The site of a feature thought to be a round cairn excavated by the Rev. Canon S.N. Harrison circa 1908. It was described as a circular chamber about 7.3 metres in diameter, partly excavated into the rock, partly dry-walled. A wide passage gave access to the chamber on the northwest side. Much charcoal and signs of burning were found inside the chamber, but the only extant artefact was a Neolithic or Bronze Age sandstone pestle of fine-grained grit which is now in the Manx Museum and described as being from 'barrow on Ballaberson' (Accession No 623). It is impossible to tell from the report or from the half buried ruins whether this was a habitation site or a passage grave. Having visited it at a later date, the Ordnance Survey concluded that it was most likely a hut site and not a passage grave. Bersu thought it was a rubbish dump.


It seems likely that this was a hut circle of the unproven Early Mediaeval Block Eary type. A Neolithic/Bronze Age pestle of fine-grained grit from 'barrow on Ballaberson' is in the Manx Museum (Accession No. 1954-0623).
