East Sussex is a ceremonial county in South East England. It is bordered by Kent to the north-east, West Sussex to the west, Surrey to the north-west, and the English Channel to the south. The largest settlement is the city of Brighton and Hove.
The county has an area of and had an estimated population of in . The largest settlements are on the coast, and include Brighton and Hove in the south-west, Eastbourne in the south, and Hastings in the south-east. Away from the coast the county is largely rural, and its settlements include Crowborough in the north, Hailsham in the south-centre, and Lewes in the west. For local government purposes East Sussex comprises a non-metropolitan county, with five districts, and the unitary authority of Brighton and Hove. East Sussex and West Sussex historically formed a single county, Sussex.
The north east of East Sussex is part of the Weald, a sandstone anticline that was once an extensive woodland. The highest point in this area is Crowborough Hill (), part of the High Weald uplands. The south west of the county is part of the South Downs, a rolling chalk escarpment that stretches west into West Sussex and Hampshire. Ditchling Beacon () is the highest point. Where the downs reach the sea, they form high cliffs such as the Seven Sisters, where eroded dry valleys create an undulating skyline. The county does not contain large rivers, but its largest are the Rother, which forms part of the boundary with Kent, the Cuckmere, and the Ouse, which rises in West Sussex and flows through Lewes before reaching the English Channel at Newhaven.
History
East Sussex is part of the historic county of Sussex, which has its roots in the ancient kingdom of the South Saxons, who established themselves there in the 5th century AD, after the departure of the Romans. Archaeological remains are plentiful, especially in the upland areas. The area's position on the coast has also meant that there were many invaders, including the Romans and later the Normans, following the defeat of the English army by William the Conqueror at the Battle of Hastings in 1066. Earlier industries included fishing, iron-making, and the wool trade, all of which have declined or been lost completely.
Governance
Sussex was historically sub-divided into six rapes. From the 12th century the three eastern rapes together and the three western rapes together had separate quarter sessions, with the county town of the three eastern rapes being Lewes. This situation was formalised by Parliament in 1865, and the two parts were made into administrative counties, each with its own elected county council in 1889 under the Local Government Act 1888. In East Sussex there were also three self-administered county boroughs: Brighton, Eastbourne and Hastings.
Upon its foundation, East Sussex included the south of Tunbridge Wells and the south of Lamberhurst; by the Local Government Act 1894 these areas were transferred to Kent.
In 1974 East Sussex was made a non-metropolitan and ceremonial county, and the three county boroughs became districts within the county. At the same time the western boundary was altered, so that the Mid Sussex region (including Burgess Hill and Haywards Heath) was transferred to the non metropolitan county of West Sussex. In 1997, Brighton and Hove became a self-administered unitary authority; it was granted city status in 2000, whilst remaining part of the ceremonial county of East Sussex.
The area of East Sussex County Council's jurisdiction is divided into five local government districts. Three are large rural districts (from west to east): Lewes, Wealden, and Rother. Eastbourne and Hastings are mainly urban areas. The rural districts are further subdivided into civil parishes.See List of civil parishes in East Sussex
For parliamentary purposes, East Sussex (including Brighton and Hove) is divided into nine Westminster constituencies, returning nine Members of Parliament. The current boundaries were established by the Boundary Commission for England following its 2023 Periodic Review of Westminster constituencies and came into effect at the 2024 general election.
Future In July 2026, the UK Government announced its intention to reorganise East Sussex into two unitary authority areas by April 2028. One will cover Brighton and Hove, with larger boundaries than the current district, and the other will cover the remainder of the county. Elections to the new authorities will take place in May 2027. In September 2026, this process was paused for review and local elections for West Sussex were reinstated for May 2027.
Geography
Geology
Geologically, East Sussex is part of southern anticline of the Weald: the South Downs, a range of moderate chalk hills which run across the southern part of the county from west to east and mirrored in Kent by the North Downs. To the north lie parallel valleys and ridges, the highest of which is the Weald itself (the Hastings beds and Wealden Clay). The sandstones and clays meet the sea at Hastings; the Downs, at Beachy Head. The area contains significant reserves of shale oil, totalling 4.4 billion barrels of oil in the Wealden basin according to a 2014 study, which then Business and Energy Minister Michael Fallon said "will bring jobs and business opportunities" and significantly help with UK energy self-sufficiency. Fracking in the area is required to achieve these objectives, which has been opposed by environmental groups.
Climate East Sussex, like most counties by the south coast, has an annual average total of around 1,750 hours of sunshine per year. This is much higher than the UK's average of about 1,340 hours of sunshine a year.
Relief and drainage The relief of the county reflects the geology.
The chalk uplands of the South Downs occupies the coastal strip between Brighton and Eastbourne. There are two river gaps: the Rivers Ouse and Cuckmere. The Seven Sisters, where the Downs meet the sea, are the remnants of dry valleys cut into the chalk; they end at Beachy Head, 530 feet (162 m) above sea level. To the east of Beachy Head lie the marshlands of the Pevensey Levels, formerly flooded by the sea but now enclosed within a deposited beach. At Bexhill the land begins to rise again where the sands and clays of the Weald meet the sea; these culminate in the sandstone cliffs east of Hastings. Further east are the Pett Levels, more marshland, beyond which is the estuary of the River Rother. On the far side of the estuary are the dunes of Camber Sands. The highest point in the county is Ditchling Beacon on the South Downs, which has a maximum elevation of and is classed as a Marilyn.
The Weald occupies the northern borderlands of the county. Between the Downs and Weald is a narrow stretch of lower lying land; many of the rivers and streams occupying this area originate in the Weald. The High Weald is heavily wooded in contrast to the South Downs; the Low Weald less so. Part of the Weald is the Ashdown Forest.
Settlements
The location of settlements in East Sussex has been determined both by its history and its geography. The original towns and villages tended to be where its economy lay: fishing along the coast and agriculture and iron mining on the Weald. Industry today tends to be geared towards tourism, particularly along the coastal strip where towns such as Bexhill-on-Sea, Eastbourne, and Hastings are located. Newhaven and Rye are ports, although the latter is also of historical importance. Peacehaven and Seaford serve as dormitory towns. Away from the coast are former market towns such as Hailsham, Heathfield and Uckfield; Crowborough is a centre for the Ashdown Forest. Lewes, the County town of East Sussex; Battle, with its Norman Conquest beginnings, and Wadhurst are the other three towns of significance.

Economic activities Measured by the number of registered companies, East Sussex is not a major manufacturing or industrial area of the United Kingdom. Of the companies registered, the leading category in 2023 was "construction", followed by "real estate activities". An important contribution to the county's economy comes from the fact that many residents of Brighton and Hove, Eastbourne and Hastings commute to London or work remotely for companies outside the county.
There were 1,720 agricultural holdings in East Sussex (excluding Brighton and Hove) in 2022, with a total farmed area of 108,825 hectares. They employed just over 4000 people and, in 2020, produced a gross value added of £66 million. Livestock grazing accounts for almost 40% of the farmed area, with there being approximately six times as many sheep as cattle. Fishing is limited but there are still fishing fleets, notably at Rye and Hastings, although the number of boats is much reduced. Historically, the fisheries were of great importance.
Landmarks
The Seven Sisters area forms part of the South Downs National Park. Other notable natural landmarks include Beachy Head and the low-lying coast around Normans Bay.
East Sussex also contains numerous historic landmarks. There are castles at Bodiam, Herstmonceux, Lewes and Pevensey; and defence works such as the Martello towers and Eastbourne Redoubt. Other notable sites include Battle Abbey, Bateman's, Hammerwood Park and the University of Sussex campus at Falmer. Bexhill-on-Sea is also home to the De La Warr Pavilion. East Sussex also includes two chalk hill figures, being the Litlington White Horse and the Long Man of Wilmington, which are both situated in the Sussex Downs.
Transport
Roads
East Sussex has no motorways, and even dual carriageways are sparse in the county. The main roads through the county are those part of the radial pattern from London: the A21 from Kent to Hastings; the A22 from Surrey to Eastbourne; and the A23 from Gatwick to Brighton. Cross-country routes include the A26 which carries traffic from Newhaven and Lewes north into Kent; and the south coast trunk route, which starts in Folkestone (Kent) as the A259 trunk road, and traverses the south coast to Eastbourne, where it becomes the A27 trunk road and heads westwards towards Chichester in West Sussex and ultimately to Honiton in Devon. The county's main roads suffer from congestion and traffic problems, particularly the A27, which connects Eastbourne with Portsmouth.
Bus routes serve all the main areas of settlement and many of the villages in the county.
Railways The railways serve the main towns in a similar fashion to the roads. Until the closures of many branch railways in the 20th century, rural East Sussex was well-served by rail: few such branch lines escaped the Beeching cuts so that today only main-line services remain. They include the East Coastway Line (including the Marshlink Line); the Hastings line; and the Uckfield branch of the Oxted Line. There are three heritage railways: the Kent and East Sussex Railway operates from Tenterden in Kent to Bodiam; the Bluebell Railway from Sheffield Park to East Grinstead; and the Lavender Line Steam Railway is a one-mile line at Isfield, near Uckfield.
