The monument comprises the remains of a substantial hillfort, which probably dates to the Iron Age period (c. 800 BC - AD 74, the Roman conquest of Wales). Hillforts are usually located on hilltops and surrounded by a single or multiple earthworks of massive proportions. Hillforts must have formed symbols of power within the landscape, while their function may have had as much to do with ostentation and display as defence. This formidable defended settlement is in a prominent position, protected by a natural cliff and very steep slope around the west, south and east. On the north and north-west there is a massive inner rampart interrupted by a well-defined inturned entrance on the north-west. Beyond the inner rampart on the north is a deep ditch, a second bank and an outer ditch. The interior is very uneven, but does not seem to be disturbed. Another strongly defended settlement is situated some 350m to the north-north-east.

The monument is of national importance for its potential to enhance our knowledge of later prehistoric defensive organisation and settlement. 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 site forms an important element within the wider later prehistoric context and within the surrounding landscape. Its proximity to the defended settlement to the NNE adds to its interest.
