The findspot of an early prehistoric flint scatter.  Mesolithic Heavy-blade or Bann type material has been found in this area on separate occasions. They include a single 'Bann' missile head (Manx Museum Accession No. 1954-1148/317) as well as a stray 'Bann' flake from the Cronk ny Merriu excavation (Manx Museum Accession No. 1971-0016/17).

The findspot of an early prehistoric flint scatter which includes flakes and worked flints.

The conjectured site of an undated fort based on the identification of a "broad wall" on an annotated 1:10560 map. No evidence of such a fortification has been recorded.

The site of a post-medieval horse engine.

The findspot of a flint scatter of early prehistoric date found in a local sandpit, comprising 3 flakes.

The remains of a damaged Bronze Age bowl barrow survives here, represented by a flat topped grass covered ditchless mound, which is the southeast quarter of the barrow. It is bounded in the north, northwest and west by modern hedge banks and elsewhere by a stone retaining wall.  It has measurements of 11.0 metres east-west by 8.0 metres north-south by an average height of 1.1 metres. There is no trace of stones. There is no visible trace of a cist or the barrow in the adjoining fields which are grass covered.

A possible barrow existed in this area, where a flint axehead and an urn were found.  P.M.C. Kermode recorded  'Sites of Tumuli near the avenue to Begoade house. One about 40 yards (the other 200 yards) SW of the house in a field called Cronk ny Urn. Flint found and Urn since broken and thrown away'. It was also recorded that  'Mr Corkhill told me a larger one (flint axe) had been found in his Father's time, along with pottery, in a field since called 'Cronk Urn''.

The findspot of an undated urn found at the quarry on The Cronk, to the east-notheast of the "stone cists" found south of the parish church.

The site of a "Chapel and Burial Ground" is marked here on the Ordnance Survey's 1:2500 sclae map of 1869.  It represents the site of an Early Medieval keeill or chapel, thought to have been in use circa AD 500 to AD 1000.  All trace and remembrance of the keeill had disappeared by the time it was visited by an excursion of the N.H.A.S. in July 1899, who reported it as 'completely obliterated by the plough'.  Kermode lists the site and adds 'Lintel graves found by 'sappers and miners'.  The site was also visited by J.R. Bruce in 1963-64 who stated that the site was at the highest point of a slightly sloping field, but it was not possible to detect any surface features in the area which was covered by permanent pasture.

The site of a mound which is thought likely to be a natural feature. It has never been excavated and was recorded as a ditchless mound in a field under root crops. Its diameter is 45.0 metres and its height to the north is 2.0 metres.

This was the site of an early medieval chapel or keeill, thought to date to the period AD500 to AD1000. The place was still remembered by local residents as recently as the 1860s but is not shown on the 1869 1:2500 Ordnance Survey map, as it had evidently been lost by that time. Mr Crellin thought that the high road had been constructed through the site of the keeill. It was reported that "numerous urns" were found in the area, but these may have been associated with prehistoric burials in the vicinity rather than a keeill.

It is thought that a Bronze Age funerary barrow existed here until the mid-19th century when the construction of a new road saw the mound removed, with a number of "urns" being revealed in the process.

Hillfort. Cronk Sumark sits near the entrance to Sulby Glen. The hill rises abruptly from the lowlands and commands extensive views. The sides of the hill to the north and west are nearly precipitous and artificial defences are therefore focussed on the south and east slopes. The main defences are two banks which start at the NE corner of the hill and encircle its east and south sides. The inner bank creates a broad terrace below the easterly of the two summits of the hill. The outer bank, of rather smaller scale, is almost concentric with the inner bank. A former track leading from Grangee farm (at the foot of the hill to the east) to the 19th century quarry below the westerly summit may overlie an outermost bank. The trackway may mask an earlier entranceway leading up from the SSW. The top of the hill is separated into two summits. The westerly hilltop has been truncated by quarrying, and is not clear whether any archaeological features existed on its now craggy summit. The eastern summit is more spacious, and is surrounded by a substantial rampart which rises in places to 2m in height and encloses a level area about 25 by 20m across. A slight mound near the north-eastern corner may represent the remains of a defensible entrance. The rampart is constructed from earth and stone, several samples of which appear to have been burned; it is not clear if this was a deliberate act of construction or destruction. Between the summits, the bedrock has been excavated to form three ditches running from north to south. Two of these are discontinuous and are spanned by a causeway of bedrock, but the third, adjacent to the westerly summit, is deeper and has no such interruption. It is possible that this ditch, protecting the westerly summit, was spanned by a timber structure which has left no obvious remains. Local tradition has it that the western summit was used as a place of execution, and that during the later medieval period the hill served as the meeting place for a church court. It has also been suggested that the name, rather than indicating 'Primrose Hill', should instead be translated from the Manx as 'hill of refuge'.

Medieval execution site. Local tradition asserts that the western summit was used as a place of execution.

Local tradition has it that during the later medieval period the eastern summit served as the meeting place for a church court.

In 1953 the site of a possible ploughed out Bronze Age barrow was reported by Mrs J. Quilliam.  It was described as a ditchless, grass-covered, sandy bowl barrow with a diameter of 15.0 metres and a height of 0.4 metres.

A site where lintel graves have been reportedly found, perhaps indicating the presence of a burial ground. The record is based on an annotation on a map of antiquarian observations kept in the Manx National Heritage Library and Archives: there is no other tradition associated with the area to confirm this. The grid reference relates to the centre of the area in which the annotation is recorded.

The findspot of a scatter of Mesolithic flints. They are kept at the Manx Museum.

Antiquarians suggested that the natural hillock at Cronk Urleigh was a medieval place of assembly. This romantic theory has been discounted in modern times however, and has been explained to be the result of the misapplication of place names.  'Cronk Urleigh' is a natural feature.

The site of a round house which was subject to a small-scale emergency excavation by Dr Larch S. Garrad in 1984-1985. Evidence of multi-phase activity was found, including a Bronze Age cremation burial, an Iron Age hut and glass 'toggle' beads.
