These Ancient Field Systems can be found on the west coast of Wales in Dyffryn Ardudwy, Gwynedd. The field systems are defined by the 6ft thick stone walls, constructed from stones and boulders cleared from the fields during preparation for agriculture.
(Boulder walls are a type of single wall in which the wall consists primarily of large boulders, around which smaller stones are placed)
The boulders were an important part of the culture for the early inhabitants of these lands, as is evidenced by the great numbers of cromlechs, standing stones and cairns peppered about the hillside. Indeed the Dyffryn Ardudwy Burial Chamber just on the edge of the village is estimated to be between 5,000 and 6,000 years old.
The walls themselves date from prehistoric times, some are Iron Age or possibly even Bronze Age in origin, others are from the Roman period. It is also worth bearing in mind that in some cases the more modern walls have been built on the foundations of the prehistoric ones, thus perpetuating the ordering of the agricultural landscape originally laid out millennia before Christ.
