should not be confused with stone or timber circles. They are
elements that can be contained with in a henge, but may also exist on
their own. Look at the examples above. At the top left is a
picture of Avebury Henge which contains a stone circle. On
the bottom left is a picture of Drumbeg Circle in Northern Ireland,
which is a example of a stone circle without a henge around it.
So, is Stonehenge a henge? Well, not exactly. Stonehenge is enclosed by
a ditch, but its bank is built up in the interior of the ditch.
It depends on how picky you want to be.
