An 11m long bottle shaped passage grave with 6 capstones and a small oval recess towards the rear. Originally covered by a mound 18m in diameter and a peristalith. The mound has been partially restored and two capstones are supported by modern pillars.
Two layers of paving were recorded above and between which burnt and unburnt human bones, limpet shells and pebbles were found. Fragments of some 150 Neolithic and Early Bronze Age pots were also recovered as well as flint, stone tools, a serpentine ring, Gallo-Roman pottery, querns and fragments of bronze. The chamber had been sealed with a dry stone wall and also included a small slab lined cist set into the floor.
