The town's name was first recorded in 1195 as
Slo. It first seems to have applied to a hamlet between
Upton to the east and
Chalvey to the west, roughly around the "Crown Crossroads" where the road to Windsor (now the A332) met the Great West Road. The
Domesday Survey of 1086 refers to Upton, and a wood for 200 pigs, worth £15. During the 13th century, King
Henry III had a palace at Cippenham. Parts of Upton Court were built in 1325. St Mary the Virgin Church in
Langley was probably built in the late 11th or early 12th century, though it has been rebuilt and enlarged several times. From the mid-17th century,
stagecoaches passed through Slough and
Salt Hill, later absorbed into Slough, as locations to change horses on the journey out from London. By 1838 and the opening of the
Great Western Railway, Upton-cum-Chalvey's parish
population was 1,502. In 1849, a
branch line was completed from
Slough to
Windsor & Eton Central, opposite
Windsor Castle, for
Queen Victoria's convenience. Slough has 96
listed buildings, i.e. protected historic structures. There are •
Four Grade I:
St Laurence's Church (Upton),
St Mary the Virgin Church, Langley, Spectacular growth and employment ensued, with Slough attracting workers from many parts of the UK and abroad.
Slough Town Hall, which was designed by
Charles Holloway James and
Stephen Rowland Pierce, was completed in 1937. During the
Second World War, Slough experienced a series of
air raids, mostly in October 1940. On the 13th, 5 people were killed in an air raid, the deadliest raid on Slough. An emergency hospital treating casualties from London was set up in Slough. Local air raid deaths and deaths at the hospital account for the 23 civilian lives lost in the borough area. After the war, several further large housing developments arose to take large numbers of people migrating from war-damaged London. Between 1955 and 1957 the town was the site of the
Slough experiment, a large-scale road safety trial. The old Slough library opened in November 1974, named after Alderman Robert Taylor in recognition of his contribution to the library service. The library was officially opened by the Mayor, Councillor DR Peters, in May 1975. It was demolished in May 2017 as part of the programme of redevelopment in the town centre.
Redevelopment : Council's headquarters 1937–2011, now a school In the 21st century, Slough has seen major redevelopment of the town centre. Old buildings are being replaced with new offices and shopping complexes.
Tesco has replaced an existing superstore with a larger
Tesco Extra. The
Heart of Slough Project is plan for the large-scale redevelopment of the town centre as a focus and cultural quarter for the creative media, information and communications industries created a mixed-use complex, multi-functional buildings, visual landmarks and a public space in the
Thames Valley. Approval was given for the £400 million project by Slough Borough Council's planning committee in July 2009, and work began in 2010 for completion in 2018. In December 2009, two key components of the project were signed: the Homes and Communities Agency (HCA) signed its agreement to provide £11m of funding for infrastructure and Thames Valley University (TVU) courses which were due to remain in the town found a new home at the Centre in Farnham Road, Slough. In parallel to the town centre redevelopment plan,
Segro, owner of the Slough Trading Estate, planned to spend £600 million over the following 20 years on the estate. This was intended to create environmentally sustainable buildings, open green spaces, two hotels, a conference centre, cafés, restaurants and better transport facilities to improve links to Slough town centre and the surrounding residential areas. It was claimed that the plan would create more than 4,100 new jobs and contribute around £100m a year to Slough's economy. If both plans went ahead, nearly £1 billion would be spent on redeveloping Slough over the next 20 years. In 2009,
Herschel Park, known as Upton Park until 1949, named for
astronomer William Herschel, was relandscaped in a multimillion-pound effort to bring it back to its former
Victorian era glory. The park was featured in an episode of the documentary programme
Who Do You Think You Are? focusing on the TV presenter
Davina McCall. In 2010, £2 million was set aside to improve disabled access to Slough railway station in preparation for an expected increase in use during the 2012 London Olympics. Preparations were under way for the regeneration of the Britwell suburb of Slough, involving tearing down a dilapidated block of flats and the closing of the public house the Jolly Londoner in Wentworth Avenue and replacing them with new homes, as well as relocating the shopping parade in the street to nearby Kennedy Park. As part of the Heart of Slough project, construction work on
a new bus station began in March 2010, following weeks of demolition work to half of the existing bus station and the removal of Compair House near the railway station. It was opened in May 2011. Redevelopment on this scale has been strongly criticised by conservation groups.
The Twentieth Century Society has stated that [A] tragically high quantity of good buildings have been demolished in Slough in recent years, including grand Art-Deco-styled factories by the likes of Wallis Gilbert and high-quality post-war offices. More are to come down as the town tries to erase its past and reinvent itself from scratch. Despite famously heckling Slough,
John Betjeman's praise for the town hall's architecture as 'a striving for unity out of chaos' in 1948 has never been so relevant as today. C20 believes that the redevelopment of the town hall would be an act of vandalism to the civic centre and is supporting the Campaign to Save Slough's Heritage in their request for a review of the decision. During November 2016, the Slough Queensmere and Observatory shopping centres were sold to
Abu Dhabi Investment Authority (ADIA) in a deal worth £130 million. In February 2025, it was reported that the council was considering a number of options to merge with larger local authorities, including joining a London borough or becoming part of the
Greater London Authority. ==Geography==
