Mynydd Rhiw

Barrow / Cairn Cemetery


There are four cairns in a linear group towards the northern end of the summit ridge of Mynydd Rhiw. A further cairn was destroyed by the erection of the radio transmitter to the west of this group.

Coflein details, south to north:
Cairn I (destroyed) (SH2297229496)

No trace of this cairn survives; it was removed during the construction of a radio station and mast. In 1939 it was described as being 18m in diameter.

Cairn II (SH2325029497)

Cairn situated on a prominent SW to NE aligned ridge of volcanic rock crossing the summit of Mynydd Rhiw.

An impressively sited cairn, comprising a max 17m diameter spread of stone that falls away down the hillslope. Within this spread there is a 6m diameter core some 1.5m high, within which a modern structure/shelter has been constructed.

Cairn III (SH2327429600)

The cairn is situated just 9m south of and below a more prominent cairn (Cairn IV). It comprises a low spread of stone 14m in diameter and 0.5m high into which a recent structure has been constructed. Around the north-west edge of the cairn, a series of stones may represent the original kerb.

This cairn appears to have been used as a sighting point on the line of the Parish Boundary. The boundary runs up and changes direction at the cairn and there is some suggestion that parts of the parish boundary may have earlier antecedents.

Cairn IV (SH2327829625)

The cairn sits on a high point of the ridge and is one of the largest, comprising a wide spread of stone 23m in diameter that is partly mixed with natural scree. Within this spread a 10m diameter pile stands up to 3m high and has a number of modern structures/shelters constructed in it.

Cairn V (SH2330429679)

The cairn comprises a spread of stone 12m in diameter, of which some material has fallen down the slope. The cairn stands up to 0.7m in height and is comprised sub-angular stones 0.2m to 0.4m in size. A small modern cairn has been constructed onto this cairn.
