“ Anglesey is as interesting to the antiquary, as to the natural philosopher. The ancient British vestiges are very numerous; comprising no less than twenty-eight cromlechs, or Druidical altars, together with circles, monumental stones, entrenchments, and other remains of a similar description, both British and Roman, which will receive attention in their proper places; several of the parish churches (of which the whole, seventy-four, stand near the coast) , with various monastic remains, also deserve examination on the score of antiquity. ”
