Neolithic pottery. A large late Neolithic jar was found in 1944 during construction work at Ronaldsway aerodrome. The pot was found close to another of similar type by construction staff employed levelling ground to the north of the site of the millpond which once supplied the farm mill at Ronaldsway, and slightly to the south of the (then) northern taxiway, close to one of the wartime hangar sites. The findspot was a little over 300m west of the site of the Neolithic house discovered in 1943. It has generally been assumed that the pots represented burials, but more recent discoveries of similar, earth-fast pots buried upright at Billown suggest that they may equally well have been buried for other purposes. The pot is round-bottomed with a decorated rim. It is now in the collections of Manx National Heritage, accession no. 1983-0212A.

Bronze Age pottery. A Bronze Age cordoned cinerary urn was discovered by construction staff outside the Ronaldsway Village area (PRN 0133), about 40m NW of the rectangular dwelling on the northern boundary. This estimated location would place it in the vicinity of the grid reference provided. The urn was badly crushed by lorries removing soil from the site and any remains it may have contained had completely disappeared.

Isle of Man Airport, known also by the Manx name Purt Aer Vannin, was first established as an airfield in 1928 and served as an RAF airfield during the Second World War.

A late medieval burial excavated by the Rev. E.H. Stenning in 1935.

Remains of a Medieval lead-smelting site at Ronaldsway were discovered and excavated by the Rev. E H Stenning in 1935 during the levelling of the area for the construction of the airport. The structures were based on a raised beach and covered by about three feet of blown sand, and were interpreted as a 'lead floor' and accompanying store house and probable dwelling (see sketch plan on illustration card). Finds included masses of domesticated animal bones, apparently for supplying bone charcoal to the crucibles. Two types of pottery were also found, one a coarse type and the other a domestic yellow-glazed ware, dated by the British Museum to the 14th and 15th centuries; two deposits of clay (see plan) suggested manufacture of the pottery on the site; the red clay for the production of crucibles and the fine kaolin (chine clay) for the domestic use. Studying the evidence, Mr M Jope of Queens University, Belfast, tentatively suggested that the site may have been a cupellation shop for the extraction of silver from the lead. Ronaldsway has been equated with 'Bakenaldwath', granted to Furness Abbey in 1246, 'to build a house as well for the reception of their men as for a repository for their minerals', and may relate to the excavated remains. Stennings' excavation also revealed a lintel-grave with the decapitated burial of a young person. The skull was intact but the remainder of the body appeared to have been cremated; burnt earth and ashes had evidently been interred with the skull but no recognisable bone. The mode of burial suggested a Neolithic or later date but Stenning observed that the remains of the smelting site 'were, if anything, a little lower than the base of the grave'. (This suggests that the burial may have been later than the 14th or 15th centuries possibly.)

This broken slab was found at Ronaldsway (IOMHER 0136.00) in 1935. It bears one, or possibly two, faintly scratched simple crosses. A hole has been pecked through the slab near the top.

Post Medieval gun battery. A coastal battery or fort was built at Ronaldsway in 1695 during the French Wars. In 1715, its stonework was renovated and the guns remounted. A small-scale exploratory excavation on the southern tip of the Ronaldsway peninsula revealed a masonry revetment behind an artificial embankment, the obtusely angled plan reminiscent of the early 19th century batteries at Douglas Head and Peel Castle. The excavator assumed that the layout revealed by excavation must therefore have been a further renovation postdating that undertaken in the first half of the 18th century. The site is now heavily overgrown, and any surface indications difficult to see.

Modern watermill and associated water management. The Ordnance Survey 1:2500 First Edition mapping of 1868 indicated that a waterwheel was incorporated within the farm buildings at Ronaldsway farm. The mill was powered by water supplied by a 400m leat leading from a millpond located to the north-west. The tail race led under the road and into the sea which is immedately to the east of the farm complex. Part of the farm complex, including the mill, is now demolished and the remaining buildings have been converted for other uses. The leat and dam have been infilled and now lie within the Isle of Man Airport estate.

Modern watermill and associated water management. The Ordnance Survey 1:2500 First Edition mapping of 1868 indicated that a waterwheel was incorporated within the farm buildings at Ronaldsway farm. The millpond was fed by a natural watercourse flowing from the north from the direction of Ballahick. The pond covered an area of 0.6 acres, and was dammed by a substantial embankment on the south and west sides. The millpond was connected to the mill by a 400m leat. The leat had similarly to be embanked for three quarters of its length. The tail race led under the road and into the sea which is immedately to the east of the farm complex. The leat and dam have been infilled and now lie within the Isle of Man Airport estate, though can still be traced as cropmarks.

On a slight eminence in a field immediately north of the farmhouse at Ronaldsway numerous stone-lined graves containing human remains, have been discovered. About forty years ago (circa 1826) the remains of the fence enclosing the same was removed, now leaving no traces but the levelled mound which can barely be traced. No indications of a chapel having stood there have been discovered. A number of un-orientated and unenclosed burials at a higher level were tentatively associated with the nearby Battle of Ronaldsway, 1275 AD.

A richly furnished Neolithic dwelling site was discovered here in 1943 during the wartime extension of Ronaldsway airfield, while the ground surface was being mechanically flattened. Because of the pressing need for the construction work, only a hurried salvage excavation was possible. It is the type site of Neolithic Ronaldsway settlements.

This thin rectangular slab was found during excavations at Ronaldsway (IOMHER 0133.00) in 1935. The slab is decorated with a narrow beaded border, in the centre of which is an equal-armed compass-drawn 'cross patte' within a double circular frame. Three 'tau' crosses are located in the bottom left hand corner. It probably served as an altar front, before being re-used in a lintel grave.

This rough slab was found at Ronaldsway (IOMHER 0133.00) in 1937. It bears a small pecked cross with almost equal arms on one face.

The site was defended, probably in the Norse period, on the north by a wall having a gate and sallyport, and on the south and west by a ditch and rampart with dry-built stone revetment and entrance. A rough slate cross-slab from an earlier grave had been re-used in this revetment. A long rectangular building at the northwest corner of the site and the extensive stone pavements found towards the central and east parts were apparently constructed about the same time.

More than thirty iron smelting-places, surviving as patches of charcoal and slag were uncovered, some resting on the stones of the broken-up pavements, the northwest wall of the long house had apparently been plundered to make smelter's furnaces. The slag appeared to be similar to that found on various Irish sites, and may have dated from mediaeval times, although Megaw saw it characteristic of the Norse phase of settlement.

It is believed that a keeill or chapel existed at Ronaldsway during early medieval times, probably during the 8th or 9th centuries AD. There is no evidence of its existence however.

An Iron Age settlement discovered at Ronaldsway. The earliest structures were six circular stone-based huts and remnants of others, averaging about 20 foot diameter, in some cases rebuilding appeared to have altered the original plan. The hearths were a small platform or semi-circular enclosure against the wall. Almost in the centre of the largest hut was a beehive-shaped oven built of stone and clay. The associated finds including bone pins, spindle whorls, bronze and iron implements and jet armlets were considered to date from the Roman occupation of Britain, therefore Manx Iron Age. A kitchen midden of limpet and whelk shells, bird and animal bone and broken cooking pots and storage jars was associated with the huts.

A 10-11th century rectangular slab which Kermode called Roolwers Cross which once stood on the village green at Maughold. It has not been identified in the Maughold Cross House.

A mound at the centre of this field is thought to be a natural feature.

The broken head of a cross-slab with a carved cross on each face, and a Runic inscription running up the shaft. It measures 39.4 centimetres x 23 centimetres x 8.25 centimetres thick and is kept in Braddan Church. It is of Scandinavian date and is recorded as Manx Cross No 138 (110).

This fragment shows on both faces the remains of the head of a cross. One face shows a common treatment of the head and one arm, but the pelleted bands terminate in a novel manner by uniting to form a ring to which two smaller rings are attached. Between the head and the remaining limb are two diagonal rings interlaced. The other face has diagonal rings on the arms. A runic inscription reading from bottom to top occupies the shaft and head of the cross, and continues above the left arm. It translates as, '...but Hrosskitil betrayed him in a truce, his own oath-fellow.'
