Time Team - Rhyd-y-Groes Wind Farm, Werthyr, Near Amlwch, Anglesey, North Wales - Archaeological Evaluation and Assessment of Results

Wessex Archaeology

No clear date for the earthworks was revealed. However, the project was successful in the identification of large enclosing defensive ditches through both geophysical survey and excavation. The geophysical survey revealed the extent of the enclosure but was unable to reveal any contemporary structures within it, due to the effects of later ploughing.

A possible Bronze Age cist grave was identified which may have been sealed beneath a cairn, although the lack of skeletal remains and grave goods makes the identification of this feature tentative, and its date difficult to ascertain.

The interpretation and dating of the earthworks and underlying archaeology was derived largely from comparisons with other similar excavated sites on Anglesey. An aerial photography survey undertaken as part of this programme of works identified a series of enclosures to the north of the main defended site which have been interpreted as animal corrals and agricultural boundaries.
