About Lligwy Burial Chamber
Lligwy Burial Chamber is a Neolithic portal dolmen on eastern Anglesey — one of the most striking megalithic monuments in Wales, its massive limestone capstone (approximately 25 tonnes) resting on a group of low uprights over a chamber set partly below ground level. The monument dates to approximately 3500 BC, placing it among the earliest monumental architecture in Britain — older than Stonehenge by over a thousand years. When excavated in 1909, the chamber yielded the remains of approximately 15–30 individuals alongside pottery and animal bones from the Neolithic and early Bronze Age periods, indicating use as a communal burial monument over many generations.
The design of Lligwy is unusual: rather than the tall, dramatic profile of many Welsh portal dolmens, the capstone rests close to ground level, the chamber having been sunk into the earth. This gives the monument a low, crouching quality — the scale of the stone only becomes apparent on approach, as the 5.5-metre capstone resolves from what initially appears as a natural rock outcrop into a deliberate, carefully positioned megalith. The Neolithic community that built and used Lligwy would have been farming the fertile Anglesey lowlands around 3500–3000 BC, creating a permanent monument to their dead in the landscape they farmed.
Immediately adjacent (0.5 miles by footpath) is Din Lligwy — a remarkably well-preserved Romano-British settlement of the 4th century AD. Combining the burial chamber, Din Lligwy, and the nearby ruin of Capel Lligwy (12th century) makes a walk of approximately 2 miles through 5,000 years of human occupation of the same small area of Anglesey.

Frequently asked questions
Lligwy Burial Chamber is a Neolithic megalithic tomb on eastern Anglesey, dating to approximately 3500 BC — making it over 5,500 years old. It is a portal dolmen: a low chamber formed by upright stones and sealed by a massive capstone. The Lligwy capstone is one of the largest in Wales, measuring approximately 5.5 × 4.5 metres and weighing approximately 25 tonnes. The chamber sits in a natural depression in the ground, with the huge capstone appearing to rest barely above the field level — an unusual design compared with the more towering dolmens found elsewhere in Wales. Archaeological excavation in 1909 found the remains of approximately 15–30 individuals buried within, along with pottery and animal bone fragments from the Neolithic and early Bronze Age periods.
Lligwy Burial Chamber is reached via a short field path (approximately 200 metres) from a small parking area on the minor road east of Llangefni, near the hamlet of Lligwy (postcode LL72 8NF). The path crosses agricultural fields to the monument, which is in open farmland. A car is the most practical way to reach it — nearest bus services connect Moelfre (2 miles away) but there is no bus stop adjacent to the site. The burial chamber is managed by Cadw as a Scheduled Ancient Monument, open at all times with free access. Immediately nearby (0.5 miles, via footpath) is Din Lligwy — a well-preserved Romano-British settlement — making a combined visit worthwhile.
Lligwy and Bryn Celli Ddu are the two best-known Neolithic monuments on Anglesey, but they are quite different in type. Bryn Celli Ddu (12 miles west of Lligwy) is a passage tomb — a stone-lined passage leads into an internal chamber, covered by an earth mound. It is architecturally more sophisticated and has a famous solar alignment at midsummer sunrise. Lligwy is a portal dolmen — a simpler type of tomb with a single large chamber covered by a massive capstone. The scale of Lligwy's capstone (25 tonnes) is extraordinary — how a Neolithic community without machinery moved and positioned such a stone is a matter of ongoing interest. Both monuments are free Cadw sites and worth visiting in combination.
The area around Lligwy contains an unusually dense cluster of historic monuments. Within half a mile of the burial chamber: Din Lligwy is a remarkable late Romano-British village — a walled enclosure of stone roundhouses and rectangular buildings occupied approximately AD 300–400, one of the best-preserved later prehistoric settlements in Wales. A few hundred metres away, Capel Lligwy is the ruin of a 12th-century chapel on an early Christian site, also managed by Cadw and free to visit. The combination of Neolithic burial chamber, Romano-British village, and early medieval chapel in a small area makes the Lligwy cluster one of the most rewarding heritage walks on Anglesey for visitors interested in the full depth of the island's human history.
The burial chamber is open at all times and accessible year-round. The surrounding farmland can be muddy in autumn and winter, making stout footwear advisable. The monument is in open countryside with no shade — a sunny summer day gives the most atmospheric visit. Early morning or evening light emphasises the massive size of the capstone and the texture of the ancient stones. Unlike Bryn Celli Ddu, there is no particular astronomical alignment at Lligwy, so no specific time of year is significant for astronomical reasons. The monument has no visitor facilities (no toilets, café, or information board on site) — Cadw's information about the site is available online and in the Oriel Ynys Môn museum in Llangefni.
