Bryn Celli Ddu [Map], Anglesey. A Reinterpretation By Claire O'Kelly.

This study presents a reinterpretation of the monument at Bryn Celli Ddu in Anglesey, Wales, excavated in the latter part of the nineteen-twenties by the late W. J. Hemp. A fresh look at his findings in the light of the work being carried out at present at Newgrange, Co. Meath-a site with which Bryn Celli Ddu is often compared-and also in view of the observations made on the Welsh monument as long ago as 1951 by M. J. O'Kelly, suggests strongly that a two-period site, consisting of a henge and a passage- grave, is in question rather than the one-period site postulated by Hemp.
