A 13m x 3m x 2m wall was constructed from the Rossel Howe Cairn material (HY22SW 5) some time after the Orkney Name Book of 1880 (the ONB actually places two tumuli here). During the demolition human remains were found in a cist. At the south-east end two stones, one approx 2.3x0.6 m fallen but the other approx 2.3x0.8 m still erect, are thought likely parts of a chamber.
