About 4600 years ago - or maybe more - the Stone Age inhabitants of Britain started an enormous stone structure. This structure is now called Stonehenge, and it is near Salisbury, in the South of England.
The largest of the Stonehenge stones weigh 50 tons, and the smallest weighs 5 tons. The people who started Stonehenge were primitive. They used no metal and their tools were made only of stone, bone and wood. Those primitive people usually spent all day, from sunrise to sunset, hunting, fishing and growing crops.
They started to build Stonehenge in about 1000 B.C. and finished it 600 years later. Thousands of man and woman took parting building it.
They builders of Stonehenge could not read or write, so they have left us no records of the work. And we do not know how Stonehenge was build.
