Stonehenge

Stonehenge is probably the most important prehistoric monument in the
whole of Britain and has attracted visitors from earliest times. It stands as a timeless monument to the people who built it.
The stonehenge that we see today is the final stage that was completed about 3500 years ago, but first let us look back 5000 years.
The first Stonehenge was a large earthwork or Henge, comprising a ditch, bank, and the Aubrey holes, all probably built around 3100 BC. The Aubrey holes are round pits in the chalk, about one metre wide and deep, with steep sides and flat bottoms. They form a circle about 284 feet in diameter. Excavations have revealed cremated human bones in some of the chalk filling, but the holes themselves were probably made, not for the purpose of graves, but as part of the religious ceremony. Shortly after this stage Stonehenge was abandoned, left untouched for over 1000 years.
The second and most dramatic stage of Stonehenge started around 2150 BC. Some 82 bluestones from the Preseli mountains, in south-west Wales were transported to the site. It is thought these stones, some weighing 4 tonnes each were dragged on rollers and sledges to the headwaters on Milford Haven and then loaded onto rafts. They were carried by water along the south coast of Wales and up the rivers Avon and Frome, before being dragged overland again to near Warminster in Wiltshire. The final stage of the journey was mainly by water, down the river Wylye to Salisbury, then the Salisbury Avon to west Amesbury.
This astonishing journey covers nearly 240 miles. Once at the site, these stones were set up in the centre to form an incomplete double circle. ( During the same period the original entrance of the circular earthwork was widened and a pair of Heel Stones were erected. Also the nearer part of the Avenue was built, aligned with the midsummer sunrise.)
The third stage of Stonehenge, about 2000 BC, saw the arrival of the Sarsen stones, which were almost certainly brought from the Marlborough Downs near Avebury, in north Wiltshire, about 25 miles north of Stonehenge. The largest of the Sarsen stones transported to Stonehenge weigh 50 tonnes and transportation by water would have been impossible, the stones could only have been moved using sledges and ropes. Modern calculations show that it would have taken 500 men using leather ropes to pull one stone, with an extra 100 men needed to lay the huge rollers in front of the sledge.
These were arranged in an outer circle with a continuous run of lintels. Inside the circle, five trilithons were placed in a horseshoe arrangement, whose remains we can still see today.
The final stage took place soon after 1500 BC when the bluestones were rearranged in the horseshoe and circle that we see today. The original number of stones in the bluestone circle was probably around 60, these have long since been removed or broken up. Some remain only as stumps below ground level.
Stonehenge was produced by a culture that left no written records. Many aspects of Stonehenge remain subject to debate. This multiplicity of theories, some of them very colourful, is often called the "mystery of Stonehenge".

There is little or no direct evidence for the construction techniques used by the Stonehenge builders. Over the years, various authors have suggested that supernatural or anachronistic methods were used, usually asserting that the stones were impossible to move otherwise. However, conventional techniques using Neolithic technology have been demonstrably effective at moving and placing stones of a similar size.Proposed functions for the site include usage as an astronomical observatory, or as a religious site.

More recently two major new theories have been proposed. Professor Mike Parker Pearson, head of the Stonehenge Riverside Project, has suggested that Stonehenge was part of a ritual landscape and was joined to Durrington Walls by their corresponding avenues and the River Avon. He suggests that the area around Durrington Walls Henge was a place of the living, whilst Stonehenge was a domain of the dead. A journey along the Avon to reach Stonehenge was part of a ritual passage from life to death, to celebrate past ancestors and the recently deceased.On the other hand, Geoffery Wainwright, president of the Society of Antiquaries of London, and Timothy Darvill of Bournemouth University have suggested that Stonehenge was a place of healing – the primeval equivalent of Lourdes. They argue that this accounts for the high number of burials in the area and for the evidence of trauma deformity in some of the graves. However they do concede that the site was probably multifunctional and used for ancestor worship as well. Isotope analysis indicates that some of the buried individuals were from other regions. A teenage boy buried approximately 1550 BC was raised near the Mediterranean Sea; a metal worker from 2300 BC dubbed the "Amesbury Archer" grew up near the alpine foothills of Germany; and the "Boscombe Bowmen" likely arrived from Wales or Brittany, France.
Whatever religious, mystical or spiritual elements were central to Stonehenge, its design includes a celestial observatory function, which might have allowed prediction of eclipse, solstice, equinox and other celestial events important to a contemporary religion
