English: Cattle grazing within a hut circle above Porth Dafarch This hut circle, one of many in this area, dates from the Iron Age. These hut circles are known, in Welsh, and marked thus on the map, as Cytiau'r Gwyddelod, (which in modern Welsh translates as "hutments of the Irish"). This does not necessarily mean that they were ever inhabited by colonists from across the Irish Sea, although colonisation of the Welsh coastlands by the Irish did take place in the post-Roman period. The Old Welsh word Gwyddel, which was later adopted into Irish as Goidel, means a wild/fierce person and could have been equally used by later generations to describe the hutments of their more primitive Iron Age ancestors.
