Merthyr Common

Cairn I (SO0751705038)

This Bronze Age cairn lies on a relatively level part of Merthyr Common. It measures 5.2 metres in diameter and stands 0.30 metres high with a slight dip in its centre. It is grass-covered so the make-up and structure of the cairn cannot be ascertained.

Round barrow (SO0754504975)

First surveyed in 1960, this low, grass-covered, stony mound lies to the east of the minor road, NPRN 528728, that runs down Merthyr Common. It measures 8.5 metres east to west by 6.1 metres and 0.2 metres high. When the area was surveyed as part of the Uplands Initiative by Trysor in 2012 vegetation cover was grass.

Ring cairn (SO0773904493)

This small ring cairn is one of several cairns on this relatively level area of Merthyr Common. It measures about 9 metres overall, with the ring itself being 3 metres wide and 0.3 metres high. It is grass-covered but a few stones can be seen, the southwest part of the cairn has been damaged by vehicles in the past.

Possible ring cairn (SO0779304404)

This cairn on the eastern side of the minor road across Merthyr Common measures 16.8m in overall diameter. It is defined by an encircling bank of stones 2.5m wide and 0.4m high on the west, diminishing to 1.8m wide and 0.3m high on the east. Whether a robbed round cairn or possible ring cairn is uncertain. Previously surveyed in 1960 and 1979.
A centrally placed electricity pole has been sawn off at the base. When the area was surveyed as part of the Uplands Initiative by Trysor in 2012 vegetation cover was grass and moss.

Possible ring cairn II (SO0785004250)

A turf-covered ring of stones measures 14.9m (N-S) by 13.7m overall, 1.5m wide and 0.2m high. A large amount of loose stone at the centre of the ring suggests the former presence of an internal platform though possibly caused by more recent stone dumping. Like its neighbour it is unclear whether this is a robbed round cairn or a disturbed ring cairn.

An electricity pole has previously been inserted into the inside of the ring on the south, but this has now been refused.
