British history: 4000 BC – 1500 BC
It is believed that Stone Age man migrated to Britain across the land bridge that then joined Britain to the rest of Europe. The rising water levels cut Britain off from Europe and left these peoples to develop separately and largely unmolested by any large outside tribes or armies. Stone circles, Neolithic tombs and tools have been found all over the British Isles from the tip of Cornwall in the south to the very north of Scotland. Although Stone Age artefacts can be found all over Britain, the largest of them are found in Wiltshire in southern England. The two largest sites are Avebury and Stonehenge.
Nobody knows what Stonehenge was built for, perhaps Druid temple or perhaps an astronomical calculator. Work started on it in 3100 BC and it was continuously being built, used and modified until 1100 BC. An amazing period of 2000 years - not many other buildings in the world have been used for as long.
After 1100 BC it fell into disuse, again nobody knows why. The stones on the site were used by the local people as a convenient source for building houses and road making. Even up to 100 years ago, local farmers used the stones from Stonehenge for road building and other construction work.
It was given to the nation in 1918, and the government has been responsible for maintaining the monument since then. As Britain's only world heritage site, one can see its importance.
Stone Age man constructed Stonehenge from massive 50 ton blocks of stone. Some were transported along a 240 mile route from the Welsh mountains.
Each stone had a mortise and tenon joint, so that when in place the stones stayed in place. The people who made Stonehenge had no metal tools!
One hypothesis for Stonehenge's being there, is that it was a giant astronomical observatory. The sun on midsummer's day rises above the heel stone on the horizon, and other lies concerning the sun and moon and their movements can be found.
Others believe that it was a druid's temple, or shrine. Whatever interpretation one puts on it, it was a massive and sustained feat to construct and maintain for 2000 years. It is a pity that the site has not been better maintained over the years, but you can still get the feel and majesty of the place.
