The monument comprises the substantial remains of a group of burial cairns, probably dating to the Bronze Age (c.2300 BC - 800 BC) and situated within rough grazing on a local prominence below and to the E of the summit of Tyrrau Mawr. There are four burial cairns on the level knoll, roughly aligned on the NW, NE, SE and SW. The cairns are described individually in turn from NW to SW and have been inventoried as Carnedd Lwyd cairns A - D. The cairns are largely circular on plan and measure between 11m and 15m in diameter and up to 2.5m in height.

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

The area scheduled comprises the remains described and an area around them within which related evidence may be expected to survive. It is rectangular and measures 85m from NNE to SSW by 50m transversely.
