An abandoned farmstead in a secluded valley in the Ceredigion uplands. It may be medieval or early modern, and only a sheepfold is depicted on the 1st edition OS County series (Cardigan. VII.8 1887).
The stone-walled sheepfold is the most obvious surviving feature (NPRN 282908). It appears to be a disused building with a walled yard on the west side. This could be a part of the farmstead, but is perhaps more likely to be a later lluest or shepherd's hut.
The remaining features are enclosure banks and ditches, difficult to follow on the ground, but clearly laid out when seen from the air. They lie within a large curving ditched and banked enclosure roughly 200m across (NPRN 282152, 282155). This is divided into smaller fields or paddocks by straight and curving banks (NPRN 282153-4). On the east side, north-east of the sheepfold, a tangle of curvilinear enclosures represents the farmstead proper with its yards (NPRN 282150-1, 282786).
The various banks would once have been crowned by hedges and orchard trees would have sheltered the farm buildings. All have long since been nibbled by sheep. Livestock would have been important to the farmstead's economy and would have been grazed on the extensive mountain pastures thay enclose the valley. There was a string of similar settlements in this and the neighbouring valley.
The antiquity of the farmstead is suggested by its inclusion, as 'Nant y Dinas', in a list of lluestau by Lewis Morris in 1744, quoting the buildings as having origins in seasonal grazing practices. In the same list is another lluest entered as 'part of Dinas' (1).
