Primary Reference Number (PRN) : 2694 Trust : Gwynedd Community : Llanddaniel Fab Unitary authority : Ynys Mon NGR : SH50767018 Site Type (preferred type first) : Neolithic CHAMBERED TOMB Status : Scheduled Monument , Cared for by the State
Summary : Bryn Celli Ddu is a well known and well visited monument comprising two phases of use. The first phase is a henge and includes a ditch, originally with an outer bank, a ring of stones around the inside and possible a central feature. The second phase, which almost entirely obliterates the first, is a burial chamber of classic passage grave type comprising a high-roofed polygonal chamber and a lower entrance passage, containing a rounded stone pillar. A pit and a decorated stone found beside it are also thought to belong to this later phase. The entire monument was originally covered by an earth and stone mound which, after excavation by W.J.Hemp between 1927-31, was restored only around the chamber and passage.
It has been suggested that the obliteration of the first phase by the passage grave represents the deliberate 're-dedication' of the site maybe as a result of antagonism between two different religious systems.

Bryn Celli Ddu may be linked with the Passage Graves of Brittany although the exact relationship is not clear. It must, however, be late in any series since it overlies an apparent henge monument... possibly A. T. Kinsai's Class II (Beaker period). <6>
'Passage grave' excavated in 1929 and restored. Detailed description in Lynch etc. Too well known to require further description. Set on local summit with good views all around. (Smith, 2003)
