Roughly nine and a half metres east to west and five metres north to south, it is defined by a raised rim of earth, broad at the base and worn almost flat in places, with stone detectable beneath the sod in certain spots. The interior sits slightly sunken relative to the surrounding ground, and contains no visible features at all. Whatever happened inside this enclosure left no obvious trace above ground.

The structure sits within a wider enclosure and abuts a scarp along its western edge. A two-metre gap in the bank on the north side of the eastern end marks what appears to have been an entrance. The bank itself is noticeably worn down at the eastern end on the southern side, suggesting that edge has seen the most weathering or disturbance over time. The purpose of the building is not recorded, but its position is suggestive: a church and graveyard lie only about nine metres to the north. Rectangular earthen-banked enclosures of this kind are sometimes associated with ecclesiastical settlements, where ancillary structures, whether domestic, agricultural, or ceremonial, were built within or immediately adjacent to the main religious complex. The proximity here is close enough to invite that reading, though nothing in the surviving fabric confirms it.
