A post-medieval farmhouse on Cly-Cur Farm. The farm is shown as Clougher Mooar on late 19th century Ordnance Survey maps.

Neolithic pottery. A round-based urn of late Neolithic Ronaldsway type found in Colby. The object was originally classified as a cinerary urn of Clark's 'Ultimate Bronze Age' and published in 1935. This illustrated an object bearing the Manx Museum accession no. 1954/0565, but this number refers to an object which is recorded as having been found at Ballahott, Malew, some 4km to the east. The grid reference refers to the road junction at the centre of Colby.

Modern bridge. This bridging point crossing the Colby river is likely to be of some reasonable antiquity. It lies immediately to the west of the junction with the route which follows the river valley northwards, and close to both the former Wesleyan and Primitive Methodist chapels. A smithy and watermill are recorded nearby on the Ordnance Survey 1:2500 First Edition mapping of 1868, whilst less than 300m to the west is the former site of the fairfield, all of which would have relied on good communications. The bridge is referred to today as Cubbon's Bridge.

A church recorded at Colby.

Site of medieval water mill and associated water management. The mill is first recorded in the 1511 manorial roll. The current mill building is still standing, and is recorded on the Ordnance Survey 1:2500 First Edition map of 1868 as a corn mill. Milling ceased in 1927. There are modern extensions attached to the mill, which is now a dwelling. The millpond was located some distance upstream and is now filled in.

Modern chapel. The Primitive Methodist chapel at Colby was opened in 1833, on land donated by the Kermode family. It stands gable end on to the main road through the village. The chapel closed in 1950, and now serves as a dwelling, with a modern extension on the east side.

Modern chapel. The Wesleyan chapel at Colby was opened in 1833, on land donated by Captain Watterson.

A post-medieval house in Castletown.

Undated midden. A midden of animal bones, of possibly Iron Age date, was uncovered in the course of extracting sand within the curtilage of a house being built in 1923. The sand deposit was found at a depth of 3.3m below ground level and appeared to be associated with a raised beach of not later than Neolithic date. Within the deposit were three layers of fine red gravel and small flinty stones containing remains of ox, pig, sheep and red deer, the last included a rib with signs of human working. The origin of the material was uncertain as it may be redeposited or insitu. L.S. Garrad compared the site with Perwick Cave (PRN 0055) and suggested that it might be of similar, that is, Iron Age date.
