Here this should answer you question as I have just read it. http://www.stonehenge.co.uk/

1) "Stonehenge is a prehistoric monument located in the English county of Wiltshire, about 8 miles (13 km) north of Salisbury. One of the most famous prehistoric sites in the world, Stonehenge is composed of earthworks surrounding a circular setting of large standing stones. Archaeologists believe that the standing stones were erected around 2200 BC and the surrounding circular earth bank and ditch, which constitute the earliest phase of the monument, have been dated to about 3100 BC. The site and its surroundings were added to the UNESCO's list of World Heritage Sites in 1986 in a co-listing with Avebury henge monument, and it is also a legally protected Scheduled Ancient Monument. Stonehenge itself is owned by the Crown and managed by English Heritage while the surrounding land is owned by the National Trust."

Researchers Jenny Blain and Robert J. Wallis (Sacred Sites, Contested Rites/Rights project [2]) have pointed to the huge variety of views which show the continued and growing importance of Stonehenge today, as symbol and 'Icon of Britishness'; and indicate also the increased awareness of pasts by many people with no training in archaeology or heritage. For many, Stonehenge and other ancient monuments form part of the 'living landscape' which holds its own stories and which is there to be engaged with as people mark the seasons of the year. Today's mythology around Stonehenge includes the recent history of the Battle of the Beanfield and the previous Free festivals. Stonehenge has not one meaning but many. Today, curators English Heritage facilitate 'managed open access' at solstices and equinoxes, with some disputes over the days on which these fall. Blain and Wallis argue that issues over access relate not only to physical presence at the stones but to interpretations of past and validity of 'new-indigenous' and pagan usages in the present and such 'alternative' views have been central in alerting public awareness to the issues of roads, tunnels and landscape."

As to the history of how it was built, we have already some theories about this but we shall learn more in the future. I would not risk a guess.
