Trefignath is located southeast of Holyhead on the Anglesey island of Holy Island in Wales and is a megalithic complex of the Cotswold Severn Tomb . It lies on a rock, 20 m above sea level. The facility was excavated by Smith and Lynch in 1987, revealing a three-phase structure within the remains of the mostly removed stone mound . Remnants of herds and a small selection of finds indicate that the place was already used in the preliminary phase of the cairn construction.
The oldest part is the western chamber, within a small round stone mound, which was built with access to the south over a cavity in the rock. Four large bearing stones are still preserved from it, while the form of the access remained unclear. Radiocarbon dates from the ancient surface show that this site was around 3750-3500 BC. Was built.
The present middle chamber was built next. It is also marked by four bearing stones. Including the round hill, the hill was given a west-east orientation and the typical shape of a wedge-shaped system of the Cotswold-Severn type with the indented forecourt and axial chamber.
Finally, the much better preserved eastern chamber was built in the forecourt and the cairn was extended to its present form. The chamber is almost complete and has two large portal stones in addition to the cap stones.
An arch of post holes and a pit in the forecourt indicate activity. All the chambers were robbed. The remains include shards of Grooved Ware and Flint .
Flint tools , shards and stoves were found on the natural surface of the ground under the cairn . The charcoal was used in this context to 3100 BC. Dated. The ceramic shards from before the construction of the tomb were undecorated round-bottomed Irish Sea ware of the early and middle Neolithic . Local clays probably provided the material for most of the pottery. A small inclusion of perthitic biotite granite in a pot is not of local origin. The pot could come from Cornwall, Ireland or Scotland.
