1. A subrectangular enclosure 18m by 7.0m, formed of earthfast stones (having an average height of 0.8m) backed by a low bank, surrounding a levelled interior. An explicitly ambiguous monument that has only been compared to the 'Churchyard' on Skomer Island. (NPRN 305370, source Os495card; SN13SW10)

2. The site is located ESE of Carn Bica (NPRN 402817) and just to the north of a path across the mountain. It is defined by a setting of upright and fallen stones set within a sub-rectangular enclosure.

3. Survey work by Wainwright and Darvill for the SPACES project has compared the oval stone setting at Bedd Arthur to the first oval setting ('horseshoe') of Bluestone orthostats built at Stonehenge. Both settings are aligned on midsummer sunrise. Oval stone settings are a recognised form of monument in the Neolithic and Bronze Ages of Britain, but remain rare. The location of this diminutive stone setting within an earthen enclosure, in the shadow of the impressive augmented cairn and outcrop of Carn Bica (NPRN 402817) nearby, is no doubt significant.
