Modern watermill. The Ordnance Survey 1:2500 First Edition mapping of 1867-8 depicts a water mill at this location, annotated as 'Ballacreetch Mill (Corn)'. The building is marked on modern mapping but is completely obscured from view.

Modern mill leat. The Ordnance Survey 1:2500 First Edition mapping of 1867-8 depicts a water mill at this location, annotated as 'Ballacreetch Mill (Corn)'. A leat drew water from the stream about 230m upstream from the mill at SC3694579655, and flowed for 95m into a millpond. The line of the leat is still apparent; the grid reference relates to a point halfway along its length for indicative purposes.

Modern millpond. The Ordnance Survey 1:2500 First Edition mapping of 1867-8 depicts a water mill at this location, annotated as 'Ballacreetch Mill (Corn)'. A millpond stored water drawn off the stream at SC3694579655. The millpond was located on the side of the valley and was dammed along its W side. Its location is still apparent.

Modern mill leat. The Ordnance Survey 1:2500 First Edition mapping of 1867-8 depicts a water mill at this location, annotated as 'Ballacreetch Mill (Corn)'. A raised leat led water from the millpond a distance of 90m to the mill; a short tailrace led the water straight back into the stream just a few metres from the mill. The line of the leat is still apparent.

The site of an eary medieval keeill or chapel, which would have been in use during the period circa AD500 to AD1000.  Evidence of the chapel and lintel graves within the burial ground have been recorded here. The Ordnance Survey have noted that 'To the immediate E of Ballacregga is the site of an ancient Chapel and Burial Ground, where numbers of stone-lined graves containing human bones have been found.' The site is shown on the 1:2500 scale Ordannce Survey map of 1870 which shows the burial ground as a raised mound within which the site of the chapel is marked. The Manx Archaeological Survey noted in 1918 that the enclosure was less well defined than at the time of the 1870 Ordnance Survey map.   The Manx Archaeological Survey's investigation consisted of excavating several trenches across the mound at intervals of just under 6 metres, but these failed to find clear evidence of the chapel, instead finding 'a layer of chips and splinters of stone (which) appeared to mark the actual position of the Keeill, of which all other traces has long since been carried away.'  The survey likewise found 'one or two lintel graves and some white shore pebbles'.  It is today still possible to make out the enclosure as a combination of earthwork banks and cropmarks although the site is now somewhat overgrown in places.

Prehistoric flint scatter. A large quantity of worked prehistoric flint was recovered over the course of many visits by CH Cowley, from a site which he simply identified as Ballacregga. On separate occasions he also recovered material from a site which he refered to as 'Ballacregga, Glen Wyllin' (see PRN 3044). As it is not clear if the sites are the same or distinct from each other, they are considered and recorded separately. Cowley may have recognised the rarity and sensitivity of such early Mesolithic sites and wished to restrict awareness of their precise location. The site is thought to be in the south side of Cooildharry, in the general vicinity of SC318896. As no further details concerning the circumstances of the discovery were recorded the grid reference relates to the farmstead for indicative purposes only. 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.

Medieval chapel. The Ordnance Survey 1:2500 First Edition mapping of 1868 shows the site of a chapel and burial ground at Ballacregga farm, together with the annotation, 'Chapel & Burial Ground (Site of)'. The burial ground is shown as a raised mound, within which the site of the chapel is marked. The Manx Archaeological Survey (1918) noted that the enclosure was less well defined than at the time of the OS. The Survey's investigation consisted of several trenches excavated across the mound at intervals of just under 6m, but these failed to find clear evidence of the chapel, instead meeting with 'a layer of chips and splinters of stone (which) appeared to mark the actual position of the Keeill, of which all other traces has long since been carried away.' The site is now somewhat overgrown in places, and it is not possible to define the site of the chapel.

Medieval burial ground. The Ordnance Survey 1:2500 First Edition mapping of 1868 shows the site of a chapel and burial ground at Ballacregga farm, together with the annotation, 'Chapel & Burial Ground (Site of)'. The burial ground is shown as a raised mound. The OS particulars noted, 'To the immediate E of Ballacregga is the site of an ancient Chapel and Burial Ground....The enclosure is all that is now traceable. Authorities: Mr T Quinney; Mr R Cowin, Ballacregga; Mr W Moore, Ballavilley; Dr Oswald, Douglas; Oswald's Vestigia.'

The Survey's investigation consisted of several trenches excavated across the mound at intervals of just under 6m, which, while failing to find clear evidence for the chapel, found 'one or two lintel graves and some white shore pebbles'.

A record for an unspecified crop mark at Ballacregga.

The findspot of a Mesolithic flint scatter found in the fields numbered Plots 424 and 425 on the 1870 1:2500 Ordnance Survey map. It included a Heavy-blade type flake measuring 50 millimetres from Plot 424 and 9 flint flakes from Plot 425.

The site of an early medieval keeill or chapel, which would have been in use during the period AD500 to AD1000.  It is said to have stood on the north side of the road from Ballayolgane near the bend and is still remembered by the name 'The Old Church'. The 'Kell y Cowle' of the 1703 Man Roll refers to this chapel, which was a Cell Comgall of Bangor, the monastery which held lands in Kirk Patrick. The site is now occupied by a garden and no visible trace remains of the chapel.

Prehistoric worked flints. A number of worked flints have been recovered from Ordnance Survey Field no. 1621 at Ballacreggan Farm, Rushen. The grid reference is localised to the centre of the field.

Modern horsewalk. The Ordnance Survey First Edition 1:2500 map of 1868 records a horsewalk attached to a barn on the north side of the farm complex. The structure has now been replaced by a modern barn.

The site of a probable Bronze Age barrow which was opened in 1878, when cremation urns holding ashes were found.  It survives as a grass covered ditchless bowl barrow, measuring 22.0 metres in diameter and 0.5 metres high. It is on the edge of a natural glacis type slope.  Neolithic Ronaldsway type pottery was found when the barrow was excavated. As far as is known Ronaldsway culture is not associated with a barrow building tradition and it is possible that a Bronze Age barrow was later erected on the site of Ronaldsway activity.

Worked flints, a clay tobacco pipe stem and modern pottery were recovered in October 1988 from topsoil stripped in preparation for residential development in Ordnance Survey Field no. 1633, north of the Promenade, Chapel Bay. The artefacts are in the Manx National Heritage collections. The grid reference refers to the centre of the field.

7 struck flints were recovered in October 1988 from topsoil stripped in preparation for residential development in Ordnance Survey Field no. 1633, north of the Promenade, Chapel Bay. The artefacts are in the Manx National Heritage collections, accession no. 1988-0453/1. The grid reference refers to the centre of the field.

A clay tobacco pipe stem was recovered in October 1988 from topsoil stripped in preparation for residential development in Ordnance Survey Field no. 1633, north of the Promenade, Chapel Bay. The clay tobacco pipe stem is likely to have been the result of manuring or from the spreading of nightsoil from Port St Mary. The artefact is in the Manx National Heritage collections, accession no. 1988-0453/2. The grid reference refers to the centre of the field.

The larger example of two ditched turf covered bowl barrows within the same field. The barrow has been clipped at the base by ploughing but survive as an upstanding mound. It has a diameter of 12.5 metres and a height of 1.7 metres. There is a hollow on top of the mound, measuring 2.4 metres in diameter and 0.3 metres deep, which may be evidence that an early attempt was made to dig into the barrow.

One of two ditched, turf-covered bowl barrows within the same field. The barrow has been clipped at the base by ploughing but survive as an upstanding mound. It has a diameter of 8.0 metres and a height of 1.0 metres. There are a few small stones exposed.

Modern watermill and associated water management. The Ordnance Survey 1:2500 First Edition mapping of 1869 shows a building at the grid reference provided, together with the annotation, 'Flour Mill'. The mill stands just a few metres from the Ballaugh stream, but was powered from a millpond excavated alongside the watercourse. The millpond covered 0.3 acres, but was confined to a narrow strip of ground. It consequently extended for over 200m, but was never more than 12m wide. The main inlet to the millpond was by way of a weir located approximately 45m downstream of the humpbacked roadbridge in the centre of Ballaugh. Additional water was derived from a field drain approaching from Carmodil to the south. The bridge carrying the former Manx Northern Railway is more than 20m long so as to span both the Ballaugh stream and the former site of the millpond. The millpond extends as far as the gable of the mill, where the wheel was located. A tail race, some 125m in length, carries water back to the stream; about one quarter of its length is shown culverted under the farmyard on the OS mapping. The building was in 2017 roofless. The tail race and millpond are largely infilled.
