Across the British Isles can be found prehistoric remains which date from the period 3,000 BC to 1,500 BC, and take the form of a number of stones standing in a circle. The reason for their construction, and the role they played in the society of the time are now unknown. The most famous stone circle is Stonehenge in Wiltshire, England, but in all there are almost 1,000 other stone circles.
