Worked prehistoric flints. Worked flints were recovered as a result of fieldwalking in OS Field 1458 / IoMG Field 414187, in 1987. The material was collected on a separate occasion to the finds recorded under PRN 1930, are of Neolithic or Bronze Age character, and were found towards the more easterly end of the field.

Late Mesolithic worked flint. Prehistoric worked flints recovered during fieldwalking (OS Field 1458 / IoMG Field 414187) in 1987. The material is of heavy-bladed character.

Modern lead mine. The Ordnance Survey First Edition 1:2500 map of 1868 records "Lead Mines" at this location. The map shows a single building, probably an engine house, immediately to the east of a shaft, and north of a spoil heap. The grid reference relates to the mineshaft. Modern mapping implies that more than one shaft is present.

Modern lead mine. The Ordnance Survey First Edition 1:2500 map of 1868 records "Lead Mine" at this location. The buildings marked on the map would appear to be agricultural, but a spoil heap is marked at the grid reference provided.

The site of a post-medieval horse engine.

The apparent site of a "possible grave" recorded by P.M.C Kermode. No further information is recorded, but its proximity to the cross-slab PRN 0753.00 may indicate an association.

The reported site of a possible barrow. The field is grass covered and there is now no trace of a barrow. In the area are several geological formations which vaguely resemble barrows however.

The site of a post-medieval fulling mill.

The site of a post-medieval millpond dam.

The site of the burial ground of an early medieval keeill or chapel known locally as 'the old church'. A cottage now stands here and in the garden, overlooking the stream, many lintel graves have reportedly been found.  The site is located within the field shown as Plot No. 2206 on the 1870 1:2500 scale Ordnance Survey map.

Prehistoric flint scatter. A small quantity of worked prehistoric flint was recovered from Ballacosnahan by CH Cowley, from a field which he referred to as the 'Field above the House'. This would appear to relate to OS Field no. 0281, centred at the grid reference provided. The antiquary Charles Harry Cowley was an avid collector of worked flint and coarse stone artefacts revealed by agricultural activity, mainly on farms located around Peel, and occasionally from further afield. He was active from 1900 until 1943. His entire collection of artefacts, together with a daybook cataloguing his discoveries, was later donated to Manx National Heritage.

Prehistoric flint scatter. A small quantity of worked prehistoric flint was recovered from Ballacosnahan by CH Cowley, from a field which he referred to as the 'Germans' Field'. The finds were made in 1920 and the field may have been named in reference to the use of labour from the nearby WW1 internee concentration camp at Knockaloe.

Prehistoric flint scatter. A substantial quantity of worked prehistoric flint and coarse stone tools was recovered from Ballacosnahan over the course of several visits by CH Cowley, from a location which he refered to only as 'Ballacosnahan Top Fields'. The location appears likely to relate to OS field nos 323 and 571, and the grid reference refers to a central point within this area for indicative purposes.
