Although scheduled as a Motte the monument is perhaps better characterized as a defended enclosure dating to the Iron Age period (c. 800 BC - AD 74, the Roman conquest of Wales). It consists of a massive single bank and ditch cutting off an eastward facing spur of land above the Nant Brechfa and a tributary stream. The bank is c 7m high from the ditch base and extends c 20m east to west. The ditch is partially rock cut and is c 5m deep. The east and south sides of the interior fall steeply, the north less so and here a hollow way approaches up slope from the north east.

The monument is of national importance for its potential to enhance our knowledge of later prehistoric defensive organisation and settlement. The site forms an important element within the wider later prehistoric context and within the surrounding landscape. The site is well preserved and retains considerable archaeological potential. There is a strong probability of the presence of evidence relating to chronology, building techniques and functional detail.

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