Undated burial cist. The Ordnance Survey 1:2500 First Edition mapping of 1867 marks two graves 300m ESE of Cooil Roi farm. Kermode (1930) subsequently records the graves as pre-Christian, and BRS Megaw (director of the Manx Museum 1940-57) expressed the view to a Royal Commission field inspector in 1955 that they might have dated to the Bronze Age, based on a description he had been given: the inspector could find no trace or memory of them amongst local inhabitants, nor any sign of a burial mound in the vicinity. The grid reference refers to the more northerly of the graves marked on the OS.

The site of a post-medieval gorse mill.

Modern horsewalk. The Ordnance Survey First Edition 1:2500 map of 1868 shows a horsewalk at this location. The structure no longer survives.

An antiquarian record indicates that probable Bronze Age funerary urns were found in this area, but there is no information about the date of the find or any surface evidence of a burial site.

The findspot of 10 pieces of flint of early prehistoric date.  A sherd of glazed pottery (rim or handle), possibly North Devon grit-tempered ware, was also found here.

A barrow which measured 7 metres in diameter existed here before the area was cleared for a fruit farm in the 1970s. Little trace visible of the mound now survives.

The site of a feature thought to have been a Bronze Age Bowl Barrow. It consisted of a tumulus believed to be a tree covered, ditchless bowl barrow measuring 7.0 m diameter and 0.6 m high. It was destroyed by ploughing.

A late medieval and early post-medieval "Watch and Ward" beacon or lookout is believed to have been located in this area, at "Cooildarry."   Many of the Watch and Ward posts may well have been maintained on the same site since the medieval period.

A burnt mound found by Mr Allan Skillan during a fieldwalking survey.

The findspot of a Mesolithic flint scatter including about 40 blades and flakes.

A scatter of Mesolithic flints. It includes flakes, nodules, patinated scraper. The flints are thought to be of probable Heavy-blade type.

The findspot of a scatter of Mesolithic flints, which include 8 Heavy-blade type arrowheads, 2 smaller arrowheads, 2 leaf-shaped arrowheads (1 pressure-flaked), 1 diamond shaped arrowhead, 4 flakes, 1 scraper, 1 awl, and 1 core.

A large, irregular, grass covered mound which has no clearly defined limit. The diameter of the mound is between 40 and 50 metres and it is up to 4 metres high. An excavation into the surface has shown it is composed of gravel and it is probably a natural feature.

The site of a post-medieval corn mill. The mill pond dam is shown on the 1870 1:2500 scale Ordnance Survey map but no longer survives.

Several lintel graves with human remains were found in 1894 when a drain was being cut near the summit of the steep slope, on the south side of the stream about 640 metres above the highroad where it crosses Glen Wyllin. The discovery was made within the field numbered 934 on the 1869 1:2500 scale Ordnance Survey map. No foundations or trace of walls of an associated chapel or keeill have been found.

It is thought that there is a early medieval chapel or keeill site here, within the field numbered 934 on the 1869 1:2500 scale Ordnance Survey map.  Several lintel graves with human remains were found in 1894 when a drain was cut near the summit of the steep slope, on the south side of the stream about 640 metres above the highroad where it crosses Glen Wyllin. No foundations or trace of walls of such a keeill were found.

The ruins of a former corn mill building recorded at Cooilslieu farm. The 1869 1:2500 scale Ordnance Survey map shows a dam and millpond to the east of the farm buildings.

A record for a medieval shieling to the east of Cooilslieu.

The site of a post-medieval horse engine. The horsewalk is shown on the 1870 1:2500 scale Ordnance Survey map.

The findspot of a flint scraper measuring 38 millimetres in length, found near the site of a mine spoil tip.

Modern watermill and associated water management. The Ordnance Survey 1:2500 First Edition mapping of 1869 shows a complex of buildings at the grid reference provided, together with the annotation, 'Flour Mill'. The mill complex includes the mill itself, orientated E-W, and a grain store which extends from the north side of the mill at the west end. A small annexe on the east gable probably served as a kiln; a miller's house stood just to the NE. The mill was served by a leat which extends 600m upstream to a substantial weir which draws water from the River Neb. The leat is guarded by a sluice. The buildings survive intact, except for the miller's house, which was demolished c.2000.
