1. Cropmark of a concentric ring-ditch feature, the inner circuit being 14m in diameter having a central (pit?) feature & an apparent west-facing entrance gap, the outer, more substantially defined circuit, about 25m internal diameter, has a north-east facing entrance gap: features represent a barrow, surviving up to 1.0m high in the 1950's: excavations, in 1986, examined ring ditches with later prehistoric burials & cremations immediately to the west & an inhumation cemetery, late Romano-British/early medieval, to the north (see Nprn310262): a similar ring ditch feature is recorded about 330m to the north-west (Nprn305836), whilst further ring ditches are known nearby at Nantsiriol (Nprn90562).
2. Geophysical survey by David Hopewell in November 2016 for Ceredigion Historical Society/RCAHMW.
'The most obvious anomaly (5) of archaeological origin corresponds to a poorly defined earthwork in the field that has been interpreted as a Bronze Age barrow. The geophysical anomaly, in contrast, is very well-defined comprising a 30m-diameter circular outer anomaly that is best interpreted as a ditch with a corresponding upcast bank on the inside. A second inner concentric circular anomaly is 18.5 in diameter and is less well defined. This appears to include discrete smaller anomalies that could be interpreted as a ring of post ?holes quarry ?pits or other cut features. This shows that the barrow is a complex and possibly multiphase structure, the possible post holes could be tentatively interpreted as a hengiform monument dating from an earlier phase. Further roughly circular anomalies in the centre of the barrow indicate additional structural elements.'

3. Aerial survey in the 2018 drought by by Jonathan Brentnall and Glyn Davies revealed two further plough levelled round barrows close by, NPRNs 424025 and 424026, demonstrating a coherent cemetery of three large barrows.
