The monument comprises the remains of a burnt mound, which probably dates to the Bronze Age period (c. 2300 BC - 800 BC). Burnt mounds were created from debris produced at cooking sites, where fire heated stones were used to heat water. The site is located on a moderate S-facing slope to the E of the S end of the Fan Hir escarpment. It is situated to the SW of an unnamed stream, a tributary of the Nant Tawe Fechan. The low mound is turf-consolidated, but areas of blackened earth, charcoal and heat-broken stones are visible. The mound is horseshoe shaped on plan and measures a maximum of 1.5m in height on the SSE side, 12m in length (NE-SW) and 11.5m in width. There is a shallow indentation on the stream-facing (NE) side.

The monument is of national importance for its potential to enhance our knowledge of prehistoric social practices and settlement organisation. The site is well preserved and retains significant archaeological potential. There is a strong probability of the presence of evidence relating to chronology, layout, building techniques and functional detail.

The scheduled area comprises the remains described and an area around them within which related evidence may be expected to survive. It is circular in shape and measures 22m in diameter. It is centred on NGR SN 83971 19089.
