The site of an Iron Age roundhouse or defended settlement.  It is a grass-covered circular earthwork set in low lying land which was probably once a marsh.  It has an overall diameter of 38.0 metres and consists of a much spread bank average 9.0 metres wide surrounded by a ditch average 5.0 metres wide. The bank has an average external height of 0.7 metres and an average internal height of 0.3 metres. The ditch has an average depth from the outer lip of 0.2 metres. The ditch and bank have been ploughed out in the south-east. There is no visible trace of stonework or of an entrance.  This example compares with other roundhouses dating to circa AD200.

The site of a round cairn of late Neolithic or Bronze Age date. It was opened in 1865 and cup-marked stones were found as well as pottery sherds, a flint knife and the remains of a cremation burial. Later an urn was found nearby and reburied in the west hedge of the field,107 metres west of the monument.

A brewery formerly existed at Ballakilley.

The site of an Early Medieval keeill or chapel, thought to have been in use between circa AD 500 to AD 1000.  The chapel building was removed in 1912 and its site is occupied by a farmyard, with no visible trace of a chapel or burial ground enclosure.  The burial-ground had completely disappeared by 1860 although the Reverend William Gill recalled a visit to the site in 1828 when there were numerous flat stones protruding from the ground to a distance of 80 yards or more westwards from the church. Graves were frequently ploughed up in the area according to Oliver and a lintel-grave was seen in 1878 and another between 1912 and 1963.

The site of a probable Bronze Age barrow.

The site of an Early Medieval keeill or chapel, thought to have been in use between circa AD 500 to AD 1000.  The chapel building measured 6.5 metres by 2.75 metres internally with walls up to 0.80 metres thick and up to 2.5 metres high when recorded. The walls, built of rounded granite boulders, were removed in 1912 and its site is occupied by a farmyard, with no visible trace of a chapel or burial ground enclosure.  A doorway flanked by monolithic jambs was positioned in the south wall and there were splayed window openings in each of the four walls. The building did not appear to be of the early keeill period, but a pre-parochial treen or district church and a direct successor of the original keeill.  Bruce stated that 'A date early in the 11th century may not be too wide of the mark'.

The site of an early medieval chapel or keeill, which is not shown on the 1869 1:2500 scale Ordnance Survey map, but would be located in the field numbered 1696.  The dedication is lost and no traces of the building now remain. The site of the keeill is remembered in the name 'Chapel Field.'

A prehistoric stone axehead was recovered from Ballakilley by C.H. Cowley, from the 'Stable'.  No further details concerning the circumstances of the discovery were recorded and 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.

A tannery formerly existed at Ballakilley.
