The monument comprises the remains of a hillfort, which probably dates to the Iron Age period (c. 800 BC - AD 74, the Roman conquest of Wales). Hillforts are usually Iocated 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. The monument consists of an oval enclosure on top of an isolated hill reaching 386m above sea level. The elongated oval is determined by the ground which falls precipitously with sheer rock outcrops along the longer sides. The enclosure appears to be stone built with material from an inner spoil ditch which can be traced irregularly on all sides. There is no apparent outer ditch. The entrance, a simple gap, is on the north side.

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.
