West Sussex

The county has a land area of km2 and an estimated population of 925,000 in 2026. The largest settlements are on the coast, and include the towns of Bognor Regis, Littlehampton, and Worthing; the last two are part of the Brighton and Hove built-up area, which extends into East Sussex. The interior of the county is generally rural, and contains the towns of Crawley and Horsham in the north-east and the city of Chichester in the south-west. For local government purposes West Sussex is a non-metropolitan county with seven districts. Sussex and East Sussex were historically a single county, Sussex. The South Downs are a defining feature of the county, crossing it from east to west and dividing the north and south. The downs are a chalk escarpment which falls away sharply into the Weald to the north and more gently toward the south, where there is a narrow strip of flat land between the hills and the coast. The coastal strip widens to the west, where it is punctuated by Chichester Harbour, a ria. The county has a long history of human settlement dating back to the Lower Paleolithic era. During the Roman conquest of Britain, Romans conquered the Atrebates, West Sussex's indigenous Britons, and incorporated the area as a Roman province. During the Early Middle Ages, the Saxons settled the area, establishing the Kingdom of Sussex in 477, which lasted until c. 827 when the kingdom was annexed by Wessex. It is home to Gatwick Airport, the UK's the second-busiest airport by total passenger traffic. The county has a number of stately homes including Goodwood, Petworth House and Uppark, and castles such as Arundel Castle and Bramber Castle.

• Official Name — West Sussex

The name Sussex, derived from the Old English 'Sūþseaxe' ('South Saxons'), dates from the Saxon period between AD 477 to 1066, and the history of human habitation in Sussex goes back to the Old Stone Age. The oldest hominin remains known in Britain were found at Eartham Pit, Boxgrove. Prehistoric monuments include the Devil's Jumps, a group of Bronze Age burial mounds, and the Iron Age Cissbury Ring and Chanctonbury Ring hill forts on the South Downs. The Roman period saw the building of Fishbourne Roman Palace and rural villas such as Bignor Roman Villa together with a network of roads including Stane Street, the Chichester to Silchester Way and the Sussex Greensand Way. The Romans used the Weald for iron production on an industrial scale. The foundation of the Kingdom of Sussex is recorded by the Anglo-Saxon Chronicle for the year AD 477; it says that Ælle arrived at a place called Cymenshore in three ships with his three sons and killed or put to flight the local inhabitants. The foundation story is regarded as somewhat of a myth by most historians, although the archaeology suggests that Saxons did start to settle in the area in the late 5th century. The Kingdom of Sussex was absorbed into Wessex as an earldom and became the county of Sussex. With its origins in the kingdom of Sussex, the later county of Sussex was traditionally divided into six units known as rapes. By the 16th century, the three western rapes were grouped together informally, having their own separate Quarter Sessions. These were governed by a separate county council from 1888, the county of Sussex being divided into the administrative counties of East and West Sussex. In 1974, West Sussex was made a single ceremonial county with the coming into force of the Local Government Act 1972. At the same time a large part of the eastern rape of Lewes (the Mid Sussex district which includes the towns of Haywards Heath, Burgess Hill and East Grinstead) was transferred into West Sussex. Until 1834, provision for the poor and destitute in West Sussex was made at parish level. From 1835 until 1948 eleven Poor Law Unions, each catering for several parishes, took on the job.

• Illustration — Chichester Market Cross Most settlements in West Sussex are either along the south coast or in Mid Sussex, near the Brighton Main Line and M23/A23 corridor. The town of Crawley is the largest in the county with an estimated population of 106,600. The coastal settlement of Worthing closely follows with a population of 104,600. The seaside resort of Bognor Regis and the market town of Horsham are both large towns. Chichester, the county town, has a cathedral and city status, and is situated not far from the border with Hampshire. Other conurbations of a similar size are Burgess Hill, East Grinstead and Haywards Heath in the Mid Sussex district, Littlehampton in the Arun district, and Lancing, Southwick and Shoreham in the Adur district. Much of the coastal town population is part of the Brighton/Worthing/Littlehampton conurbation. Rustington and Southwater are the next largest settlements in the county. There are several more towns in West Sussex, including Arundel, Midhurst, Petworth, Selsey, Steyning, Henfield, Pulborough and Storrington. Other notable villages include Billingshurst, Copthorne, Crawley Down, Cuckfield, Hassocks, Hurstpierpoint and Lindfield.

• Illustration — General map of West Sussex. West Sussex is bordered by Hampshire to the west, Surrey to the north and East Sussex to the east. The English Channel lies to the south. The area has been formed from Upper Jurassic and Lower Cretaceous rock strata, part of the Weald–Artois Anticline. The eastern part of this ridge, the Weald of Kent, Sussex and Surrey has been greatly eroded, with the chalk surface removed to expose older Lower Cretaceous rocks of the Wealden Group. In West Sussex the exposed rock becomes older towards the north of the county with Lower Greensand ridges along the border with Surrey including the highest point of the county at Blackdown. Erosion of softer sand and clay strata has hollowed out the basin of the Weald leaving a north facing scarp slope of the chalk which runs east and west across the whole county, broken only by the valleys of the River Arun and River Adur. In addition to these two rivers which drain most of the county a winterbourne, the River Lavant, flows intermittently from springs on the dip slope of the chalk downs north of Chichester. Some intermittent streams are known in the local dialect as "rifes". The county makes up 1.52% of the total land of England, making it the 30th largest county in the country. Bognor Regis

West Sussex is the sunniest county in the United Kingdom, according to Met Office records. Over the 29 years to 2011 it averaged 1902 hours of sunshine per year. Sunshine totals are highest near the coast with Bognor Regis often having the highest in mainland England, including a total of 2237 hours in 1990. Mean annual temperature for southern coastal counties is around 11 °C. The coldest month, January, has mean daily minimum temperatures of around 3 °C near the coast and lower inland. July tends to be the warmest month when mean daily maxima tend to be around 20 °C. A maximum temperature of 35.8 °C occurred at Wiggonholt on 24th June 2026. Coastal high temperatures are often moderated by cooler sea breezes. Monthly rainfall tends to be highest in autumn and early winter and lowest in the summer months, with July often being the driest month. There is less rainfall from summer convective showers and thunderstorms than in inland areas. The county can suffer both from localised flooding caused by heavy rainfall and from water shortages caused by prolonged periods of below average rainfall. Winter rainfall is needed to recharge the chalk aquifers from which much of the water supply is drawn.

The M23 motorway runs from London to the south of Crawley. The A23 and A24 roads run from London to Brighton and Worthing respectively with the A29 a little further west ending in Bognor Regis. Other major roads are the A272 which runs east to west through the middle of the county and the A27 which does the same but closer to the coast. The A259 is a local alternate route to the A27 in the eastern coastal strip. Gatwick Airport, which handled over 33 million passengers and had over 250,000 aircraft movements in 2011, is located within the borders of Crawley, and is the second largest airport in the United Kingdom. There is also a considerably smaller local airport at Shoreham Airport and a grass airfield handling light aircraft and helicopters at Chichester/Goodwood Airport. There are three main railway routes: the Brighton Main Line, the Arun Valley line and the West Coastway line. The Portsmouth Direct line serves and occasionally enters the westernmost part of West Sussex, although it has no railway stations in the county.

The Cathedral Church of the Holy Trinity, otherwise called Chichester Cathedral, is the seat of the Anglican Bishop of Chichester. It was founded as a cathedral in 1075, when the seat of the bishop was moved from Selsey Abbey. The cathedral has architecture in both the Norman and the Gothic styles, and has been called by the architectural historian Nikolaus Pevsner "the most typical English Cathedral". The Cathedral Church of Our Lady and St Philip Howard in Arundel is the Roman Catholic cathedral of the Diocese of Arundel and Brighton. Built in French Gothic style and dedicated in 1873 as the Catholic parish church of Arundel, it was not designated a cathedral until the foundation of the diocese in 1965. Bosham Church is partly of Saxon construction and is shown on the Bayeux Tapestry as the local church of late Saxon and Danish kings of England. Many other Saxon and early Norman churches have survived in the county with little alteration including the Church of St Mary the Blessed Virgin, Sompting, an 11th-century Anglo-Saxon church with a Rhenish helm unique in England and St. Nicholas Church, Worth, a 10th-century church in Worth, Crawley. Some Anglican churches and many of the numerous nonconformist chapels in the county have been converted to residential use. Cittaviveka is a Buddhist monastery in Chithurst.

West Sussex developed distinctive land uses along with its neighbours in the weald. The Landrace cattle transformed into Sussex cattle and Sussex chickens emerged about the time of the Roman conquest. Some of the earliest evidence of horses in Britain has been found at Boxgrove, dated to 500,000 BC. Viticulture is a part of the economy, with wineries producing mainly sparkling wine of varied quality.
