Ponter's Ball Dyke is a linear earthwork located near Glastonbury in Somerset, England. [2] [3] It crosses, at right angles, an ancient road that continues on to the former island of dry land in the Somerset levels surrounding Glastonbury Tor. [4] It consists of an embankment with a ditch on the east side. [1] It is built across the ridge of land between Glastonbury and West Pennard. [1] Both ends of the ditch and dyke disappear into moorland, formerly swamps. [5]
The current visible remains extend to just over 1 kilometre. It is bisected by the A361 and crossed by three public footpaths. [6] The gap where the road runs through the dyke is staggered, suggesting that the gap is original. [1]
It was excavated in 1909 by Arthur Bulleid, [7] and again in 1970 by Peter Poyntz Wright and the Glastonbury Antiquarian Society. [8] Bulleid's excavation just north of the road revealed that the bank was 9 feet high and made of layers of yellow and grey clay, while the ditch was 12 feet deep in hard blue marl. Neither excavation found significant objects with the exception of fragmentary pottery of prehistoric and medieval origin.
Interpretation of the site is not clear. It is possible that it was part of a longer defensive barrier associated with New Ditch three miles to the south-west which is built in a similar manner. It has been suggested that it is part of a great Celtic sanctuary, probably 3rd century B.C., while others date it to the post-Roman period and connect it with the Dark Age occupation on Glastonbury Tor. David Cooper posits that it was the site of the Battle of Posentesbyrg, fought in AD 661 between Cenwalh of Wessex and Wulfhere of Mercia. [9] The 1970 excavation suggests the 12th century or later. [5]
Using LiDAR data of the area to simulate rising sea levels suggests the ditch once ran into marshy land (likely prior to the effective digging of drainage channels). This goes some way to explaining its limited extent. It is also claimed that Ponter’s Ball delineates the long single horn on the head of the Capricorn effigy in the Temple of the Stars, an alleged ancient temple thought to be situated around Glastonbury. [10]
The name Ponter's Ball is said to be derived from "pontis vallum", Latin meaning "the bridge over the ditch." [11] In the early 19th century it was called Ponting's Ball and by 1876 Fronter's Ball. An alternative of Portarius after a family who owned land at Havyatt. [12]
Offa's Dyke is a large linear earthwork that roughly follows the border between England and Wales. The structure is named after Offa, the Anglo-Saxon king of Mercia from AD 757 until 796, who is traditionally believed to have ordered its construction. Although its precise original purpose is debated, it delineated the border between Anglian Mercia and the Welsh kingdom of Powys.
Glastonbury is a town and civil parish in Somerset, England, situated at a dry point on the low-lying Somerset Levels, 23 miles (37 km) south of Bristol. The town had a population of 8,932 in the 2011 census. Glastonbury is less than 1 mile (2 km) across the River Brue from Street, which is now larger than Glastonbury.
Avalon is a mythical island featured in the Arthurian legend. It first appeared in Geoffrey of Monmouth's 1136 Historia Regum Britanniae as a place of magic where King Arthur's sword Excalibur was made and later where Arthur was taken to recover from being gravely wounded at the Battle of Camlann. Since then, the island has become a symbol of Arthurian mythology, similar to Arthur's castle of Camelot.
Glastonbury Tor is a tor near Glastonbury in the English county of Somerset, topped by the roofless St Michael's Tower, a Grade I listed building. The site is managed by the National Trust and has been designated a scheduled monument. The Tor is mentioned in Celtic mythology, particularly in myths linked to King Arthur, and has several other enduring mythological and spiritual associations.
Wansdyke is a series of early medieval defensive linear earthworks in the West Country of England, consisting of a ditch and a running embankment from the ditch spoil, with the ditching facing north.
Combe Hill is a causewayed enclosure, near Eastbourne in East Sussex, on the northern edge of the South Downs. It consists of an inner circuit of ditches and banks, incomplete where it meets a steep slope on its north side, and the remains of an outer circuit. Causewayed enclosures were built in England from shortly before 3700 BC until at least 3500 BC; they are characterized by the full or partial enclosure of an area with ditches that are interrupted by gaps, or causeways. Their purpose is not known; they may have been settlements, meeting places, or ritual sites. The historian Hadrian Allcroft included the site in his 1908 book Earthwork of England, and in 1930 E. Cecil Curwen listed it as a possible Neolithic site in a paper which attempted to provide the first list of all the causewayed enclosures in England.
Devil's Dyke or Devil's Ditch is a linear earthen barrier, thought to be of Anglo-Saxon origin, in eastern Cambridgeshire and Suffolk. It runs for 11 kilometres (6.8 mi) in an almost straight line from Reach to Woodditton, with a 10-metre-high (33 ft) ditch and bank system facing southwestwards, blocking the open chalkland between the marshy fens to the north and the formerly wooded hills to the south. It is a Scheduled Monument, a biological Site of Special Scientific Interest and a Special Area of Conservation.
Below are notable events in archaeology that occurred in 1908.
Devil's Dyke is the remains of a prehistoric defensive ditch which lies at the east side of the village of Wheathampstead, Hertfordshire, England. It is protected as a Scheduled Monument. It is generally agreed to have been part of the defences of an Iron Age settlement belonging to the Catuvellauni tribe of Ancient Britain. It has possible associations with Julius Caesar's second invasion of Britain
Grim's Ditch, Grim's Dyke or Grim's Bank is a name shared by a number of prehistoric bank and ditch linear earthworks across England. They are of different dates and may have had different functions.
Wat's Dyke is a 40-mile (64 km) linear earthwork running through the northern Welsh Marches from Basingwerk Abbey on the River Dee estuary, passing east of Oswestry and on to Maesbury in Shropshire, England. It runs generally parallel to Offa's Dyke, sometimes within a few yards but never more than three miles (5 km) away. It now appears insignificant and is visible in some places as a raised hedgerow and in others no more than a cropmark. The ditch has long since been filled in and the bank ploughed away, but originally it was a considerable construction, considered to be strategically more sophisticated than Offa's Dyke. The date of construction is disputed, ranging from sub-Roman to the early ninth century.
Glastonbury Lake Village was an Iron Age village, situated on a crannog or man made island in the Somerset Levels, near Godney, some 3 miles (5 km) north west of Glastonbury in the southwestern English county of Somerset. It has been designated as a scheduled monument.
The Trundle is an Iron Age hillfort on St Roche's Hill about 4 miles (6 km) north of Chichester, West Sussex, England, built on the site of a causewayed enclosure, a form of early Neolithic earthwork found in northwestern Europe. Causewayed enclosures were built in England from shortly before 3700 BC until at least 3500 BC; they are characterized by the full or partial enclosure of an area with ditches that are interrupted by gaps, or causeways. Their purpose is not known; they may have been settlements, meeting places, or ritual sites. Hillforts were built as early as 1000 BC, in the Late Bronze Age, and continued to be built through the Iron Age until shortly before the Roman occupation.
Meare Lake Village is the site of an Iron Age settlement on the Somerset Levels at Meare, Somerset, England. It is a Scheduled Ancient Monument.
New Ditch is a linear earthwork of possible Iron Age or Medieval construction. It partially crosses the Polden Hills in woodlands approximately 1.1 miles (1.8 km) south-west from the village of Butleigh in Somerset, England.
A cross dyke or cross-dyke is a linear earthwork believed to be a prehistoric land boundary that usually measures between 0.2 and 1 kilometre in length. A typical cross dyke consists of one or more ditches running in parallel with one or more raised banks. Univallate cross dykes typically have a flat-bottomed ditch while the ditches of multivallate cross dykes possess a V-shaped cross-section. A defining characteristic of a cross dyke is that it cuts across the width of an upland ridge or the neck of an upland spur. Cross dykes generally occur at altitudes over 150 metres (490 ft) above mean sea level.
Mendip is a local government district of Somerset in England. The Mendip district covers a largely rural area of 285 square miles (738 km2) ranging from the Mendip Hills through on to the Somerset Levels. It has a population of approximately 110,000. The administrative centre of the district is Shepton Mallet but the largest town is Frome.
Harold St George Gray was a British archaeologist. He was involved in the Pitt Rivers Museum in Oxford and later was the librarian-curator of the Museum for the Somerset Archaeological and Natural History Society.
Beacon Hill, also known as Harting Beacon, is a hillfort on the South Downs, in the county of West Sussex in southern England. The hillfort is located in the parish of Elsted and Treyford, in Chichester District. It is a Scheduled Ancient Monument with a list entry identification number of 1015915. The hilltop enclosure is dated to the Late Bronze Age, from the 8th to 6th centuries BC. The hillfort defences were renewed during the Late Iron Age.
The Battle of Posentesbyrg was fought in AD 661 between the West Saxons under Cenwalh and the Mercians under Wulfhere. It was a victory for the Mercians and Cenwalh was forced to relinquish the territory he had gained from the Britons in Somerset. The exact modern location of the battle is uncertain.
