In his paper with Andrew Chamberlain, "Units of measurement in Late Neolithic Southern Britain", 2007, Mike Parker Pearson claimed that the Stonehenge ditch was 106.28 metres in diameter.
Now he claims it is 110 metres to accommodate his latest Waun Mawn stone circle theory.
For myself I see this as a blatant incorporation of tagged-on 'alleged facts' to accommodate a pre-conceived theory and it should be rejected.
Something is not right. This message is just to keep things from messing up down the road
