Summary

This fort occupies a promontory formed by the old shoreline overlooking the jetty at Downcraig Ferry. The general axis of the promontory lies NE and SW, terminating on the NE on Down Craig itself, a hillock that projects out towards the pier as a narrow spine. The defences lie on the lower ground to the SW of the hillock, comprising a single rampart with an external ditch and traces of a counterscarp bank, which have been drawn across the neck of the promontory in a shallow arc. Despite William Keddie's description of pieces of vitrifaction in 1861 (Keddie 1867, 238-9), in 2014 no trace of vitrifaction could be seen in the remains of a trench that has been dug across the defences relatively recently. The interior measures about 40m from NE to SW by a maximum of 32m transversely (0.06ha) immediately to the rear of the inner rampart. The interior is featureless and there is nothing to indicate the position of the entrance.

Investigation History

Surveyed as a topographical feature in 1856 for the 1st edition OS 25-inch map (Argyll and Bute 1869, sheet 246.6), it is first referred to about 1867 by William Keddie as a vitrified fort (1867, 238-9), appearing in many lists of vitrified forts thereafter (Christison 1898, 196, no.44; Childe 1946, 136, no.52; Cotton 1954, 72). Even in Keddie's day, it seems the defences were largely hidden by trees and undergrowth, and it is first depicted in 1964 as a rampart and ditch 1:2500 by the OS, who could find no trace of vitrifaction. Most recently John Lumley has provided a detailed record of the remains for the Atlas Project; visible exposures of the banks appeared earthen.
