Holyhead Mountain Hut Circles
Holyhead Mountain Hut Circles, also known as Cytiau'r Gwyddelod (the Irishmen's Huts), represent one of the most remarkably preserved Iron Age and Romano-British settlement sites in Wales, sitting on the rugged western flank of Holyhead Mountain on the Isle of Anglesey. The site comprises the remains of around twenty circular stone huts clustered together within an enclosed area, the remnants of a small farming community that thrived here for several centuries spanning the late Iron Age through to the Roman period, roughly from around 100 BC to 400 AD. The sheer density and state of preservation of these structures make Cytiau'r Gwyddelod exceptional among prehistoric settlements in Wales, earning it Scheduled Ancient Monument status and making it one of the most important archaeological sites in northwest Wales.
The huts themselves are built from the local igneous rock of Holyhead Mountain, their low circular stone walls still standing to considerable height in places, with some walls reaching nearly a metre or more above ground level. Each hut would originally have been topped with a thatched or turf roof supported by timber posts, sheltering families who combined pastoral farming with perhaps some degree of fishing and trade. The name Cytiau'r Gwyddelod, translating loosely as "huts of the Irish," likely reflects later medieval Welsh tradition associating mysterious ancient structures with Irish or foreign peoples, rather than any verified ethnic identity of the original inhabitants, who were almost certainly local Celtic Britons. Some finds from the site and nearby areas suggest continued use or at least awareness of the site during the Roman period, when nearby Caer Gybi fort at Holyhead was a Roman coastal fortification.
Walking through the site today is a quietly absorbing experience. The worn stone rings emerge from the heather and rough grassland like the outlines of a lost world, their grey stones patched with orange and grey lichen and softened by centuries of weathering. On a still day the silence is broken only by the wind sweeping in from the Irish Sea and the occasional call of a chough or raven, birds that have long inhabited this rocky headland. The elevation of the site provides sweeping views westward over the sea toward Dublin Bay on clear days, northward toward the South Stack lighthouse, and eastward across Anglesey's flat agricultural hinterland. Standing inside one of these ancient circular enclosures, the sense of human continuity across millennia is palpable and affecting.
The landscape surrounding Holyhead Mountain is itself exceptional. At 220 metres, the mountain is the highest point on Anglesey and the broader island of Holy Island, upon which it stands. The hillsides are rich in heather and gorse, frequented by rare birds including the red-billed chough, which finds the rocky terrain ideal for foraging. Just over a kilometre to the southwest lies South Stack, one of Wales's most dramatic coastal landmarks, where a lighthouse perches on a small island reached by a suspension bridge above crashing Atlantic waves, and where RSPB South Stack Cliffs reserve protects nesting seabirds including puffins, razorbills and guillemots. The Iron Age hillfort of Caer y Twr crowns the summit of Holyhead Mountain itself, only a short walk from the hut circles, and together the two sites constitute an extraordinary concentration of ancient human history on a single mountain.
Reaching the hut circles requires a moderate uphill walk from the trailheads near South Stack. The most popular approach begins from the RSPB car park at Ellin's Tower near South Stack, from which well-marked paths climb the mountain. Alternatively, visitors approaching from Holyhead town can find paths beginning near the edge of the urban area leading up onto the mountain. The walk to the hut circles is approximately two kilometres from the South Stack car park and involves some uneven rocky terrain, making sturdy footwear essential. The site itself has no fencing or formal visitor infrastructure; it is simply open land through which the path passes, and visitors are free to wander among the ruins respectfully. There is no charge for visiting.
The best time to visit is late spring through early autumn, when the heather is in bloom and weather conditions are most benign, though the mountain can be visited year round by those suitably prepared. Early morning visits reward walkers with the best light on the stones and the quietest conditions before the South Stack area becomes busier with birdwatchers and tourists. The site is managed by Cadw, the Welsh Government's historic environment service, and is protected under scheduled monument legislation. Dogs are welcome on leads. Visitors should be aware that the coastal mountain environment can change weather rapidly, and appropriate clothing and navigation awareness are advisable even for relatively short walks.
One of the more intriguing aspects of the site is what excavations and surveys have revealed about the daily life of its inhabitants. Evidence of metalworking, grain processing, and textile production has been found in and around similar hut circle settlements on Anglesey, suggesting these were not merely seasonal shelters but permanent homesteads of considerable complexity. The siting of the settlement on the western flank of the mountain rather than its summit hints at a careful balance between elevation for defence and visibility and shelter from the prevailing Atlantic winds. The community that lived here would have watched the same sunsets over the Irish Sea that visitors watch today, in a landscape that, stripped of modern intrusions, would look remarkably similar to what they knew. That continuity of place, stretching back over two thousand years, is ultimately what makes Cytiau'r Gwyddelod so quietly powerful to visit.
