About
Din Lligwy is a remarkably well-preserved Romano-British enclosed settlement on the Isle of Anglesey, dating primarily from the 4th century AD and representing the home of a prosperous farming family or small community during the later Roman period in Wales. Situated near the village of Moelfre on the north-eastern coast of Anglesey, the site consists of a polygonal stone enclosure wall — still standing to a considerable height in places — containing the foundations and partial walls of a complex of round and rectangular buildings that served the domestic and agricultural needs of its inhabitants.
The combination of round buildings (a traditional pre-Roman Iron Age form) and rectangular buildings (a Roman-influenced addition) visible at Din Lligwy is characteristic of Romano-British settlements across Wales and northern Britain, where native traditions of building and lifestyle persisted alongside and adapted to Roman cultural influences without being replaced by them. The site was occupied before the 4th century, but the substantial masonry construction visible today represents a phase of activity in the late Roman period when the community appears to have been prosperous and well-established.
Archaeological excavations at Din Lligwy in the early 20th century produced an impressive range of finds suggesting the site's occupants were relatively wealthy by the standards of rural Romano-British Wales. These included a substantial hoard of fourth-century Roman coins, evidence of iron-smelting and copper-working, Roman pottery, and personal ornaments. The quantity of metalworking evidence suggests the site was not merely a self-sufficient farmstead but a centre of craft production that participated in the wider Roman-period economy of Anglesey and northern Wales.
The enclosure wall of Din Lligwy — built of large, roughly coursed limestone blocks — encloses an irregular polygonal area of approximately half an acre, within which the building foundations are arranged with a degree of planning and organisation that speaks to the deliberate design of the settlement. The largest building within the enclosure — a rectangular hall-like structure — was probably the principal dwelling or meeting hall of the community, while the surrounding smaller structures served as stores, byres, and workshops.
Din Lligwy is managed by Cadw as a free open-access site. The monument is reached by a short walk from a roadside parking area, passing through attractive Anglesey countryside. The nearby medieval ruined chapel of Capel Lligwy and the Neolithic burial chamber of Lligwy Burial Chamber (both Cadw, also free) are closely related to the Din Lligwy settlement and make the area a compact and rewarding archaeological trail.

💡 Visitor Tips
- Walk the Lligwy triangle — Din Lligwy settlement, Lligwy Burial Chamber, and Capel Lligwy are all within easy walking distance of the same car park and are all free.
- Bring a Cadw guide or download information before visiting — the on-site interpretation board is brief.
- There are no facilities at the site — use the village pub or café in Moelfre before visiting.
- Wellies or sturdy shoes are recommended — the field approach can be muddy in wet weather.
- Allow 30–45 minutes for Din Lligwy alone, plus extra time if walking the Lligwy trail.
- The site is at its most evocative in low winter light when the walls cast long shadows — a good alternative to summer visits.
- The finds from this site (Roman coin hoard, pottery, metalwork) are in the National Museum Wales, Cardiff — worth seeing if visiting Cardiff.
- Combine with Bryn Celli Ddu and Barclodiad y Gawres for a full Anglesey prehistoric and Roman day.
Highlights
Enclosure Wall
The enclosure wall of Din Lligwy is the most immediately striking feature of the site — a polygonal boundary of large, roughly coursed limestone blocks, still standing to over a metre in height in several sections, that defines and encloses the settlement area. This is not a defensive wall in the manner of a hillfort rampart but rather a substantial boundary marking the extent of the settlement and separating the community's domestic and working spaces from the surrounding agricultural land.
The quality of the construction — the careful selection and positioning of large limestone blocks — speaks to the resources and organisation available to the community, and the wall's survival to significant height after 1,600 years is a testament to the quality of the original building.
Round and Rectangular Buildings
Within the enclosure at Din Lligwy, the foundations and lower walls of at least nine distinct buildings are visible — a mixture of round structures, which represent the traditional pre-Roman Iron Age building form that continued in use throughout the Roman period in Wales, and rectangular buildings, which reflect Roman-influenced architectural norms that had been adopted by this community in the 4th century AD.
This architectural duality is characteristic of Romano-British settlements in Wales, where native traditions persisted and adapted alongside Roman influences. The largest rectangular building — a substantial hall — was probably the principal dwelling or communal space, while the surrounding structures served as ancillary domestic and agricultural buildings.
Evidence of Romano-British Prosperity
Excavations at Din Lligwy revealed a picture of a community that was, by the standards of 4th-century rural Wales, relatively prosperous and economically active. The find of a hoard of Roman coins — several hundred 4th-century copper-alloy coins — suggests the community was participating in the monetary economy of Roman Britain rather than operating purely as a subsistence farming unit.
Evidence of iron-smelting and copper-working indicates the presence of craftspeople alongside the farming household, and imports of Roman pottery, glass, and personal ornaments point to engagement with the wider trading networks of late Roman Britain.
Din Lligwy presents a vivid picture of life in northern Wales under Roman provincial influence.
The Lligwy Archaeological Trail
Din Lligwy is one of three significant Cadw monuments in close proximity near Moelfre, which together form an informal archaeological trail spanning several thousand years of Anglesey history. The Neolithic burial chamber of Lligwy (Cadw, free), approximately 400 metres south of Din Lligwy, is a large portal dolmen dating from around 3000 BC, with a massive capstone and a somewhat different character from Bryn Celli Ddu.
The ruined medieval chapel of Capel Lligwy (Cadw, free), a 12th-century Norman chapel ruin immediately adjacent to the Neolithic chamber, completes the sequence from Neolithic to medieval.
Walking all three sites in a circuit from the parking area takes approximately 90 minutes.
Collections
Din Lligwy is an unmanned open-access site with no permanent collection on site. Finds from excavations, including the Roman coin hoard, pottery, and metalworking evidence, are held in the National Museum Wales in Cardiff. A Cadw interpretation board at the site provides contextual information.
Visitors seeking more detail should consult National Museum Wales resources or Cadw's online information.
