The monument comprises the remains of a defended enclosure, which probably dates to the Iron Age period (c. 800 BC - AD 74, the Roman conquest of Wales). Inland promontory forts are usually located on a ridge or spur with steep slopes on 2 or 3 sides, and artificial ramparts on the level approaches. Alternatively they may have been constructed on a promontory above the confluence of two rivers, or in the bend of a meander. Cwm Gloyn Camp and annex, occupies two spurs. The main camp is defended on the northside by a bank and ditch.There is an entrance at the north-west corner, flanked by what may be the remains of a hut. The rampart continues for a short distance on the west side but fades out as the scarp becomes steeper. Steep natural scarp on south and east. The rocky spur to the west, separated from the main camp by a steep ravine, has been fortified by a bank and ditch, 5yds long, of similar scale and continuing the line of the main rampart. Its west, south and east sides have steep natural scarps. 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.
