where did the stones come from to build stonehenge
Stonehenge Archaeological excavation has indicated that around 2600 BC, the builders abandoned timber in favour of stone and dug two concentric arrays of holes (the Q and R Holes) in the centre of the site. These stone sockets are only partly known (hence on present evidence are sometimes described as forming 'crescents'); however, they could be the remains of a double ring. Again, there is little firm dating evidence for this phase. The holes held up to 80 standing stones (shown blue on the plan), only 43 of which can be traced today. It is generally accepted that the bluestones (some of which are made of dolerite, an igneous rock), were transported by the builders from the Preseli Hills, 150 miles (240Â km) away in modern-day Pembrokeshire in Wales. Another theory is that they were brought much nearer to the site as glacial erratics by the Irish Sea Glacier[23] although there is no evidence of glacial deposition within southern central England.[24]
Arch The ancient Romans learned the arch from the Etruscans, refined it and were the first builders to tap its full potential for above ground buildings:
Stonehenge Stonehenge is a prehistoric monument in Wiltshire, England, 2 miles (3 km) west of Amesbury and 8 miles (13 km) north of Salisbury. It consists of a ring of standing stones, with each standing stone around 13 ft (4.1 metres) high, 6 ft 11 in (2.1 metres) wide and weighing around 25 tons. The stones are set within earthworks in the middle of the most dense complex of Neolithic and Bronze Age monuments in England, including several hundred burial mounds.[1]
Curling The granite for the stones comes from two sources: Ailsa Craig, an island off the Ayrshire coast of Scotland, and the Trefor Granite Quarry in Wales.
