Abingdon-on-Thames ( ), commonly known as Abingdon, is a historic market town and civil parish on the River Thames in the Vale of the White Horse district of Oxfordshire, England. The historic county town of Berkshire, the area was occupied from the early to middle Iron Age and the remains of a late Iron Age and Roman defensive enclosure lies below the town centre. Abingdon Abbey was founded around 676 AD, giving its name to the emerging town. In the 13th and 14th centuries, Abingdon was an agricultural centre with an extensive trade in wool, alongside weaving and the manufacture of clothing. Charters for the holding of markets and fairs were granted by various monarchs, from Edward I to George II.

The town survived the dissolution of the abbey in 1538 and by the 18th and 19th centuries, with the building of Abingdon Lock in 1790 and the Wilts & Berks Canal in 1810, Abingdon was on important routes for goods transport. In 1856 the Abingdon Railway opened, linking the town with the Great Western Railway. The canal was abandoned in 1906 but a voluntary trust is now working to restore and reopen it. Abingdon railway station was closed to passengers in September 1963. The line remained open for goods until 1984, its role including serving the MG car factory, which operated from 1929 to 1980.

Abingdon's brewery, Morland, makers of Old Speckled Hen ale, was taken over and closed in 1999; the site of the brewery has been redeveloped into housing. The rock band Radiohead formed in 1985 when its members were studying at Abingdon School, a day and boarding independent secondary school. The 2011 census recorded the parish's population as 33,130.

History

A Neolithic stone hand axe was found at Abingdon. Petrological analysis in 1940 identified the stone as epidotised tuff from Stake Pass in the Lake District, to the north. Stone axes from the same source have been found at Sutton Courtenay, Alvescot, Kencot and Minster Lovell. Abingdon has been occupied from the early to middle Iron Age and the remains of a late Iron Age defensive enclosure (or oppidum) lies below the town centre. The oppidum was in use throughout the Roman occupation. A Neolithic causewayed enclosure was found in Abingdon, dating to the 36th or 37th century BC. It was found in 1926 while quarrying for gravel, and was partly excavated in 1926 and 1927 by E.T. Leeds. Subsequent excavations took place in 1954 and 1963.Healy et al. (2011), pp. 407-420. A Roman villa and subsequent Saxon farmstead buildings have been excavated at Barton Court Farm.

Abingdon Abbey was founded in Saxon times, possibly around 676, but its early history is confused by numerous legends, invented to raise its status and explain the place name. The name seems to mean 'Hill of a man named Æbba, or a woman named Æbbe', possibly the saint to whom St Ebbe's Church in Oxford was dedicated (Æbbe of Coldingham or a different Æbbe of Oxford). However, Abingdon stands in a valley and not on a hill. It is thought that the name was first given to a place on Boars Hill above Chilswell, and the name was transferred to its present site when the Abbey was moved. In 1084, William the Conqueror celebrated Easter at the Abbey and it is possible that his son Henry I received some schooling at the abbey.

In the 13th and 14th centuries, Abingdon was a flourishing agricultural centre with an extensive trade in wool and a famous weaving and clothing manufacturing industry. The abbot seems to have held a market from very early times and charters for the holding of markets and fairs were granted by various sovereigns, from Edward I to George II. In 1337 there was a famous riot in protest at the Abbot's control of this market in which several of the monks were killed. After the abbey's dissolution in 1538, the town sank into decay.

In 1556, upon receiving a representation of its pitiable condition, Mary I granted a charter incorporating the town as a borough, governed by a mayor, two bailiffs, twelve chief burgesses and sixteen secondary burgesses, the mayor to be clerk of the market, coroner and a JP. The present Christ's Hospital originally belonged to the Guild of the Holy Cross, on the dissolution of which Edward VI founded the almshouses instead, under its present name.

The borough elected one member of parliament; this right would continue until the Redistribution of Seats Act 1885. The 1556 charter also catered for the appointment of a town clerk and other officers, and the borough boundaries were described in detail. Later charters, from Elizabeth I, James I, James II, George II and George III, made no considerable change. James II changed the style of the corporation to that of a mayor, twelve aldermen and twelve burgesses.

Abingdon became the county town of Berkshire sometime after receiving its charter in 1556. Assize courts were held in Abingdon from 1570, but in the 17th century it was vying with Reading for county town status. The county hall and court house were built between 1678 and 1682, to assert this status. The building, now the Abingdon County Hall Museum, was reputedly designed by Christopher Kempster, who worked with Sir Christopher Wren.

Abingdon borough police was the police force responsible for policing the Borough until 1889. It was formed as a result of the Municipal Corporations Act 1835. The force was amalgamated into the Berkshire Constabulary following the Local Government Act 1888, which required all boroughs with populations of less than 10,000 to amalgamate their police forces with their adjoining county constabulary. Today, the area is policed by the successor to Berkshire Constabulary, Thames Valley Police.

In 1790 Abingdon Lock was built, replacing navigation via the Swift Ditch. In 1810, the Wilts & Berks Canal opened, linking Abingdon with Semington on the Kennet and Avon Canal. Abingdon became a key link between major industrial centres such as Bristol, London, Birmingham and the Black Country. In 1856 the Abingdon Railway opened, linking the town with the Great Western Railway at . However, Abingdon's failure to engage fully with the railway revolution, accepting only a branch line, sidelined the town in favour of Reading which became the County Town in 1869.

The Wilts & Berks Canal was abandoned in 1906 but a voluntary trust is now working to restore and re-open it. Abingdon railway station was closed to passengers in September 1963. The line remained open for goods until 1984, including serving the MG car factory, which opened in 1929 and closed in October 1980 as part of a British Leyland rationalisation plan. The nearest railway station is , away. Much of the original Abingdon branch line is now a cycle path, whilst the land on which the station stood has been extensively redeveloped, and is now the site of a large Waitrose store and surrounded by a large number of new flats and houses.

The corporation was reformed, under the Municipal Corporations Act 1835, but was abolished under the Local Government Act 1972, which enacted extensive local government reorganisation across England and Wales with effect from 1 April 1974. As a result of this reorganisation, Berkshire County Council's northern boundary was much reduced and Abingdon's governance was transferred to Oxfordshire, with the town becoming the seat of the new Vale of White Horse District Council, and Abingdon becoming a civil parish with a town council. Since the 1980s, Abingdon has played host to a number of information communication companies, with many based in the town's respective business and science parks. As a consequence, and owing to Abingdon's proximity to academic and scientific institutions in Oxford, the town has seen an influx of young professionals taking residence in the town's many residential areas such as Peachcroft.

The town was sometimes historically called "Abingdon-on-Thames", but the official name of the borough (as given in statutes from the Municipal Corporations Act 1835 to the Local Government Act 1972 and all intervening Ordnance Survey maps) was simply "Abingdon". Local councillors voted in November 2011 to change the official name of the town to "Abingdon-on-Thames", and the change took effect on 23 February 2012.

Leisure and media Sport and recreation facilities include the White Horse Leisure and Tennis Centre, Tilsley Park and the Southern Town Park. Abingdon had four cinemas but all have closed. The last was the Regal, which closed in 1989. It stood derelict for 24 years until it was demolished in 2003 and replaced by housing development, Regal Close. The Unicorn theatre was built in an area called The Checkers Hall in the ruins of the Abbey buildings and shows plays and films on an irregular basis. In addition, a new cinema, called the Abbey Cinema has been built in one of the town council buildings and operates in conjunction with the Regal in Evesham.

The local newspapers are The Oxford Times, Oxford Mail and Abingdon Herald. The Oxfordshire Guardian, a free newspaper, was based in Abingdon for many years and was founded as the South Oxfordshire Courier until its closure in 2018. Local radio and television stations are shared with Oxford, although ITV retains a news gathering centre in nearby Milton Park (formerly having a broadcasting studio in the town) for ITV Meridian. Historically the ITV franchise was ITV Central. Local analogue radio is provided by BBC Radio Oxford, Greatest Hits Radio and Heart South (historically 'Fox FM' and later 'Heart Thames Valley'), while the town is also covered by the Oxfordshire DAB multiplex. There was a Six TV local TV channel until 2009 and the town's further education college was the home to That's TV studios for Oxfordshire until it relocated to Oxford Science Park.

The Tesco Extra store west of the town is the largest supermarket in Abingdon and has historically been one of the most profitable Tesco stores in the country. Nearby is the Fairacres Retail Park, thought to be the first retail park in the UK and recently redeveloped, which includes Argos, Subway, B & M, Dreams and Pets at Home stores. It originally had two long established Abingdon retailers—Vineys Home Furnishings (now part of the Lee Longlands chain but retains its name) and Mays Carpets (now part of the Carpetright chain and has re-branded accordingly). In the town centre, many independent stores, estate agents and charity shops make up the Bury Street shopping centre as major high street names have chosen to go to other towns.

The town centre of Abingdon was renovated in 2012 as part of the council's redevelopment plan, with the 1970s shopping precinct converted to look more modern. The roads around the area have been changed: notably the one-way system around the centre has been partially changed to two-way. While this has slightly reduced traffic within the historic town centre, congestion has greatly increased elsewhere. Local businesses have also complained that the increased traffic has driven shoppers away. Redevelopment of the Old Gaol site, most recently a leisure centre, began in 2010. The first stage was demolishing the 1970s additions and swimming pool extension. The Gaol has been converted into luxury flats, shops and restaurants, with access to the riverside.
