Dun Nosebridge is an unusual fort in the context of Islay, and to some extent the rest of Argyll, not for its position on a ridge rising from the valley floor, with a high crag forming its SE flank, but for its use of ditches in the defences, which rise in three tiers to a relatively small enclosure crowning the summit of the ridge (but see also Atlas No. 2154). Subrectangular on plan, this measures no more than 25m from NE to SW by 15m transversely (0.01ha) within a wall reduced to a bank of rubble that still stands 1.6m high above the level of the interior on the SW and considerably more externally where the flanks of the summit appear to have been scarped everywhere except along the edge of the crag on the SE. This inner enclosure stands within an outer enclosure that backs onto the cliff edge and takes in an overall area of about 0.18ha within a grass grown rampart up to 2m in height. The material for the rampart has been quarried internally and taken from an external ditch which can be traced around the SW and NW. It is unclear whether the inner and outer enclosures are contemporary, but on the W the ditch of the outer appears to have been cut into the back of yet another rampart with a substantial external ditch and a counterscarp bank; following a slightly divergent course across the spine of the ridge on the SW flank, these appear to belong to an earlier scheme, though not one that can now be traced around the NE, where elements of the defences may have been obliterated by the occupation of a later township. A gap in the circuit of the outer enclosure on the NE probably marks the position of the entrance. The interior of the inner enclosure has been cultivated in rigs.

While this is traditionally identified as a prehistoric fort, the use of ditches and scarping may indicate that most of what is visible belongs to an undocumented castle, comparable in many of its details to Dun Guaidhre, which is itself situated immediately above the parish church of Kilmeny. The topographical position is such, however, that it is likely to have been utilised whenever the need arose in the Iron Age or early medieval period. In the absence of excavation, there are neither stratified artefacts nor radiocarbon dates to provide a chronology for the defences.

First depicted on the 1st edition OS 25-inch map (Argyll and Bute 1881, sheet 209.9), it was visited in 1934 by Gordon Childe, who speculated that it was a vitrified fort, though there is no evidence of vitrifaction on the site (Childe 1935, 83, 84) and seems to have revisited the site in 1942 for the RCAHMS wartime Emergency Surveys. In 1961 a resistivity survey was carried out across the interior. It was surveyed by RCAHMS in 1979 during the preparation of the County Inventory of Argyll (RCAHMS 1984, 94-5, no.157). It was Scheduled in 1977. It was photographed from the air by RCAHMS in 2006.
