South Downs National Park in the context of "Arun District"

Worthing (/ˈwɜːrðɪŋ/ WUR-dhing) is a seaside town and borough in West Sussex, England, at the foot of the South Downs, 11 miles (18 km) west of Brighton, and 18 miles (29 km) east of Chichester. With a population of 113,094 and an area of 12.5 square miles (32.4 km), the borough is the second largest component of the Brighton and Hove built-up area, the 15th most populous urban area in the United Kingdom. Northern parts of the borough, including the Worthing Downland Estate, form part of the South Downs National Park. In 2019, the Art Deco Worthing Pier was dubbed the best in Britain.

Dating from around 4000 BC, the flint mines at Cissbury and nearby Church Hill, Blackpatch and Harrow Hill are amongst the earliest Neolithic monuments in Britain. The Iron Age hill fort of Cissbury Ring is one of Britain's largest. The recorded history of Worthing began with the Domesday Book. Worthing is historically part of Sussex, mostly in the rape of Bramber; Goring, which forms part of the rape of Arundel, was incorporated in 1929. Worthing was a small mackerel fishing hamlet for many centuries until, in the late 18th century, it developed into an elegant Georgian seaside resort and attracted the well-known and wealthy of the day. In the 19th and 20th centuries, the area was one of Britain's chief market gardening centres.

Sussex (/ˈsʌsɪks/; from the Old English Sūþseaxe; lit. 'South Saxons'; 'Sussex') is an area of South East England that was historically a kingdom and, later, a county. The current ceremonial counties of East Sussex and West Sussex cover approximately the same area. The two ceremonial counties border Surrey to the north, Kent to the north-east, the English Channel to the south, and Hampshire to the west. Sussex contains the city of Brighton and Hove and its wider city region, part of the South Downs National Park and the national landscape of the High Weald, and Chichester Harbour. Its coastline is 137 miles (220 km) long.

The Kingdom of Sussex emerged in the fifth century in the area that had previously been inhabited by the Regni tribe in the Romano-British period. In about 827, shortly after the Battle of Ellendun, Sussex was conquered by Wessex. From 860 it was ruled by the kings of Wessex, and in 927 it became part of the Kingdom of England. By the Norman period, Sussex was subdivided into six administrative districts known as rapes, which were themselves divided into hundreds. By the sixteenth century, the eastern three rapes and the western three rapes had been combined for most meetings of the court of quarter sessions, a division which was reinforced when the administrative counties of East Sussex and West Sussex were established in 1889. Subsequent local government reforms maintained the division into east and west. The county retained a single lord lieutenant and sheriff until 1974, when they were replaced with separate posts for East and West Sussex and Sussex lost its status as a ceremonial county.

The University of Sussex is a public research university located in Falmer, East Sussex, England. It lies mostly within the city boundaries of Brighton and Hove. Its large campus site is surrounded by the South Downs National Park, and provides convenient access to central Brighton 5.5 kilometres (3+1⁄2 miles) away. The university received its royal charter in August 1961, the first of what later was called the plate glass university generation.

More than a third of its students are enrolled in postgraduate programmes and approximately a third of staff are from outside the United Kingdom. Sussex has a diverse community of nearly 20,000 students, with around one in three being foreign students, and over 1,000 academics, representing over 140 different nationalities. The annual income of the institution for 2023–24 was £379.6 million of which £39.9 million was from research grants and contracts, with an expenditure of £291.3 million.

The South Downs are a range of chalk hills that extends for about 260 sq mi (670 km) across the south-eastern coastal counties of England. This area of downland extends from the Itchen Valley of Hampshire in the west to Beachy Head, in the Eastbourne Downland Estate of East Sussex, in the east. The Downs are bounded on the northern side by a steep escarpment, from whose crest there are extensive views northwards across the Weald. The South Downs National Park forms a much larger area than the chalk range of the South Downs, and includes large parts of the Weald. The national park is the UK's most visited, attracting an estimated 39 million visitor-days annually.

The South Downs are characterised by rolling chalk downland with close-cropped turf and dry valleys, and are recognised as one of the most important chalk landscapes in England. The range is one of the four main areas of chalk downland in southern England.

Bishop's Waltham (or Bishops Waltham) is a medieval market town situated at the source of the River Hamble in Hampshire, England. It has a foot in the South Downs National Park and is located at the midpoint of a long-established route between Winchester and Portsmouth. It is home to the ruins of Bishop's Waltham Palace, a Scheduled Ancient Monument under English Heritage management, and a well-preserved high street with many listed buildings which now house independent shops.

Bishop's Waltham's long history includes a roll call of Medieval and Tudor kings and queens who visited the town to stay at the palace. The name of the town is derived from the Anglo-Saxon words: "wald" (forest) and "ham" (settlement).

The Worthing Downland Estate, Worthing Downs or Worthing Downland, is an area of land in the South Downs National Park in West Sussex, England, close to the town of Worthing.
