This stone stands just across the track to the south of the barrow. There’s nothing on the HER to suggest it’s old, but the edges have been smoothed over time in a way that suggests it’s been exposed for a long time, one way or another.
Seen from the enclosure (probably medieval or later) lying across the track to the west.
The vegetation on the flanks of the barrow looks to have been strimmed.

Several cairns of various types along the Mynydd Bach ridge. North to south descriptions:
Mynydd Bach 2/Maesycymmer cairn (ST1703292614)
GGAT description:
A robbed cairn 16m in diameter with a few stones protruding through its grass covered surface. It is 0.6m high on the E side and 0.2m high on the W side. There are shallow depressions in the top and sides. No cist or retaining circle is visible.
Maesycymmer Ring Cairn (ST16979246)
Not shown on the OS map. GGAT description:
A cairn 23m in diameter with a maximum height of 1m. A fragmentary rim is visible but within the rim mutilation is extensive and the mound is of irregular height and plan. No cist is visible. The cairn is partly grass covered and is in the path of an encroaching coal tip.
Mynydd Bach 1/Ynysddu/Pen-rhiw cairn (ST1678991977)
GGAT description:
The cairn is situated on the top of the ridge, in a grass field. It is turf covered, c.13m in diameter and 1m high. In the middle two slabs of a cist are showing, 1m and 0.75m long, in a depression, 1.5m by 1.5m and 0.7m deep. Some small stones are lying in this depression, and some larger ones are lying on the surface. On the northern side is a disturbance hollow, turf-covered, 2m in diameter, and 0.5m deep, with a few large stones lying in it. To the W of the cairn is an area of quarrying.
Pont Bren Gwyn ring cairn (ST1708091940)
Not shown on the OS map. Coflein description:
On a narrow strip of open land between field walls and a track over the mountain lies the remains of a ring feature. It is defined by an arc of stony bank, open on the W side, measuring 2m-3m wide and 0.5m high on the outer E side but only 0.25m internally. The overall diameter of the ring would have been about 10.5m.

Looking northwest towards the Brecon Beacons. The monument looks deceptively intact from this angle.
Looking north over the concrete roof of the building, over Ebbw Vale towards the limestone plateaus of Mynydd Llangatwg with the Black Mountains beyond.
The steep drop to the Ebwy valley from the eastern side of the cairn. The loose material is a mix of stone from the cairn and bits of brick and cement from the building stuck into it.
The blighted northern side of the cairn, with brick and concrete insertions. Motorbike tracks cut the edge of the mound in the foreground, although mercifully they don’t go right over the top.
The southwestern side of the mound. Looking across the Ebwy valley to Mynydd Carn-y-cefn. The cairn on that ridge is at the left-hand end, right above the steep escarpment prow.
Y Domen Fawr from the lower part of the ridge to the north. The cairn is visible on top of the hill. From this angle, I’m reminded of The Whimble.
The mound on Bwlch y Garn. GGAT suggest this is a clearance cairn. It looks to have been built on a natural rocky outcrop (seen on the left) and it has elevation above the surrounding ground surface, which suggests more significance than mere clearance would warrant.
The fine placement of the cairn right on the edge of the drop can be best appreciated from Bwlch y Garn to the north.
The fine view northeast to Pen-y-Fal (The Sugarloaf). The top of Ysgyryd Fawr can just be seen over the top of Mulfran, the dark escarpment to the right of centre, and the summit of Blorenge peeks over the ridge further to the right.
Looking northwest over Tredegar towards the cloud-shrouded Brecon Beacons.

(22.1.2022) Leaving Ebbw Vale town centre behind me after my descent of Mynydd Carn-y-cefn, I carry on with the second half of my horseshoe walk of the two ridges either side of the Afon Ebbwy.
My route follows roads into the suburb of Briery Hill, then from a sharp bend turns onto a track which will take me onto the open hillside. It’s still bitterly cold, with ice lying in the ruts of the track untouched by the early morning sun that quickly got smothered by the afternoon’s cloud.
Ahead of me to the south Y Domen Fawr rises with the appearance of a steep, conical dome. It’s partly an illlusion, as it’s actually the northern end of a higher section of ridge, but from here it looks like a solitary lofty peak.
Somewhere off to the southwest I can hear the buzz of off-road bikes. I’m hoping to avoid anymore tire damage after the mess encountered on the Mynydd Carn-y-cefn cairn.
My mind is soon distracted by the steepness of the climb and my protesting leg muscles. At length I crest the hill and the parlous state of Y Domen Fawr’s own monument becomes apparent. It’s a very large mound, but its size and prominent position obviously attracted the attentions of the British Army, who decided it would be a brilliant idea to insert a brick and concrete emplacement into the northern side of the monument. To add insult to injury, a sturdy wooden bench has now been added to the top of the mound. Next to the bench, a rusty iron rod has been draped with blue and yellow ribbons, fluttering in the light breeze. In a couple of weeks’ time, Russia will invade Ukraine, although I don’t know that yet.
Ironically the obstacles caused by brick, concrete and wood may have spared the surviving mound the threat of motorbikes, and the tire tracks here just about skirt the western edge of the mound.
I decide to make the best of the bench and stop for my sandwiches. While I’m finishing off, I’m joined by an older gentlemen who tells me he’s from Nant-y-Glo, a couple of valleys away. We have a chat for a while, he tells me that the brick building was used for radio transmissions at one time. I point at distant hills and talk about Bronze Age barrows and how much I like visiting the Valleys. I enjoy his company and our chat; the “Covid years” have suspended these sort of chance encounters and it’s nice to re-engage again.
As he leaves, the sun finally comes out and I get some nice winter light for a while. Eventually I head south along the ridge, before deciding to head straight off the escarpment down the precipitous slopes to the east. A scramble and tumble through bracken, scrub and quarried areas, this may not have been especially wise but it is quite fast! Eventually I regain roads and head back to Ebbw Vale Parkway for the train back to Cardiff. It’s been absolutely brilliant to get back into the South Wales valleys after such a long time – I won’t be waiting so long for a return.
A hot, sunny trip involving a horseshoe walk around Mynydd Coety and the ridges above Blaenavon in May 2021 reminded me how much I have been neglecting South Wales recently, but even so it has taken me until the turn of a new year (22.1.2022) to act.
It’s freezing cold when the near-empty train drops me at Ebbw Vale Parkway station, a hard frost rendering the pavements slippery. The sun is shining though, and as I start to make my way uphill on a zigzag path to Waun Lwyd, there is a great view of Y Domen Fawr across the valley westwards. If my legs permit, I hope to get up there later today, but it looks like a long walk to get all the way around the head of the valley and up the other side.
First things first though, I already have one steep hill to negotiate above me. The scruffy path climbs to a reservoir, where further four-wheel vehicle access has been blocked by huge stones. Sadly two wheel vehicles are not prevented, as will become apparent later.
Above the reservoir, the escarpment climbs steeply and I’m soon feeling pretty warm underneath layers of clothing. I’m relieved to make it onto the top of the ridge, although the path becomes increasingly lost in heather and grassy tussocks. From the south a big cloud-front is now moving overhead, and my hopes of a lovely blue sky are quickly smothered.
Still, it’s great to be back up on the ridges again. The views are fine despite the overcast sky. My only company as I make my way across the heather to the summit trig is a herd of ponies, wary of me but no trouble. The trig is placed on the highest point of the ridge, giving good long views but absolutely no good views of the valleys either side. For that you need to head to the edges of the escarpments either side. It’s not a great place for a Bronze Age cairn and the builders of such monuments have clearly taken this to heart.
To find what I’ve come up here for, I have to keep heading north along the ridge. Unfortunately the damage caused by motorbikes now becomes apparent; a broad black line cutting through the surface vegetation into the peat below, stretches all the way to the end of the ridge and the solitary cairn at its end. The tracks sadly continue onto the ruined monument itself, no respect given here.
In truth the cairn is in a pretty sorry state even without this latest desecration, a ragged rim of earth and stone around a central scoop, the southern edge almost down to ground level. However, the views and location make up for the state of the archaeology. A sweeping panorama stretches from Y Domen Fawr across Ebbw Vale to the west, taking in the Brecon Beacons (mostly hidden in the cloud), the limestone plateau of Mynydd Llangatwg and Mynydd Pen-cyrn, with the Black Mountains behind, and the solitary peak of Mynydd Pen-y-Fal (The Sugarloaf) beautifully framed by valleys to the northeast, then across eastwards to Mynydd Coety with Blorenge peaking out beyond. A superbly placed monument, for all its unloved, battered state. It’s 11 years and a handful of days since I wandered across the limestone of Twr Pen-cyrn and got my first long distance views of Mynydd Carn-y-Cefn. It’s taken far too long to get up here.
I stop at the cairn for a good while, partly hoping the cloud will lift but it’s not happening. Eventually I follow the scarred tracks steeply down to the flat area below, named Bwlch y Garn (Pass of the Cairn) on the map. At the north-western end of this flat area is another irregular mound. GGAT dismiss this as a clearance cairn and they may be right, but the setting would be excellent for a Bronze Age monument. From here the definite article is clearly visible on the lip of the escarpment rising behind me to the south.
I head off downhill via crumbling paths to Ebbw Vale town centre, a drab place on what has become a grey day. But I’m not stopping, I have another hill to climb, and set my weary sights upwards on Y Domen Fawr.
The cairn is large enough to be visible on its hilltop with the naked eye from across the other side of the Ebwy valley. Seen from the southwestern ridge of Mynydd Carn-y-cefn.
The eastern profile of the Black Mountains, from Pen-y-Fal at the southern end, to Hay Bluff/Pen-y-Beacon at the northern end. Pen y Gadair Fawr is the unmistakeable prominent peak just slightly off centre. The viewpoint is the Malvern Hills in Worcestershire, about 40 miles away to ENE.
