Cadw's description

The following provides a general description of the Scheduled Monument.

The monument comprises the remains of a chambered tomb, dating to the Neolithic period (c. 4,400 BC - 2,900 BC). Chambered tombs were built and used by local farming communities over long periods of time. There appear to be many regional traditions and variations in shape and construction.

All that remains is a huge boulder which measures 3.2m along its north-south axis, 2m wide and has a maximum thickness of 1.2m. This is presumed to be the capstone, the supporters of which have been removed. Under the northern end are two small fragmented stones; one in particular is earth-fast and the likely remains of an upright. No remains of a cairn are visible.

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 of the presence of both intact burial or ritual deposits and environmental and structural evidence, including a buried prehistoric land surface. Chambered tombs may be part of a larger cluster of monuments and their importance can further enhanced by their group value.

The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
