The monument comprises the remains of a ring cairn, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated within open moorland on a level terrace on the SW-facing slopes of Castle Bank ridge. The well-preserved ring cairn is circular on plan and measures about 11m in diameter over a stony ring bank spread to about 2m in thickness and up to 0.3m in height. The interior is level and largely stone free. The ring cairn is situated in a classic location, with wide views all around, except on the NE where it is overlooked by the higher ground of the ridge.

The monument is of national importance for its potential to enhance our knowledge of prehistoric burial and ritual. The monument is well preserved and is an important relic of a prehistoric funerary and ritual landscape. It retains significant archaeological potential, with a strong probability of the presence of both intact burial or ritual deposits and environmental and structural evidence.

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