Worked and unworked flint has been recovered on various occasions from Ordnance Survey Field no. 1536, Lower Ballavarkish, Arbory. The worked material is of late Mesolithic (heavy-bladed) character. The grid reference is centred on the middle of the field.

Worked prehistoric flint of Mesolithic (heavy bladed) type, including flakes and scrapers, found in Ordnance Survey Field no. 1536, Lower Ballavarkish, Arbory. The material was found towards the southern end of the field. The artefacts are in the Manx National Heritage collections, accession no. 1986-0045.

Sample of flint from Ordnance Survey Field no. 1536, Lower Ballavarkish, Arbory. The material was collected from the southern side of the field close to a watercourse, demonstrating the type of raw material potentially available in the past. The material is in the Manx National Heritage collections, accession no. 1986-0048.

Sample of worked and unworked flint and possibly utilised stones from Ordnance Survey Field no. 1536, Lower Ballavarkish, Arbory. The finds were collected from the southern side of the field close to a watercourse and are all heavily rolled. The worked flints are of late Mesolithic (heavy bladed) character, whilst the unworked flint demonstrates the type of raw material potentially available in the past. The material is in the Manx National Heritage collections, accession no. 1986-0277.

Lighthouse. This lighthouse, together with its twin nearby, was built in 1818 for the Northern Lighthouse Board to the designs of Robert Stevenson, one of the Board's most famous engineers. The two lighthouses worked in tandem, indicating to passing ships if they were in danger of colliding with the Chicken Rock nearly 2km to the south. The Stevenson lighthouses were replaced by a lighthouse on the Chicken Rock itself in 1875, after several difficult years of construction. More recently a modern light, warning of the dangers of the Calf of Man itself rather than the sinister reef to the south, was installed close to the old Stevenson towers in 1967, but this was decommissioned in 2007 as unnecessary in the modern age of satellite-enabled navigation and global positioning. The Chicken light was upgraded at the same time so that its light is visible from a distance of 21 miles. In common with many of the NLB's installations, each lighthouse was attached to a keeper's house, with adjoining garden and other basic facilities. The buildings are now maintained as nesting sites for birdlife in keeping with the status of the Calf of Man as a nature reserve and bird observatory.

The site of a group of three shieling mounds at Lower Sulby.  The field has been ploughed and there is now no trace of the mounds.

"Round Ellan" or "Loyal Fort" is a circular earthwork of unknown purpose and date. It is visible on modern aerial photographs and the present field boundaries respect its present, curving around the outside of its western and southern sides. A rim sherd of poorly glazed micaceous ware, considered to be 'medieval' as been found just inside east margin of the plateau surrounded by the earthwork and are now kept at the Manx Museum (Accession No. 1967-0125). Stone cists have been reported in the past as being uncovered whilst digging drainage trenches in the field to the east of the enclosure. The authorities given for this information were the Venerable Archdeacon J.C. Moore. M.A., Mr F. Ratcliffe, and Mr D. Quirk, Kirk Andreas.

Prehistoric flint scatter. A single worked prehistoric flint was recovered from Lynague by CH Cowley, from the 'Brooghs'. The description is too imprecise to allow a positive identification, 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.
