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. This is a contour fort, which measures half a mile long and a quarter of a mile wide at its widest point. It crowns one of the Clwydian Range and is surrounded by a single bank, though the east side is defended by an additional bank. On the steeper slopes it lacks an outer ditch. There is an elaborate entrance at the south east point, the rampart being incurved, and two others in the north east sector.

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.
