Summary

This promontory work occupies the bluff overlooking the E end of Gilknockie Bridge and in the early 20th century was believed by some in the locality to be the site of a tower constructed by Johnny Armstrong of Gilknockie (Hyslop and Hyslop 1912, 350-1). While there is no evidence of a tower at this location, which has been heavily disturbed by quarrying and the roads and tracks approaching the bridge, a massive earthwork has been drawn across the neck of the promontory on the ENE, comprising an earthen rampart 7.5m in thickness by 1.8m in height with a broad external ditch. The triangular interior, which falls away precipitously on the NW and S, measures 61m from NE to SW by a maximum of 36m transversely (0.1ha) immediately to the rear of the rampart. Midway along the rampart there is an entrance with a corresponding causeway across the ditch. The character of the visible earthworks suggests that this is probably a medieval castle and it may have been the caput of the barony of 'Bryntallone' or 'Bretallach', which became redundant when its lands were granted to the priory of Canonbie (RCAHMS 1997, 196).

Investigation History

First depicted in 1857 on the 1st edition OS 25-inch map (Dumfriesshire 1862, sheet 53.12), it was visited in 1915 in the final stages of the preparation of the County Inventory for Dumfriesshire (RCAHMS 1920, 30, no.50). It was resurveyed by the OS at 1:2500 in 1970 and revisited in 1973. It was revisited by RCAHMS in 1980. It was Scheduled in 2009.
