Barclodiad-y-Gawres

The alignment of the chamber at Barclodiad-y-Gawres has been puzzling me lately. The Irish passage graves – of which this is surely one – were sometimes aligned on the sun. Newgrange is the classic example, aligned on the midwinter sunrise.

The orientation of the passage at Barclodiad-y-Gawres is just about due north, as measured with a compass, which means that it cannot be aligned on any movement of the sun.

It is, however, aligned on a pair of low hills in the distance – Mynydd y Garn and Mynydd Mechell. The standing stones of Llanfechell lie at the foot of the latter.

The horizon on this part of Anglesey is remarkably flat and level, so these hills do stand out on a clear day. The obvious feature of the horizon is the great lump of Holyhead Mountain, but the passage points instead to the two smaller hills. I’ve attached a photograph of these from the passage.

Was this a deliberate alignment? Were these sacred hills? I don’t know. Go there on a clear day, sit in the clear air of Anglesey, soak up the view and see what you think.
