Barclodiad y Gawres is the only attested example of a cruciform type in North Wales. The monument is one of the most impressive decorated megalithic monuments in north-western Europe. The passage, measuring approximately 6m and leads to a cruciform passage which has a series of uprights decorated with chevrons, lozenges, spirals and zigzag designs. Powell and Daniel excavated much of the passage and chamber areas, along with sections of the mound. The chamber area was once covered by at least several enormous capstones. The chamber and passage architecture prior to excavation was not covered. The forecourt area opens out onto views across the western coast of Ynys Mon. Within the central chamber was discovered a hearth approximately 1m in diameter which contained a mixture of charcoal and stone chips. Also recovered was an assemblage of shells, fish bones, and the bones of amphibia, reptiles and small mammals. Powell also excavated Dyffryn Ardudwy in 1973.
