Description

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). Twyn Llechfaen is a small univallate hillfort, which is defensively sitauted on a prominent natural hillock offering commanding views of the surrounding area. The hillfort is bounded by a single rampart which stands up to 4m in height. The interior of the site measures 90m NW/SE by 63m. The hillfort was subject to excavation by H.N. Savory in 1959, which revealed the presence of an outer ditch the material from which had been used to construct the bank. Sandstone revetment was also identified, as well as evidence for a possible structure on the W side of the entrance. Trenches excavated within the interior of the hillfort revealed a sub-rectangular hut floor near the centre of the site. Finds included pottery of 3rd/4th century BC date, slingstones, animal bones and an iron object.

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.
