Earthen barrows; Looking at Martin Green's book on that area, he describes them as 'empty' barrows but which have recently been recognised as belonging to a type known as 'bayed' longbarrows.... the mounds have a stake fence built down the long axis, with intervals of shorter fences at right angles, gving the bayed effect, or the division of labour maybe over a period of time.... as they have no burials, could have been a marking of land/territory - following that, and this is pure speculation, given the Dorset cursus and the dykes in that area, continuing right down to the saxons, could land have been split up territorially over such a long time period I wonder...
