Neolithic British Isles in the context of "Sweet Track"

Stonehenge is a prehistoric megalithic structure on Salisbury Plain in Wiltshire, England, two miles (3 km) west of Amesbury. It consists of an outer ring of vertical sarsen standing stones, each around 13 feet (4.0 m) high, seven feet (2.1 m) wide, and weighing around 25 tons, topped by connecting horizontal lintel stones which are held in place with mortise and tenon joints—a feature unique among contemporary monuments. Inside is a ring of smaller bluestones. Inside, these are free-standing trilithons, two bulkier vertical sarsens joined by a single lintel. The whole monument, now in ruins, is aligned towards the sunrise on the summer solstice and sunset on the winter solstice. The stones are set within earthworks in the middle of the densest complex of Neolithic and Bronze Age monuments in England, including several hundred tumuli (burial mounds).

Stonehenge was constructed in several phases beginning about 3100 BC and continuing until about 1600 BC. The famous circle of large sarsen stones was placed between 2600 BC and 2400 BC. The surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. Radiocarbon dating suggests that the bluestones were given their current positions between 2400 and 2200 BC, although they may have been at the site as early as 3000 BC.

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.

Hillforts in Britain refers to the various hillforts within the island of Great Britain. Although the earliest such constructs fitting this description come from the Neolithic British Isles, with a few also dating to later Bronze Age Britain, British hillforts were primarily constructed during the British Iron Age. Some of these were apparently abandoned in the southern areas that were a part of Roman Britain, although at the same time, those areas of northern Britain that remained free from Roman occupation saw an increase in their construction. Some hillforts were reused in the Early Middle Ages, and in some rarer cases, into the later medieval period as well. By the early modern period, these had essentially all been abandoned, with many being excavated by archaeologists in the nineteenth century onward.

There are around 3,300 structures that can be classed as hillforts or similar "defended enclosures" within Britain. Most of these are clustered in certain regions: south and south-west England, the west coast of Wales and Scotland, the Welsh Marches and the Scottish border hills. British hillforts varied in size, with the majority covering an area of less than 1 hectare (2.5 acres), but with most others ranging from this up to around 12 hectares (30 acres) in size. In certain rare cases, they were bigger, with a few examples being over 80 hectares (200 acres) in size.

The history of the British Isles began with its sporadic human habitation during the Palaeolithic from around 900,000 years ago. The British Isles has been continually occupied since the early Holocene, the current geological epoch, which started around 11,700 years ago. Mesolithic hunter-gatherers migrated from the Continent soon afterwards at a time when there was no sea barrier between Britain and Europe, but there was between Britain and Ireland. There were almost complete population replacements by migrations from the Continent at the start of the Neolithic around 4,100 BC and the Bronze Age around 2,500 BC. Later migrations contributed to the political and cultural fabric of the islands and the transition from tribal societies to feudal ones at different times in different regions.

England and Scotland were sovereign kingdoms until 1603, and then legally separate under one monarch until 1707, when they united as one kingdom. Wales and Ireland were composed of several independent kingdoms with shifting boundaries until the medieval period.

A chambered cairn is a burial monument, usually constructed during the Neolithic, consisting of a sizeable (usually stone) chamber around and over which a cairn of stones was constructed. Some chambered cairns are also passage-graves. They are found throughout Britain and Ireland, with the largest number in Scotland.

Typically, the chamber is larger than a cist, and will contain a larger number of interments, which are either excarnated bones or inhumations (cremations). Most were situated near a settlement, and served as that community's "graveyard".

Wayland's Smithy is an Early Neolithic chambered long barrow located near the village of Ashbury in the south-central English county of Oxfordshire. The barrow is believed to have been completed around 3430 BCE by pastoral communities shortly after the introduction of agriculture to the British Isles from continental Europe. Although part of an architectural tradition of long barrow building that was widespread across Neolithic Europe, Wayland's Smithy belongs to a localised regional variant of barrows - found only in south-west of Britain - known as the Severn-Cotswold group. Wayland's Smithy is one of the best surviving examples of this type of barrow.

The site's appearance is a result of restoration following excavations undertaken by archaeologists, Stuart Piggott and Richard Atkinson, from 1962-1963. Their research of the site showed it had been built in two different phases. First as a timber-chambered oval barrow built around 3590 and 3550 BCE and then later as a stone-chambered long barrow in around 3460 to 3400 BCE. The barrow is on the same hill range as Uffington White Horse and Uffington Castle; it is also close to The Ridgeway, the ancient trackway across the Berkshire Downs.

Avebury (/ˈeɪvbəri/) is a Neolithic henge monument containing three stone circles, around the village of Avebury in Wiltshire, in south-west England. One of the best-known prehistoric sites in Britain, it contains the largest megalithic stone circle in the world. It is both a tourist attraction and a place of religious importance to contemporary pagans.

Constructed over several hundred years in the third millennium BC, during the Neolithic, or New Stone Age, the monument comprises a large henge (a bank and a ditch) with a large outer stone circle and two separate smaller stone circles situated inside the centre of the monument. Its original purpose is unknown, although archaeologists believe that it was most likely used for some form of ritual or ceremony. The Avebury monument is a part of a larger prehistoric landscape containing several older monuments nearby, including West Kennet Long Barrow, Windmill Hill and Silbury Hill.
