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.'

Rotterdam is a major port city in the Netherlands. It was part of the European trading network that connected the Isle of Man with Continental markets, particularly during the eighteenth-century smuggling era when foreign goods from across Europe were imported into the Island for clandestine re-export to Britain and Ireland.

Earthwork enclosure. The place-name, Round Ellan, means 'round island' which gives some indication of its irregular oval shape. The site is raised slightly above the immediately surrounding land, but is overlooked by higher ground nearby to the north and east. The eastern part of the site is best preserved, with a peripheral bank rising 2m from a ditch up to 0.7m deep and 10m wide. A weak outer bank is apparent in places. Ploughing has undoubtedly reduced the height and clarity of the banks since first surveyed by the Ordnance Survey in 1869. No trace of other interior structures has been surveyed. Antiquarian opinion as to its origin was mixed, compounded by contradictory and misleading identification with other fortifications in the north of the Island, most notably the 17th century earthwork artillery fort at Kerroogarrow (see 0370), and coastal defences at Ramsey of similar date. The name 'Loyal Fort' is unlikely to relate to this site. The Duke of Wellington considered it similar to English Iron Age hillforts. A small amount of worked flint and medieval pottery has been recovered as surface finds from inside and around the site. Fundamentally, its poorly defensible topographical location make interpretation and dating difficult.

The conjectured site of a Neolithic settlement based on excavation evidence of activity in the area.

The site of cremation burials excavated by Dr Larch S. Garrad at Round Ellan.

Site of horsewalk recorded on Ordnance Survey First Edition 1:2500 (1868) at Rowany Farm. Now destroyed.

The plaque is made of marble and is engraved with the Royal Airforce crest. It was originally located in the porch of All Saint's Church (from September 2000) and in 2018 it was relocated to a wall in the Chapel of Remembrance at St George's Church, Douglas.

The site of a brewery which is shown on the Ordnance Survey's 1:2500 scale map of 1870, which names it as the 'Royal Albert Brewery'.  The building was located on Tower Street.  It is likely to have been named in honour of the visit of Queen Victoria and Prince Albert in 1847, and the latter's ascent of the hill 1km to the south, which was further marked by the erection of the Albert Tower in 1848. The brewery company was dissolved in 1923. The site is now partially occupied by a modern office building.
