The current view is that both circuits are contemporary. Radiocarbon dating of antlers deliberately placed in hole Y 30 provided a date of around 1600 BC, a slightly earlier date was determined for material retrieved from Z 29. These dates make the Y and Z holes the last known structural activity at Stonehenge.The holes were discovered in 1923 by William Hawley, who, on removing the topsoil over a wide area noted them as clearly visible patches of ‘humus’ against the chalk substrate. Hawley named them the ‘Y’ and ‘Z’ because for a short time he had earlier labeled the recently discovered Aubrey Holes the ‘X’ holes. 18 of the Y Holes have been excavated and 16 of the Z Holes. Further evidence of the Y and Z Holes being late in the sequence of events at Stonehenge is demonstrated by the fact that hole Z 7 was found to cut into the backfill of the construction ramp for stone 7 of the Sarsen Circle."@en }
