Isleworth ( ) is a suburban town in the London Borough of Hounslow, west London, England. Its main retail street London Road becomes Hounslow High Street and adjoining Treaty Centre for shopping centre only a few hundred metres away from its westernmost point. No physical signs mark this boundary, which reflects how Isleworth contained the east of Hounslow, originally.

Isleworth sits west of the River Thames and its tributary the River Crane and the original area of settlement, alongside the Thames, is known as Old Isleworth. The northwest corner of the town, bordering on Osterley to the north and Lampton to the west, is known as Spring Grove. Both postally and historically Osterley is part of Isleworth, however it has its own tube station.

Isleworth's former Thames frontage of approximately one mile, excluding that of the upmarket attractions of Syon Park, was reduced to little over half a mile in 1994 when a borough boundary realignment was effected in order to unite the district of Margaret's wholly within London Borough of Richmond upon Thames. As a result, the riverside is those parts overlooking the islet of Isleworth Ait: the short-length River Crane flows into the Thames south of the Isleworth Ait, and its artificial distributary the Duke of Northumberland's River west of the Isleworth Ait, one of two Colne distributaries constructed for aesthetic reasons between 1600 and 1750.

The town is the birthplace of broadcaster David Attenborough.

History

Roman and Anglo Saxon

Excavations around the eastern end of the Syon Park estate have unearthed evidence of a Romano-British settlement. 'Gislheresuuyrth', meaning in Old English Enclosure belonging to [a man called] Gīslhere, is first referred to as a permanent settlement in an Anglo-Saxon charter in the year 695. The Domesday Book says that during the reign (1042–1066) of Edward the Confessor the manor belonged to "Earl Algar" (probably Ælfgar of Mercia), and a modern road off South Street today carries his name.

Granted to Saint Valeri Barons

Isleworth was a well-cultivated farming and trading settlement, more valuable than many of its neighbours at the time of the Norman Conquest in 1066. For centuries it continued to stretch from the Middlesex bank of the Thames in the east, west to include the centre of what was its hamlet then chapelry Hounslow (including the medieval founded Hounslow Priory) and to bound Whitton, as far north so as to bound Southall (in Hayes parish at the time), and as south as to bound Twickenham. The Domesday Book (1086) as Gistelesworde records its 55 ploughlands, 118 households and amount rendered, £72 per year, to its feudal system overlords. After the Conquest, successive Norman barons of the Saint Valeri family held the manor of Isleworth but there is no evidence that they lived there – it being held as a source of rentals and subinfeudation/lettings/charitable giving power. One of the later barons gave several manorial rents and privileges to London's Hospital of Saint Giles. He also gave the church and advowson to the Abbey of Saint Valeri, at the mouth of the Somme in Picardy.

Transfer to Earldom of Cornwall

thumb|left|160px|Coat of arms of Richard, First Earl of Cornwall

In 1227, when he took control of England from his childhood regents, Henry III seized Isleworth manor and other property of the Saint Valeri family and gave the manor to his brother, Richard, 1st Earl of Cornwall. He built a new moated manor house, which is described in the Black Book of the Exchequer – having a tiled roof, chimney, two bedchambers and an inner courtyard. Outwith the moat was an outer courtyard with a number of buildings for servants and supplies, and a short distance away was a watermill. The exact location is unknown, but a report long ago of 'Moated Place' puts the likely place between the Northumberland Arms and Twickenham Road, with the watermill being near Railshead, on the only suitable water then existing, the Crane. The castle-like stone church tower by the river remains from this period, see below.

Transfer of Manor to Syon Monastery

In 1415 Henry V granted nuns from the Swedish Bridgettine order land on the bank of the Thames, firstly in Twickenham opposite his new Sheen Palace, where they built their first house Syon Monastery. In 1422 Henry V transferred ownership of Isleworth Manor from the Duchy of Cornwall to Syon Monastery, which in 1431 was selected for the new site within their manor to rebuild their monastery. This is the site of the present Syon House.

Granted to Duke of Somerset

Henry VIII demolished most of Syon Monastery after 1539 and the site and manor was granted to Edward Seymour, 1st Duke of Somerset. It was Seymour who built Syon House in 1548. Lady Jane Grey was taken from here to the Tower by Royal barge in anticipation of her being crowned Queen of England.

Acquired by Earl of Northumberland

Forty-six years later, in 1594 Queen Elizabeth I granted a lease of the manor of Syon to Henry Percy, 9th Earl of Northumberland on his marriage to Dorothy Devereux the younger daughter of Walter Devereux, 1st Earl of Essex, who later received a grant of the freehold from King James I in 1604. It has remained in the possession of the Percy family, now the Dukedom of Northumberland, for over four hundred years. The Royalist army occupied the house during the Battle of Brentford in November 1642. Syon Park was rebuilt and landscaped by the Adam brothers and "Capability" Brown between 1766 and 1773. It became the new home of the Dukes of Northumberland when Northumberland House in the Strand was demolished in 1874.thumb|right|250px|Georgian houses in Church Street, next to the parish church and facing the Thames

Georgian and Victorian times

Much of Isleworth became orchards in the 18th century (including part of Hugh Ronalds' renowned nursery), and then market gardens in the 19th century, supplying the London markets. Lower Square and Church Street still have buildings dating from the 18th and early 19th centuries. A striking element of this period was the establishment in Isleworth of many mansions and large houses, principally for aristocrats and high achievers. This phenomenon arose owing mainly to the collection of royal and noble residences and ecclesiastical establishments that already existed nearby. The subject is examined in depth in the "Notable houses" section.

There is evidence of a Black community in Isleworth in the 18th century. This community was primarily made up of enslaved people of colour, from Africa, Asia or the Caribbean. Some of these people had fled from bondage and chose to seek their freedom in the streets of London. With very few exceptions, little is known about people of colour in 18th century London. However, as a result of contemporary sources like advertisements seeking the capture and return of runaway slaves, an insight can be gained into the lives of two people, Marina Dellap and Prince, who resided in the area in 1765.

Workhouse and former Hospitals

Brentford Workhouse Infirmary and West Middlesex Hospital before 1980

The Brentford Poor Law Union had a workhouse built in 1838 covering much land to the east of Twickenham Road in Isleworth. At the turn of the 20th century, this was totally rebuilt as an infirmary, with a much larger workhouse newly erected in the grounds. This infirmary functioned until 1920, when it became 'West Middlesex Hospital'. In 1931 it was upgraded to a county hospital, but in 1948 (under the NHS) 'County' was dropped from its title. It later became a teaching hospital, and added 'University' to its title in 1980. The Victorian buildings were closed in 2003, and largely redeveloped as housing, called Union Lane, after the original workhouse. The hospital was rebuilt on the adjacent site.

Percy House Auxiliary Military Hospital

Within the old union workhouse complex stood a school, facing Twickenham Road, called Percy House – Percy being the surname of the dukes of Northumberland. Owing to its gradual disuse as a school it was adapted to function as a military hospital during World War I of 1914–18. From 1915 onwards it treated some 5,000 war-wounded soldiers, and ceased operation at the end of 1918. Among the VAD nurses was Sophia Duleep Singh. The building was demolished in 1978.

20th century

The first half of the 20th century for Isleworth generally was characterised by a very substantial amount of artisan and white-collar residential development throughout the town, on many market gardens. The former western area was ceded to the town and parish of Hounslow, which was invested as a civil parish in 1927. This period also included the building of several new factories and offices, mostly in the far north-east by the eastern limit (with Brentford). This rapid spread of building transformed the nature of Isleworth's layout in the space of just fifty years, from an agrarian pattern to an urban one.

Isleworth's former Thames frontage of about one mile (excluding within the Syon estate), has falled to about since 1994 when two boroughs' boundaries were tweaked by the UK's Local Government Minister to shift land to the London Borough of Richmond upon Thames. This unified the district of St Margarets, Twickenham, named after a former house there. The house stood in its Ailsa estate a Victorian garden suburb and which has a railway station next to its other parts and has several seamless bridges over the south channel of the Crane, but which accordingly had been cross-borough.

Geography

thumb|NoiseIf deemed to still include Osterley, elevations range from in the northwest to by the Thames OD. The boundaries are longstanding, subject to twentieth-century western and southern circonscriptions: Isleworth is east of the town of Hounslow which has more retail and offices, in the borough of that name; west of the River Thames; north of its tributary and the northernmost confluence of the Crane; and south of the crest by the M4 motorway separating the Brent and Crane catchments. Half of the River Crane flows into the Thames south of the Ait, and its newest distributary the Duke of Northumberland's River flows toward the Ait's midpoint.

Isleworth is on the Heathrow flight path. It experiences a high level of airplane noise daily. Hundreds of flights per day go over Isleworth. Both flight paths 27R and 27L go through Isleworth. The average daily noise level at Isleworth station is 61 decibels.

Politics

Isleworth is part of the Brentford and Isleworth constituency for elections to the House of Commons.

Isleworth resembles Isleworth ward for elections to its council, Hounslow London Borough Council.

Amenities

Isleworth is home to Isleworth Crown Court whose original remit has been expanded to include judicial work formerly conducted at the Middlesex Crown Court; an extension to create six new courtrooms was completed in 2009.

The town's municipal facilities include a library, a leisure centre with swimming pool, a gymnasium, four recreation grounds, and a town (community) hall.

There used to be a film studio in Worton Road, Isleworth. Known variously as Worton Hall Studios and Isleworth Studios, its most notable film was The African Queen (1951) starring Humphrey Bogart and Katharine Hepburn. After it closed, the premises became a Mining Research Establishment for the National Coal Board. It is now a subdivided but in a larger set of light industry units.

Osterley/Isleworth has been home to satellite television broadcaster Sky since its launch in 1989 by Rupert Murdoch. Originally centred on Grant Way, the sprawling campus around Gillette Corner once took in New Horizons Court and is now the sole occupier of the Centaurs Business Park, with offices, studios, production space, research and development facilities, plus a dedicated energy centre including a wind turbine by Arup Associates.

The boat Cathja is moored in Old Isleworth. This is a 38-metre barge houses a charity since 1996. It offers people with mental disabilities an opportunity to hone their artistic skills, and hosts sculpture The Heron by Martin Cotts.

Isleworth was home to opera group Isleworth Baroque (now Richmond Opera) from 2002 to 2015.

Hospitals

West Middlesex University Hospital

This is a major acute hospital on the Twickenham Road, Isleworth, with 394 beds, providing the full range of services expected of a general hospital. It serves residents of the London boroughs of Hounslow and Richmond. As a university hospital it is affiliated with Imperial College London. A programme of building, renovation and modernisation in recent years has resulted in the hospital offering modern facilities.

Transport

Roads

The principal road in Isleworth is the London Road (A 315), which closely tracks the later dubbed Devil's Highway (Roman Britain) rising here to gravelly heathland en route to Silchester, from where other roads led to Bath, Winchester and Salisbury; one historian Bate combines Latin with Anglo-Saxon to call this "Tamesis Street"; stressing how for instance it took until the year 1280 for a Maidenhead Bridge, whereas on this route, the first Staines Bridge was Roman – to cross the Thames.

In Westminster the road is 'Knightsbridge' and 'Piccadilly'. In Hammersmith it is 'King Street', in Chiswick: the 'High Road', in Brentford and Kensington: 'High Street', and as Isleworth's 'London Road' passes into Hounslow it again becomes 'High Street'. After this the road united with the road to Maidenhead bridge (now mirrored by a nearby motorway bridge since the 1960s) this was part of the 'King's Highway' to Windsor.

1947 Rails-head Ferry still existed, more than fifty years after the nearby footbridge had been built.

Landmarks

Notable houses

thumb|Northumberland House and others in Lower Square in one of Isleworth's conservation areas

Much building of grand houses occurred in the 18th and 19th centuries.

Three allures to the eastern half of Isleworth and Twickenham by 1740s were felt, plus Richmond Bridge opened in 1776 (and to wheeled traffic a year later):

  1. The stretch of Thames with meadows, trees and broad water beauty figured in fine art, romantic verse by Alexander Pope.
  2. Grand houses already existed, attracting those in their very high social circles (several in Chiswick, plus Osterley Park House, Syon Park House, Boston Manor House and one of Prime Minister Walpole's houses in Twickenham).
  3. In the latter half of the Georgian era the royal court began to re-appear at Kew, so Kew and all adjacent parishes became, as under Elizabeth I, very fashionable for the rich and famous to build their grand homes.

Thanks to the 1840s mainstay of railway building, direct central London connections came, for the now royally deserted Richmond and Kew &ndash; prompting in most cases rebuilding or reinvestment in existing examples. Many high-quality houses also survived well The Blitz and need for wealthy or high income owners to afford their upkeep. Many thus have grade II* listing (the mid category) of architectural listed building.

  • Syon House&nbsp;Duke of Somerset&nbsp;Duke of Northumberland. (standing, listed Grade I) With parts 450 years old, it has very grand architecture as the only non-royal ducal main home ('seat') in Middlesex. It is chronicled in an exhaustive history.
