Cadbury Castle, Somerset

Cadbury Castle is a Bronze and Iron Age hillfort in the civil parish of South Cadbury in the English county of Somerset. It is a scheduled monument and has been associated with King Arthur's legendary court at Camelot.

The hillfort is formed by a plateau surrounded by ramparts on the surrounding slopes of the limestone Cadbury Hill. The site has been excavated in the late 19th and early 20th century by James Bennett and Harold St George Gray. More recent examination of the site was conducted in the 1960s by Leslie Alcock and since 1992 by the South Cadbury Environs Project. These have revealed artifacts from human occupation and use from the Neolithic through the Bronze and Iron Ages. The site was reused by the Roman forces and again from c. 470 until some time after 580. In the 11th century, it temporarily housed a Saxon mint. Evidence of various buildings at the site has been unearthed, including a "Great Hall", round and rectangular house foundations, metalworking, and a possible sequence of small rectangular temples or shrines.

Background

Hillforts developed in the Late Bronze and Early Iron ages, around the start of the 1st millennium BC. The reason for their emergence in prehistoric Britain and their purpose has been a subject of debate. It has been argued that they could have been military sites constructed in response to invasion from continental Europe, sites built by invaders, or a military reaction to social tensions caused by an increasing population and consequent pressure on agriculture. The dominant view since the 1960s has been that the increasing use of iron led to social changes in Britain. Deposits of iron ore were located in different places from the tin and copper ore necessary to make bronze and, as a result, trading patterns shifted. The old elites lost their economic and social status and power passed into the hands of a new group of people.

Archaeologist Barry Cunliffe believes that population increase still played a role and has stated that

Location

Cadbury Castle is located north east of Yeovil. It stands on the summit of Cadbury Hill, a limestone hill situated on the southern edge of the Somerset Levels, with flat lowland to the north. The summit is above sea-level on lias stone.

The hill is surrounded by terraced earthwork banks and ditches and a stand of trees. On the north west and south sides there are four ramparts, with two remaining on the east. The summit plateau covers , and is surrounded by the inner bank which is long. The hill fort is overlooked by Sigwells, a rural plateau rich in archaeological remains. Due to scrub and tree growth the site has been added to the Heritage at Risk Register.

History

Early occupation of the site

The earliest settlement on the site is represented by pits and post holes dated with Neolithic pottery and flints. These are the remains of a small agricultural settlement which was unenclosed. Bones recovered from the site have been radiocarbon dated to 3500 and 3300 BC. A bank under the later Iron Age defences is likely to be a lynchet or terrace derived from early ploughing of the hilltop. The site was also occupied in the Late Bronze Age, from which ovens have been identified. Radical revisions of the Bronze Age archaeology on the lower slopes resulted from discoveries during excavations and survey work by the South Cadbury Environs Project. Finds include the first Bronze Age shield from an excavation in northwest Europe, an example of the distinctive Yetholm-type. Carbon dating implies that the shield was deposited in the 10th century BC, although metallurgical evidence suggests that it was manufactured two centuries earlier. A metal-working building and associated enclosure were discovered south east of the hillfort, roughly contemporary with the period of manufacture.

Human occupation continued throughout the Iron Age. A stone enclosure was constructed around 300 BC with timber revetting, and ploughing ceased within the hilltop site. Excavations have shown the signs of four and six post rectangular buildings which were gradually replaced with roundhouses. Large ramparts and elaborate timber defences were constructed and refortified over the following centuries. Excavation revealed round and rectangular house foundations, metalworking, and a possible sequence of small rectangular temples or shrines, indicating permanent oppidum-like occupation. Excavations were undertaken by local clergyman James Bennett in 1890 and Harold St George Gray in 1913, followed by major work led by archaeologist Leslie Alcock from 1966 to 1970. He identified a long sequence of occupation on the site and many of the finds are displayed in the Museum of Somerset in Taunton. The finds from the Late Bronze Age to the Early Iron Age, exploring the ramparts and southwestern gate structure, represent one of the deepest and most complex Iron Age stratigraphic sequences excavated in southern Britain.

Castle

During the first century BC additional lines of bank and ditch were constructed turning it into a multivallate hillfort which is now known as the ''castle''. There is evidence that the fort was violently taken in around 43 and that the defences were further slighted later in the 1st century after the construction of a Roman army barracks on the hilltop. Excavations of the southwest gate in 1968 and 1969 revealed evidence for one or more severe violent episodes, associated with weaponry and destruction by fire. Whereas the excavator, Leslie Alcock, believed this to have been dated to around AD 70, Richard Tabor argues for a date associated with the initial invasion, either 43 or 44. Michael Havinden states that it was the site of vigorous resistance by the Durotriges and Dobunni to the second Augusta Legion under the command of Vespasian. There was significant activity at the site during the late third and fourth centuries, which may have included the construction of a Romano-British temple.

Post-Roman occupation

Following the withdrawal of the Roman administration, the site is thought to have been in use from until some time after 580. Alcock revealed a substantial "Great Hall" and showed that the innermost Iron Age defences had been refortified, providing a defended site double the size of any other known fort of the period. Shards of pottery from the eastern Mediterranean were also found from this period, indicating wide trade links. It therefore seems probable that it was the chief ''caer
