Holyhead Mountain Hut Circles (Cytiau Tŷ Mawr)
Free Cadw site near South Stack: the stone footings of about 20 roundhouses and other buildings from a prehistoric farming village on the slopes of Holyhead Mountain.
On a sheltered shelf below Holyhead Mountain, a short walk from South Stack, lie the remains of a sizeable prehistoric farming settlement. About 20 of an estimated 50 original buildings can still be traced, mostly the stone foundations of round huts, some with internal divisions, storage areas and stone benches or basins.
Roman coins and pottery found here once led people to think the village was Roman, but it is much older. The Royal Commission on the Ancient and Historical Monuments of Wales records radiocarbon dates pointing to occupation in the Iron Age. The site has been in state care since 1911.
Good to know
Cadw grades the terrain as moderate: the ground is exposed and can be slippery or muddy, and some old steps are uneven. Grazing cattle or farm animals may be nearby. There is no parking at the site itself; the nearest car park is the RSPB one at Ellin's Tower.
