Modern mill tail race.
The Ordnance Survey 1:2500 First Edition mapping of 1869 depicts a building together with the annotation, 'Corn Mill', on the right bank of the Ballaugh stream.
The tail race extended 30m NNW from the mill before returning the water to the stream. The grid reference marks a point half way along its course for indicative purposes.
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).
The apparent site of an early medieval keeill or chapel, which would have been in use during the period circa AD500-AD1000. It was located on the east side of Port-y-Vullen where a cottage now stands in the plot numbered as No. 674 on the 1870 1:2500 scale Ordnance Survey map. A Mr Cowin and others from the neighbourhood remembered seeing lintel graves ploughed up here. The large cross-slab (Manx Cross No. 69) which is now kept at the parish church appears to have been taken from this cemetery. For many years it was set on the hedge by the highroad.
The findspot of an early prehistoric flint scatter, including worked flint flakes and blades. Larch Garrad visited the site in March 1983. Findspot is referenced in the Manx Folk Life Survey.
The findspot of a Neolithic flint scatter, which included scrapers and a saw. "Slate tallies" were also found, including a "rod with Ogham-like characters".
The findspot of a Neolithic flint scatter, including worked flint flakes and blades of Ronaldsway type as well as part of a dark igneous stone axehead.
The findspot of an early prehistoric flint scatter where "prehistoric" pottery, worked stones and flints, made reference to in the Manx Folk Life Survey.
