see url Today, we’re on a bus heading southwest to Salisbury Plain.  We’ll visit the ancient site of Stonehenge were ancient people built an amazing circle of stones.  No one is quite sure why they built it, but there are many theories. It took thousands of Neolithic people years to do it.  This was the Stone Age so they had no iron tools.  They also dragged the stones from Wales which is over 100 miles away.
