The monument consists of an extensive settlement, stretching from Tan-y-Garth at the NW, for about 250m towards Cil-Twllan. It could represent occupation from the Iron Age or Romano-British period (c. 800 BC - AD 400) through to medieval times (c. 1066 -1540 AD).

Just S of the sheep folds at Tan-y-Garth are 2 or 3 circular features, perhaps hut foundations. On the rocky terrace above this, to the SE, are 2 rectangular platforms and foundations scarped into the slope and associated with ruined field or paddock boundaries and a circular enclosure. Further to the SE, in the SW corner of a small rock-strewn enclosure are the remains traditionally known at Eglwys Cil-twllan. These consist of a building lying on a platform which is dug into the hill on the NE and is built up on the SW side. A single course of large boulders remains. The doorway was in the centre of the NW side and outlying stones may denote the previous existence of a porch, a terraced track approaches from this side. To the N and NE, in the same enclosure, are three level areas which may represent building platforms. The remains of another rectangular platform scarped into the hillside lie in wet, marshy land 45m to the SE of Eglwys Cil-twllan.

The monument is of national importance for its potential to enhance our knowledge of settlement organisation. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
