Prehistoric  

The following provides a general description of the scheduled monument. 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 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. The remains consist of an incomplete circuit of earthwork bank and ditch. These defences are best preserved and most fully formed on the west and north sides with a rise of about 2.5m from the bottom of the ditch to the top of the bank. Animal erosion in places exposed up to seven courses of dry stone retaining wall. The defences are absent on the southern 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.
