Prehistoric and Roman artefacts have been found in the area, at the site of the Gatcombe Roman Settlement, but the village originated in Saxon times. The Domesday Book records it as Estune (the place by the ash tree) and, afterwards, it was granted to Bishop Geoffrey of Constances. The village was normally just called Ashton up to the mid 19th century. It acquired the prefix "Long" from the fact that it straggles along the main road for nearly 2 miles.
The parish was part of the hundred of Hartcliffe.
The manor house dates to 1265 and, in the late 15th century shares in the estate were purchased by Richard Amerike (one of the possible sources of the name America). Previously the manor had passed through the hands of the Lyons, Choke and finally Smyth families. By 1603 the Smyths had become the principal landowners in the parish and were lords of Long Ashton for four centuries—the estate finally being sold in 1946. A deserted medieval farmstead and part of a Romano-British field system 400 metres (1,300 ft) north of Fenswood Farm has been identified including three enclosures which are thought to be the foundations of buildings, each surrounded by a rubble banks.
The parish church of All Saints dates from about 1380, and the arms of its founder (Thomas de Lyons) are on the outside of the tower. The interior has some fine tombs, and some relatives of the poet Robert Southey are buried in the churchyard.
The other Church, Hebron Church was founded in 1934 by Ernest Dyer, who cycled to the village from Keynsham to run a Sunday School. Many of the people who have grown up in the village passed through this Sunday School.
Since the earliest recorded times, agriculture has been the major occupation of the parish, and there are still several working farms, some just outside the village. The Ashton Court estate provided occupations such as gamekeepers and foresters, and there have been several mills in the parish including a snuff-mill on the Land Yeo at Gatcombe in 1769, however the current building dates from the early 19th century. By 1846 it had been converted to grind mustard, annatto and drugs, but by 1874 was a flour mill. The internal machinery is still in place and the mill has been designated as a Grade II listed building. Kincott Mill had stood since at least the 13th century. By the early 19th century rented out for snuff grinding and in the 1830s a steam engine was installed to power a flour and corn mill. Later it was owned by an iron founder, who made edge tools and other farm implements and installed cast-iron water wheels.
Stone has been quarried for lime burning, as well as for building and road making. There was an iron foundry in the 19th century and coal mines — the Bedminster-Ashton coalfield finally closed in 1924.
The Angel Inn, near the church, is the oldest pub in the village, dating from 1495 and originally being a church-house. There are several other historic pubs in the area, very popular with visitors from Bristol—a horse-drawn bus ran from Redcliffe Street, Bristol to the Bird-in-Hand several times a week in the late 19th century.
The National Fruit and Cider Institute opened at Fenswood on the edge of the village in 1903. It became the Agricultural and Horticultural Research Station in 1912, and was known as Long Ashton Research Station until it was closed in 2003. During the Second World War it developed rose hip syrup and Ribena.
A Parochial School opened in 1818 and moved several times — the current Primary School, called Northleaze, opened in 1867 and moved to new premises in Brook Close in 2006. There have been other schools in the village, including boarding schools for "Young Gentlemen".
Long Ashton railway station was opened by the Great Western Railway in Yanley Lane, where the Bristol to Taunton Line passes below the village, on 12 July 1926 but it was closed on 6 October 1941.
The parish council has responsibility for local issues, including setting an annual precept (local rate) to cover the council's operating costs and producing annual accounts for public scrutiny. The parish council evaluates local planning applications and works with the local police, district council officers, and neighbourhood watch groups on matters of crime, security, and traffic. The parish council's role also includes initiating projects for the maintenance and repair of parish facilities, such as the village hall or community centre, playing fields and playgrounds, as well as consulting with the district council on the maintenance, repair, and improvement of highways, drainage, footpaths, public transport, and street cleaning. Conservation matters (including trees and listed buildings) and environmental issues are also of interest to the council.
The parish falls within the unitary authority of North Somerset which was created in 1996, as established by the Local Government Act 1992. It provides a single tier of local government with responsibility for almost all local government functions within their area including local planning and building control, local roads, council housing, environmental health, markets and fairs, refuse collection, recycling, cemeteries, crematoria, leisure services, parks, and tourism. They are also responsible for education, social services, libraries, main roads, public transport, Trading Standards, waste disposal and strategic planning, although fire, police and ambulance services are provided jointly with other authorities through the Avon Fire and Rescue Service, Avon and Somerset Constabulary and the Great Western Ambulance Service.
North Somerset's area covers part of the ceremonial county of Somerset but it is administered independently of the non-metropolitan county. Its administrative headquarters are in the town hall in Weston-super-Mare. Between 1 April 1974 and 1 April 1996, it was the Woodspring district of the county of Avon. Before 1974 that the parish was part of the Long Ashton Rural District.
The village falls within the 'Wraxall and Long Ashton' electoral ward. The ward starts in the west at Wraxall and proceeds easterly to Long Ashton. The total population of the ward as at the 2011 census was 7,793.
The parish is represented in the House of Commons of the Parliament of the United Kingdom as part of the Woodspring county constituency which is to become North Somerset at next general election. It elects one Member of Parliament (MP) by the first past the post system of election. It is also part of the South West England constituency of the European Parliament which elects seven MEPs using the d'Hondt method of party-list proportional representation.
Long Ashton Cricket Club plays in Yanley Lane. It runs two Saturday sides as well as a number of junior teams. The team won the Bristol & District Cricket Association League in 1977.
Famous players have included Chris Broad, who went on to become international cricketer of the year. Shane Warne, who was named as one of the five cricketers of the 20th century, played a few games for Long Ashton on tour in Cornwall in the early 1980s.
Leigh Woods has been built on since 1865, and the land south of Nightingale Valley was fully developed by 1909. The rest has been preserved by gifts of land by the Wills family and is now owned by the National Trust.
The Clifton Suspension Bridge was opened in 1864 and provided an alternative route to Bristol; in 1906, a swing bridge was opened to give access to Hotwells. Traffic continued to grow throughout the 20th century, and a bypass was opened in 1968.
Ashton Court is a large estate that lies at the east end of the village. It was originally owned by the Smyth family until they were forced to donate it to Bristol City Council in lieu of inheritance tax. Ashton Court is host to several festivals each year, including the Bristol International Balloon Fiesta and the scenic landscaped grounds with views of Bristol are widely used by local residents for walking, golf and mountain biking.
Dawsons walk is an area of green space donated to the people of Long Ashton. It has been developed into a circular woodland and countryside walk. Access to the walk is from Lampton Road or from public footpath between Bourton Mead and 40 Long Ashton Road.
The Long Ashton Footpath Users Group have replaced 29 stiles on the public rights of way around the village with kissing gates to create a complete circular walk around the village, accessible to older people and those with mobility problems, although it can be muddy in places. The route, way marked with yellow Village Circular Walk discs, takes in views of the valley, passing through local farms and woodland.Ferdinando Gorges (1565-1647) Had legal ownership of coastal Maine, the U.S. State.
