the world's busiest city airport system . The London Underground is the world's oldest rapid transit system. London's diverse cultures encompass over 300 languages. The 2023 population of Greater London of just under 10 million made it Europe's third-most populous city , accounting for 13.4% of
9702-626: The creation of the Greater London Authority . To mark the 21st century, the Millennium Dome , London Eye and Millennium Bridge were constructed. On 6 July 2005 London was awarded the 2012 Summer Olympics , as the first city to stage the Olympic Games three times. On 7 July 2005, three London Underground trains and a double-decker bus were bombed in a series of terrorist attacks . In 2008, Time named London alongside New York City and Hong Kong as Nylonkong , hailing them as
9828-559: The creation of the London Underground , the world's first urban rail network . The Metropolitan Board of Works oversaw infrastructure expansion in the capital and some surrounding counties; it was abolished in 1889 when the London County Council was created out of county areas surrounding the capital. From the early years of the 20th century onwards, teashops were found on High Streets across London and
9954-557: The development of more efficient kilns. A lime kiln erected at Dudley , West Midlands (formerly Worcestershire ) in 1842 survives as part of the Black Country Living Museum which opened in 1976, although the kilns were last used during the 1920s. It is now among the last in a region which was dominated by coalmining and limestone mining for generations until the 1960s. The theoretical heat (the standard enthalpy ) of reaction required to make high-calcium lime
10080-713: The driest is 1921, with a total fall of 12.1 inches (308 mm). The average annual precipitation amounts to about 600mm, which is half the annual rainfall of New York City . Despite relatively low annual precipitation, London receives 109.6 rainy days on the 1.0mm threshold annually. London is vulnerable to climate change , and there is concern among hydrological experts that households may run out of water before 2050. Temperature extremes in London range from 40.2 °C (104.4 °F) at Heathrow on 19 July 2022 down to −17.4 °C (0.7 °F) at Northolt on 13 December 1981. Records for atmospheric pressure have been kept at London since 1692. The highest pressure ever reported
10206-609: The first Muslim mayor of a major Western capital. The mayor's statutory planning strategy is published as the London Plan , which was most recently revised in 2011. The local authorities are the councils of the 32 London boroughs and the City of London Corporation . They are responsible for most local services, such as local planning, schools, libraries, leisure and recreation, social services , local roads and refuse collection. Certain functions, such as waste management , are provided through joint arrangements. In 2009–2010
10332-400: The form of lime called quicklime ( calcium oxide ). The chemical equation for this reaction is This reaction can take place at anywhere above 840 °C (1,540 °F), but is generally considered to occur at 900 °C (1,650 °F) (at which temperature the partial pressure of CO 2 is 1 atmosphere ), but a temperature around 1,000 °C (1,830 °F) (at which temperature
10458-470: The heart of Old Coulsdon and incorporates a children's play area and recreational green space. In total, Grange Park represents local green space of around 8 acres. Places of worship include: Athletics: The Old Coulsdon Hash House Harriers (or "OCH3") is a local hashing group. Gordon Pirie (1931–1991), an English long-distance runner lived in Coulsdon and was a member of South London Harriers, one of
10584-402: The heat loss of the regenerative kiln is minimal, fuel consumption is as low as 3.6 MJ/kg. Due to these features the regenerative kilns are today mainstream technology under conditions of substantial fuel costs. Regenerative kilns are built with 150 to 800 t/day output, 300 to 450 being typical. These contain a concentric internal cylinder. This gathers pre-heated air from the cooling zone, which
10710-462: The kilns were shut down. The present-day area, though having no town amenities as such, markets itself as a tourist destination. The ruins of the lime kilns can still be seen today. A lime kiln also existed in Wool Bay , South Australia . The large kiln at Crindledykes near Haydon Bridge , Northumbria, was one of more than 300 in the county. It was unique to the area in having four draw arches to
10836-554: The last bricks to be made locally at Crossways (at Coulsdon Road, Old Coulsdon). In 1854, to avoid the court, he adjusted the paths of some local roads, and created a gated drive from the public road. In 1863, Edmund Byron inherited the title. After his use of the inclosure acts was curtailed when he lost a case in 1877 at the Court of Chancery , large areas were sold in 1883 to the Corporation of London. The importance of this event
10962-444: The late 1990s, but these were delayed and then cancelled. An approved development of the former site of Cane Hill Hospital by Barratt Developments and David Wilson Homes , an associated organisation, gained planning permission, and started in about 2015, with intent to create over six hundred new dwellings. In 2013, Barratt published a Public Consultation document and report of feedback. Some residents protested concerns relating to
11088-470: The likely effect on local infrastructure, including access routes, the proposed mix of housing, transport, notably road traffic, and the provision of educational services. In 2016 planning application approvals were finalised and the development of 677 homes on the 210-acre site was later completed in November, 2021. In 1883, to prevent further loss of Common lands arising from the Inclosure Acts ,
11214-408: The lime at the bottom. A fan draws the gases through the kiln, and the level in the kiln is kept constant by adding feed through an airlock. As with batch kilns, only large, graded stone can be used, in order to ensure uniform gas-flows through the charge. The degree of burning can be adjusted by changing the rate of withdrawal of lime. Heat consumption as low as 4 MJ/kg is possible, but 4.5 to 5 MJ/kg
11340-640: The location of its original headquarters in a road called Great Scotland Yard in Whitehall. The City of London has its own police force – the City of London Police . First worn by Met police officers in 1863, the custodian helmet has been called a "cultural icon" and a "symbol of British law enforcement". Introduced by the Met in 1929, the blue police telephone box (basis for the TARDIS in Doctor Who )
11466-409: The mayor's budget proposals each year. The GLA has responsibility for the majority of London's transport system through its functional arm Transport for London (TfL), it is responsible for overseeing the city's police and fire services, and also for setting a strategic vision for London on a range of issues. The headquarters of the GLA is City Hall , Newham. The mayor since 2016 has been Sadiq Khan ,
11592-753: The most museums , art galleries, libraries, and cultural venues in the UK, including the British Museum , National Gallery , Natural History Museum , Tate Modern , British Library , and numerous West End theatres. Important sporting events held in London include the FA Cup Final , the Wimbledon Tennis Championships , and the London Marathon . It became the first city to host three Summer Olympic Games upon hosting
11718-675: The most diverse cities in the world. 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 soup fogs " for which London had been notorious, and had earned it the nickname the "Big Smoke". Starting mainly in the mid-1960s, London became a centre for worldwide youth culture , exemplified by the Swinging London sub-culture associated with
11844-682: The name is ‘hill of a man called Cūthrǣd’, (from OE pers. name + dūn, a hill). Alternatively the name originates from the Celtic or primitive Welsh "cull", meaning a leather bag, scrotum, bosom, womb or belly. The current town centre appears as Leydown Cross (1738) or Leaden Cross (1800) and Smitham Bottom. In 1905, the parish council, and then the Post Office renamed "Smitham bottom" as "Coulsdon". The name "Smitham Bottom" has also changed. Smetheden (1331), Smithdenbottom (1536), Smythedean(e)(1548), Smythden Bottom (1588), Smitham Bottom (1719) Coulsdon
11970-467: The old Roman city. By about 680 the city had become a major port again, but there is little evidence of large-scale production. From the 820s repeated Viking assaults brought decline. Three are recorded; those in 851 and 886 succeeded, while the last, in 994, was rebuffed. The Vikings applied Danelaw over much of eastern and northern England, its boundary running roughly from London to Chester as an area of political and geographical control imposed by
12096-573: The oldest and most successful athletics club in Britain. The club has been based in Coulsdon since 1913, and remains there to this day. The club competes in cross-country, road running and track and field events, and trains from its Coulsdon HQ three times a week. The club has been heavily involved in recent years in building an eight lane all weather running track at Woodcote School. It also has an active and successful triathlon section. Bare-knuckle boxing fights were held at Smitham Bottom. Records exist of fights in 1788 and 1792. London London
12222-448: The partial pressure of CO 2 is 3.8 atmospheres ) is usually used to make the reaction proceed quickly. Excessive temperature is avoided because it produces unreactive, "dead-burned" lime. Slaked lime ( calcium hydroxide ) can be formed by mixing quicklime with water. Because it is so readily made by heating limestone, lime must have been known from the earliest times, and all the early civilizations used it in building mortars and as
12348-490: The principal city of the Roman province of Britannia in 100. At its height in the 2nd century, Roman London had a population of about 60,000. With the early 5th-century collapse of Roman rule, the walled city of Londinium was effectively abandoned, although Roman civilisation continued around St Martin-in-the-Fields until about 450. From about 500, an Anglo-Saxon settlement known as Lundenwic developed slightly west of
12474-466: The resources, and it was rapidly developing the dignity and the political self-consciousness appropriate to a national capital ." After winning the Battle of Hastings , William, Duke of Normandy was crowned King of England in newly completed Westminster Abbey on Christmas Day 1066. William built the Tower of London , the first of many such in England rebuilt in stone in the south-eastern corner of
12600-641: The rest of Britain, with Lyons , who opened the first of their chain of teashops in Piccadilly in 1894, leading the way. The tearooms, such as the Criterion in Piccadilly, became a popular meeting place for women from the suffrage movement. The city was the target of many attacks during the suffragette bombing and arson campaign , between 1912 and 1914, which saw historic landmarks such as Westminster Abbey and St Paul's Cathedral bombed. London
12726-450: The role of "primary" and "secondary" shaft. The kiln has three zones: preheating zone on the top, burning zone in the middle, and cooling zone close to the bottom. The cycling produces a long burning zone of constant, relatively low temperature (around 950 °C) that is ideal for the production of high quality soft burned reactive lime. With exhaust gas temperatures as low as 120 °C and lime temperature at kiln outlet in 80 °C range
12852-401: The royal treasury came to rest in the Tower . While the City of Westminster developed into a true governmental capital, 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 some 18,000; by 1300 it had grown to nearly 100,000. With
12978-414: The same size. Above a certain diameter, the half-burned charge would be likely to collapse under its own weight, extinguishing the fire. So kilns always made 25–30 tonnes of lime in a batch. Typically the kiln took a day to load, three days to fire, two days to cool and a day to unload, so a one-week turnaround was normal. The degree of burning was controlled by trial and error from batch to batch by varying
13104-546: The sea. London is the seat of the Government of the United Kingdom . Many government departments, as well as the prime minister's residence at 10 Downing Street , are based close to the Palace of Westminster , particularly along Whitehall . There are 75 members of Parliament (MPs) from London; As of June 2024 , 59 are from the Labour Party , 9 are Conservatives , 6 are Liberal Democrats and one constituency
13230-461: The so-called "channel" and pass upward to exhaust of shaft B. At same time in both shafts cooling air is added from the bottom to cool the lime and to make exhaust of gases via the bottom of the kiln impossible via maintaining a positive pressure. The combustion air and cooling air leave the kiln jointly via exhaust on top of shaft B, preheating the stone. The direction of flow is reversed periodically (typically 5–10 times per hour) shaft A and B changing
13356-648: The south-east of the district. Scattered, rather than clustered, are six buildings listed for their national heritage and architectural value, at Grade II. Two categories above this, in the highest class, Grade I, is the Church of St John the Evangelist. This is by the recreation ground, shortly after Marlpit Lane has been joined by Coulsdon Road, from the north. St John's is late thirteenth century with extensive later additions, made of flint and rubble with much brick patching. Its nave spans two (window) bays. Older still
13482-424: The start of 2018 to mid April 2018. Funding cuts to police in London are likely to have contributed to this, though other factors are involved. However, homicide figures fell in 2022 with 109 recorded for the year, and the murder rate in London is much lower than other major cities around the world. London, also known as Greater London , is one of nine regions of England and the top subdivision covering most of
13608-753: The theatres in the 1640s. The ban on theatre was lifted during the Restoration in 1660, and London's oldest operating theatre, Drury Lane , opened in 1663 in what is now the West End theatre district. By the end of the Tudor period in 1603, London was still compact. There was an assassination attempt on James I in Westminster, in the Gunpowder Plot of 5 November 1605. In 1637, the government of Charles I attempted to reform administration in
13734-415: The top. The common feature of early kilns was an egg-cup shaped burning chamber, with an air inlet at the base (the "eye"), constructed of brick. Limestone was crushed (often by hand) to fairly uniform 20–60 mm (1– 2 + 1 ⁄ 2 in) lumps – fine stone was rejected. Successive dome-shaped layers of limestone and wood or coal were built up in the kiln on grate bars across the eye. When loading
13860-715: The unique governmental status of the City . In the English Civil War , the majority of Londoners supported the Parliamentary cause. After an initial advance by the Royalists in 1642, culminating in the battles of Brentford and Turnham Green , London was surrounded by a defensive perimeter wall known as the Lines of Communication . The lines were built by up to 20,000 people, and were completed in under two months. The fortifications failed their only test when
13986-639: The world's three most influential global cities . In January 2015, Greater London's population was estimated to be 8.63 million, its highest since 1939. During the Brexit referendum in 2016, the UK as a whole decided to leave the European Union , but most London constituencies voted for remaining. However, Britain's exit from the EU in early 2020 only marginally weakened London's position as an international financial centre. The administration of London
14112-1078: Was bombed by the Germans in the First World War , and during the Second World War , the Blitz and other bombings by the German Luftwaffe killed over 30,000 Londoners, destroying large tracts of housing and other buildings across the city. The tomb of the Unknown Warrior , an unidentified member of the British armed forces killed during the First World War, was buried in Westminster Abbey on 11 November 1920. The Cenotaph , located in Whitehall ,
14238-402: Was an ancient parish in the county of Surrey that included the settlements of Purley and Kenley . In 1894 it became part of Croydon Rural District . The population of the parish had almost doubled between 1901 and 1911. In 1915 the rural district was split up and Coulsdon was merged with Sanderstead to form the Coulsdon and Purley Urban District . In 1965 Coulsdon and Purley became part of
14364-687: Was built in the 80 years from 1890 to 1970. The area developed mixed suburban, and in its centre urban, housing: The whole aspect of the parish has been completely transformed during the last twenty years by building. It was a little while ago entirely rural with a few new houses scattered along the line of the railway and up the valley towards Caterham, whence another deep depression in the chalk runs down to Smitham Bottom. Now there are continuous rows of villas and cottages and shops from Croydon to south of Coulsdon station. The valley and routes in Smitham Bottom encouraged some early settlements. An inn,
14490-399: Was complete, the kiln was kindled at the bottom, and the fire gradually spread upwards through the charge. When burnt through, the lime was cooled and raked out through the base. Fine ash dropped out and was rejected with the "riddlings". Only lump stone could be used, because the charge needed to "breathe" during firing. This also limited the size of kilns and explains why kilns were all much
14616-518: Was known as a "lazy kiln". In the late 19th and early 20th centuries the town of Waratah in Gippsland , Victoria , Australia produced a majority of the quicklime used in the city of Melbourne as well as around other parts of Gippsland. The town, now called Walkerville , was set on an isolated part of the Victorian coastline and exported the lime by ship. When this became unprofitable in 1926
14742-527: Was made up of three kilns grouped together in an 'L' shape and was situated beside the Torrington canal and the River Torridge to bring in the limestone and coal, and to transport away the calcined lime in the days before properly metalled roads existed. Sets of seven kilns were common. A loading gang and an unloading gang would work the kilns in rotation through the week. A rarely used kiln
14868-507: Was named the 'Stoats Nest Quarry'. The works had its own internal railway system which connected to nearby main lines. In 1898, the Hall family were refused permission (by their landlord) to build cement works on the Coulsdon site. The lime principally supplied for waterworks, gas works and tanneries. Demand reduced in 1902 when the Army changed from leather to webbing equipment. And in 1905 there
14994-462: Was no longer demand from the gasworks. Between 1905 and 1910 chalk was supplied for the Halls' cement works at Beddington. In 1905, 13,000 tons of chalk were sent by rail from Coulsdon. By 1918, it was processing lime for use as fertilizer. In 1920, the Hall company purchased 102 acres from their landlord, Byron. This offered their full benefit of the railways and kilns on the land. Halls maintained
15120-437: Was once a common sight throughout London and regional cities in the UK. The British Transport Police are responsible for police services on National Rail , London Underground , Docklands Light Railway and Tramlink services. The Ministry of Defence Police is a special police force in London, which does not generally become involved with policing the general public. The UK's domestic counter-intelligence service ( MI5 )
15246-429: Was owned by three generations of the Byron family, who had already purchased the sub-manor of Hooley. In 1801, the Byron family moved to live at Hooley House. Then, having sold a large amount of land in 1838 to the 'London to Brighton railway company', they moved from Hooley House to Portnall's Farm. In 1850, Hartley Farm was demolished and Coulsdon Court was built by Thomas Byron. It was said to have been constructed of
15372-556: Was reported in The Times . He also sold and gave away various plots. In 1921, Edmund Byron died. The remaining lands owned by the Byrons were sold. Land and manorial rights were passed to the Coulsdon and Purley Urban District Council. For many centuries, the lands contained several farms and manors and only on the coming of the railway were a few wealthy people from outside the traditional borders attracted to build grand houses, by 19th century descriptions, such as: This parish, which
15498-417: Was soon followed by clay, and then by lime in the 6th millennium BCE. Knowledge of its value in agriculture is also ancient, but agricultural use only became widely possible when the use of coal made it cheap in the coalfields in the late 13th century, and an account of agricultural use was given in 1523. The earliest descriptions of lime kilns differ little from those used for small-scale manufacture
15624-465: Was supervised by polymath Robert Hooke . In 1710, Christopher Wren 's masterpiece, St Paul's Cathedral , was completed, replacing its medieval predecessor that burned in the Great Fire of 1666. The dome of St Paul's dominated the London skyline for centuries, inspiring the artworks and writing of William Blake , with his 1789 poem " Holy Thursday " referring to 'the high dome of Pauls'. During
15750-501: Was the first of the 24 to be opened. Grange Park was obtained partly by Public Subscription but mostly by Coulsdon and Purley Urban District Council in 1929 from the owners of the Coulsdon Court Golf Course. The land was sold for use as an open space or pleasure and recreation ground. Grange Park was formerly part of Squire Byrons Coulsdon Court Estate. Grange Park is situated in a designated conservation area in
15876-524: Was unveiled on the same day, and is the focal point for the National Service of Remembrance held annually on Remembrance Sunday , the closest Sunday to 11 November. The 1948 Summer Olympics were held at the original Wembley Stadium , while London was still recovering from the war. From the 1940s, London became home to many immigrants, primarily from Commonwealth countries such as Jamaica, India, Bangladesh and Pakistan, making London one of
