Thought to be a medieval castle motte, set on a relatively level shelf on north-west facing hillslopes: a steep-sided moated mound, about 36m in diameter & rising 6.1m to a summit area some 24m in diameter, dished up to 1.0m deep: an excavation made in the centre of the summit, 'some years' before 1931, reportedly cut through alternating charcoal & soil layers, one of the upper charcoal layers containing pot sherds &'thin bones'. (Coflein–ref. Jones)

Pencastell Motte is still in a very good state of preservation. Standing up to a height of 6.1 metres, with a partly water filled ditch 1.5m - 2 metres deep.

The motte is densely covered by trees + brambles and has a modern path cut into its south-eastern side, running down to a field immediately SE of the Motte. (Dyfed Archaeological Trust HER)

Gatehouse Comments

Motte with partly water filled ditch, bailey entirely ploughed out but seems to been to the west of the motte.
