Bryn Celli Ddu Passage Tomb, Anglesey: Alignment, Construction, Date, and Ritual

Abstract

Bryn Celli Ddu is one of only two developed passage tombs in Wales, and has occupied a pivotal place in narratives of this region since the publication of excavations in the 1920s by W.J. Hemp. The construction sequence at the site has been at the centre of debate on several occasions with previous models raising important issues about the sequence of major monument types (notably the henge and the passage tomb) and the inter-regional links of the tomb's builders. This paper presents a new interpretation of the site's construction history, drawing on several sources, including: the recent demonstration that the tomb is aligned on the midsummer sunrise; Hemp's unpublished archive; and the results of a radiocarbon dating programme. The result is a two phase model which shows the tomb to have been built between3074 and 2956 calbc, and which sheds fresh light on the ritual practices of the community which built it.
