IMHO - "The Stonehenge of the North" is a must have NOT tag. People expect to see stone lintels etc. When they don't, they then are disappointed and ask "what is all the fuss about?" Tell it how it is - not how it isn't. It should be sold in its own right - three giant linked circles - cursus - orion etc. The "henge" word is an unfortunate one that misleads Joe Public. Try for a new name along the lines of "Thornborough Complex"
