Barclodiad y Gawres Burial Chamber

Aberffraw, Anglesey

Location Guide

 

Photo By Raw West

This burial chamber is a restored chambered cairn, and dates from 3000BC. It is the largest of the chambered tombs of Wales. It is dramatically situated on a headland to the north of Porth Trecastell (Cable Bay) on the west coast of Anglesey. The site has been extensively restored with a new stone wall supporting a concrete roof covered in turf.

The name translates into English as the Giantess's Apronful.

The chambered cairn Barclodiad Y Gawres is the largest Neolithic tomb in Wales. It was built around the same time as the Egyptian Pyramids and Stonehenge in Wiltshire, somewhere between 2500-3000BC. It was excavated in the 1930's and the mound reconstructed with a turf covered concrete dome. The now hollow dome was originally solid earth. It was a public grave for the local farming community and it is said that it probably acted as a focus for religious ceremonies.

Although today we assume they were tombs, this may have been a later use, and they may have been a secure store or cool food store as part of a household or for a community. Many structures like this had entrances that required the person entering to bow or crawl into them, so they would as have been a secure place that could be easily defended. Structures like these were shown to have been around for a long time so their use may have changed over time, starting perhaps as a safe cave, then a community cold store, before being used as a place to put the dead. Where only a few bodies have been found it may just be that they were used for shelter from the elements when the weather was very bad and the entrance was sealed suffocating those inside. There is no evidence one way or another as to their use, and therefore as the remains of bodies were found in them, it is fair to assume to one point they were used for burials, and as many were earth filled at this point this would have been their final use.

Five of the interior stones are decorated with incised zigzags, lozenges and spirals, these may have some meaning or maybe were just the art of the time.

The entrance was through a long, stone lined passage leading to a central area. From this there are three separate side chambers, all originally covered by large capstones. One of the capstones is visible today.

It is said that many aspects of the tomb, and of its decorated stones, are similar to Neolithic monuments in the Boyne Valley in Ireland, suggesting a link between the cultures at the time. Its location overlooking the sea may also have had significance.

Tombs of this type, known as a decorated Cruciform Passage Grave,  are usually only found in Ireland and reach their peak in the tombs of the Boyne valley area, a similar tomb can be found at Fourknocks. Other than this site, the only other known possible site may have been a similar tomb at Calderstones near Liverpool. Six stones recovered from this site do bear "Irish style" rock art, but the Calderstones monument has been completely destroyed and its original design and function is therefore unknown, it was, at one point, thought to have been a stone circle but later said to have been a tomb (Wikipedia ). There are others that are said to also be surviving Cruciform Passage Graves in the rest of the British Isles, but they lack the characteristic decoration found in Barclodiad y Gawres and the Irish tombs. The Maes Howe  at Stegness, Orkney is a similar structure that has markings on its walls.

Also on Anglesey is Bryn Celli Ddu Burial Chamber and this has a single decorated double sided stone plus some others with markings.

Part of the interior can be seen through the locked entrance gate, but you can see the inside fully if you wish, see the details below on how to gain entry. To see the inside fully, and the marks on stones, you will need to take a torch.

The structure

Barclodiad y Gawres has been been damaged over time, most of its structure being removed during its use as a stone quarry in the 18th century. Full excavation and documenting was carried out in 1952-3 by Powell and Daniel and the rock art that the tomb contained was revealed.

The mound we see is not original but a reconstruction, the original was 27m or 90ft across. This makes it around twice as far across as what we see today.

Today the surviving stones of the chamber and passage are protected by a modern concrete dome, but the original covering mound was composed of turf, contained by an edging of stones. The mound at Barclodiad y Gawres was about 20m in diameter.

The original passage was about 7m long and ran SSE to the chamber, it was a lot lower and narrower than the modern entrance way. The chamber is about 6m in diameter and has 3 other chambers, a terminal chamber and two side chambers, producing a cruciform layout. The SW chamber has been closed with stone blocking and has an unusual annexe chamber attached to it.

The smaller chambers were originally roofed with capstones, only that of the terminal chamber surviving today. The main chamber was probably too wide for capstone roofing and was probably of corbelled construction.

Analysis of remains found

This tomb was not thought to contain anything of interest and was first explored in 1952-3 producing the discoveries found.

Analysis of tree pollen found under its remnants suggests that the tomb was surrounded by thick woodland when it was constructed.

Excavation showed the cremated bones of two men, resting on the old ground surface in the SW chamber, the other two chambers had been dug into in the past and the only finds there were tiny bone fragments in the corners.

Amongst the bones in the SW chamber were found the remains of two polished bone pins, thought to be clothes fastenings, these pins are a common find amongst bone in the Irish Cruciform Passage Graves.

No burials were found in the central chamber area. A fire had been burned here for some time, and on top of its remains were the remnants of a stew. The contents of this stew included residual bone fragments and a mixture of wrasse, eel, frog, toad, grass snake, mouse, shrew and hare. The fire site was then buried under a layer of pebbles and limpet shells. Some suggest this may have bean a ritual or magical mix!

Although no direct dating evidence exists for Barclodiad y Gawres, some Irish Cruciform Passage Graves have been carbon dated to 2500-2400BC, it's therefore suggested that it is likely that Barclodiad y Gawres was constructed around this time.

Rock Art

Several of the chamber stones have marks or carvings of lozenges, zig-zags and spirals, but what makes some of them of particular interest is the way the carved shapes are manipulated and shaped with each other to form an overall integrated design. This type of large scale integration, and the elements of the decoration itself is also seen in the rock art of the great Boyne valley tombs of Newgrange, Knowth and Dowth.

The carvings here have been made by pecking small pits in the stone surface, probably with a pointed hardstone chisel. The markings on some of the stones are very faint and are difficult to make out in the gloom of the interior, some of them also seem to have a strange "surface colouration" effect that has not been seen on rock art before.

Accounts by Frances Lynch mention five carved stones and a more recent work by Stan Beckensall shows the locations of six, his additional carving being shown as located on the blocking stone of the SW side chamber.

Some who have more recently visited found six carved stones, they could not find any markings on the blocking stone indicated by Beckensall, but found an extra carving on the northern side slab of the NE side chamber. The carving was a chevron and lozenge motif of a style comparable to other carvings in the chamber.
