Using ground-penetrating radar, some 100 stones were found at the Durrington Walls "superhenge", a later bank built close to Stonehenge.

During the ensuing 50 years of land clearance, more large stones were heaped up onto the pile. These continued to ensure that the original area of the monument chamber was protected from later damage by ploughing. http://www.culture24.org.uk/history-and-heritage/archaeology/art522244-skeletons-and-jewellery-in-square-barrows-come-from-iron-age-east-yorkshire-tribe-say-archaeologists It is said that many of them were broken up to build Shap Abbey in 1158, which is, in its turn, dismantled to build paltry houses. Part of the steeple, with trees upon it that have withered with age, and cells under the once body of the abbey, are the only remains of this ruin: it has been shamefully dismantled. A fine stream runs near it, and the ground produces sweet grass, and hay that is all fragrance! Our ancient Irish ancestors carved images of an ancient eclipse into giant stones over 5,000 years ago, on November 30, 3340 BC to be exact. This is the oldest known recorded solar eclipse in history.The probable chieftain or prestigious leader – a man in his thirties or forties – had been interred underneath the centre of a large funerary mound which had been constructed specifically for him inside his own personal 20m diameter ditched enclosure.

Well to add to the story of the person in the 'boat coffin', Jacquetta Hawkes writing in her 'Prehistoric Monuments' tells a somewhat different story, perhaps I should say a more embroidered rendition, considering the only remains found in the coffin was part of a foot, with shoe/clothes, etc. But see Pastscape link below.. Harehaugh Hillfort was built by Iron Age people 2,500 years ago and the essential conservation work now underway will see the hillfort finally removed from the Heritage at Risk register. The east side was surveyed by RCAHM (Wales) for part one of the Caernarfonshire Inventory published in the 1950s but further evidence of prehistoric land use has become more apparent recently, and a new survey as part of a more long-term and comprehensive survey of the hill was commissioned. Well as people find it difficult to get to, some information from Jody Lewis's 'The Neolithic of Northern Somerset'It has been a place of pilgrimage for many centuries and a tourist attraction probably since Roman times. Marking this year’s summer solstice an early Bronze Age sun-disc, one of the earliest metal objects found in Britain, has gone on display for the first time at Wiltshire Museum.
