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.

Prehistoric flint scatter. A small quantity of worked prehistoric flint was recovered from Ballacross by CH Cowley, from a field which he refered to as the '3 o'Clock Field'. The site has not been positively re-identified, but may possibly lie in OS Field no. 1123. In the absence of definite information, 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.

Prehistoric flint scatter. A prehistoric stone axehead was recovered from Ballacross by CH Cowley, from a site he identified as the 'Edge of Pond in front of House'. The precise location has not been positively identified, but may refer to the pool (possibly a flooded clay or marl pit) at OS Field nos 2014 and 2015.

Prehistoric flint scatter. A single worked prehistoric flint was recovered from Ballacross by CH Cowley, from a field which he described as the 'Field opposite the Court'. The Court is an earthwork site located at SC26738445; OS Field no. 1106 would fit the description given by Cowley, who also describes a site in the 'Field West of Court Field' three years earlier (see PRN 3054), but in the absence of a positive identification the grid reference relates to the farmstead for indicative purposes only.

Prehistoric flint scatter. A small quantity of worked prehistoric flint was recovered from Ballacross by CH Cowley, from a field which he named 'Margher Tree Er y Chlag'.

A fine, pressure-flaked, tanged missile head found at Ballacross, Arbory. The artefact measures 90mm overall, and may possibly be exotic, although Neolithic pottery has reportedly also been found on the farm. The artefact is only located to the landholding, and no further information is known. The grid reference is centred on the farmstead. The artefact is in the Manx National Heritage collections, accession no. 1954-0629.

Neolithic or Bronze Age burial cists and pottery were discovered here when the site was ploughed by the owner J.G. Moore. The site was examined by Canon Kewley on behalf of the Manx Archaeological Survey Committee and a Neolithic Ronaldsway vessel was identified. Kermode referred to the find-spot as 'a field about 166 yards NW of house'. The pottery appears to have been a single round-headed 'cinerary urn of Clark's 'Ultimate Bronze Age' culture re-classified as Ronaldsway. It is kept at the Manx Museum, Accession No. 1954-0568.
