Described as a group of three Bronze age cairn, one of which was excavated by local men in in 1938. They reported finding a medieval burial, in one barrow, with traces of plate armour with the bones. This find cannot be confirmed and subsequent investigations by the Ordnance Survey in the area failed to identify the barrows (DAT 2003) From newspaper cutting in RCAHMW archive: "What appear to be human bones and a portion of a suit of plate armour have been found on a tumulus on Disgwylfa Mountain, Ponterwyd, near Aberystwyth. The discovery is interesting from an historical and archaeological point of view, as it would seem that the burial took place in or about the fifteenth century.

Mr. J. W. Smith, headmaster of Ingle-ton-road Schools, Ward End, Birmingham, related to me to-day the story of how he found these relics. He is keenly interested in local history .and legend and for the past 14 years has spent his holidays with his wife at Ponterwyd.
A year ago he found on Disgwylfa Mountain an urn, now in the National Museum of Wales, which has been described as one of the finest discoveries o£ its kind made in Wales. In the same barrow he came across two canoe coffins of unusual type with cremated bones.
Both the urn and the coffins were declared by the National Museum officials to be specimens of early British culture of the period 1600 B.C.

As he displayed his latest finds to us, Mr. Smith explained why he was undertaking the task of exploring the hills surrounding his pretty home-made bungalow at Ponterwyd, which he has namad Awel-fryn.

"I should like to see a local museum established as a centre of attraction for students and others,' he said. "I hope my efforts will be an impetus to- the inhabitants of this area to take a greater interest in the historical importance of .their neighbourhood."

Another discovery in the Ponterwyd district is that made on Dinas, where, a series of three stone mounds, known locally as " garns," have for many years been of local interest:

It was at first believed that these collections of flat slate slabs were carted to the summit of Dinas to serve as points of vantage in the first ordnance survey in the latter part of the eighteenth century. Mr. A. Jenkins of Ponterwyd, attempted to disprove this theory by removing the stones which formed a tunnel towards the centre of one of the mounds.

His work was continued by Mr. Smith, assisted by Mr. Glyn. Edwards, Dinas Farm, and this revealed a stone cyst where Mr. Smith found the human bones and a plate of armour.

We decided to visit the Dinas, and a small party, which included Dr. S. R. Haselhurst, headmaster of Evesham Grammar School, and his son, Mr. J. S. Haselhurst, both of whom. are on holiday at Ponterwyd, was led by Mr. Smith.

The climb seemed endless, and on reaching our destination Mr. Smith pointed out the cyst and the soft earth near the surface of the stone mound where he made his latest discovery.

From the position of the remains," he said, "it could be assumed that the body was buried in a hurry, probably after one of the many fierce battles said to have been fought on Plynlimon in the Middle Ages." . R.S. Jones, Cambrian Archaeological Projects, 2004
