It has been suggested that the Aubrey holes were originally intended to be postholes containing timbers or stones but this is uncertain. Analogous timber circles at sites such as Woodhenge have influenced this interpretation; the positioning of the Aubrey Hole circle relative to the earth bank and ditch at Stonehenge is reproduced at similar sites with rings of timber postholes. That the holes appear to have been filled soon after excavation and then possibly redug does not exclude the possibility that they held timber posts which were replaced intermittently. No evidence of postpipes has been recovered with the holes although modern archaeological excavation techniques have not been applied to the pits. If the putative timbers were purposefully removed when they fell out of use, then even this evidence would be difficult to spot however. The lack of full documentation from the early Stonehenge digs in the twentieth century and the disturbance caused by the insertion of the later cremations during Stonehenge 2 have also added to the uncertainty over the function of the holes.
