Closer look at one of the Stripple Stones on Bodmin Moor. This is a rather unique arrangement of stones in that it is part of a circle henge, i.e. the stone circle is surrounded by a ditch. Originally there were in the region of 28 stones standing, now half this many remain on the site and only 3 are standing.
