Summary

This fort is situated on the summit of Broom Hill, which is itself a spur of Cacrabank Hill. The defences display a complex history of construction, in which an oval fort was later remodelled with a massive earthen rampart with an external ditch, which was built across the interior from NNE to SSW. Subsequently, during the post-medieval period, the defences of the oval fort were first ploughed down with rig-and-furrow and then obscured by the construction of a substantial plantation bank roughly following the line of its inner rampart, and more recently still the defences on the W have been further reduced by pasture improvement outside the old plantation. In its first phase, the interior of the fort measured about 80m from E to W by 52m transversely (0.37ha), and the rampart and external ditch masked by the plantation bank, which presents an external scarp up to 1.6m in height, was supplemented around the western half of the circuit by an outer rampart and ditch, though these are heavily ploughed down and difficult to follow on the ground. In its second phase, the interior was reduced to a D-shaped area measuring 52m along the chord formed by the new rampart by 45m transversely (0.23ha); this rampart is up to 9m in thickness by 1.5m in height, and is accompanied by an external ditch 6m in breadth by 0.6m in depth. A well-defined gap towards the N end of the new rampart is evidently the entrance in the second phase, but the position of the entrance in the earlier configuration of the defences is unknown.

Investigation History

First depicted in 1857 on the 1st edition OS 25-inch map (Dumfriesshire 1861, sheet 34.10), at which time the whole fort was incorporated into a plantation extending up the hill from the E, but by 1898 the trees had been removed from the fort itself (Dumfriesshire 1899, sheet 34.10), as Alexander Curle found it when he visited in 1912 during the preparation of the County Inventory for Dumfriesshire (RCAHMS 1920, 111, no.297). While Richard Feachem included the fort in his guide book, he failed to understand the complexities of the defences and may not have visited it (Feachem 1963, 116-17). George Jobey drew up a plan in 1968 during his survey of eastern Dumfriesshire (Jobey 1971), and the OS re-surveyed at 1:2500 in 1972, and again in 1978. RCAHMS prepared a more detailed plan in 1991 (RCAHMS 1997, 133, fig 128).
