Summary

The fort known as The Castles occupies the summit of a long spur dropping down NW from Crock Law and presents a complex array of defences which have been heavily robbed and distorted by later activity. The sequence of fortification is not fully understood, the defences essentially breaking down into two discrete components, namely a univallate summit enclosure and a multivallate outer enclosure taking in a larger area on the S. The summit enclosure is roughly oval and measures about 75m from NW to SE by 50m transversely (0.31ha) within a rampart about 3m in thickness. The height of the rampart has been enhanced by external scarping, while on the SW flank it adopts the crest of the outcrops to similar effect. By comparison the SE flank appears relatively weak, but this sector has been heavily disturbed by stone robbing and the construction of what may be a later settlement enclosure. The multivallate defences encircle the inner work lower down the slope, extending S down the crest of the spur and leading Roger Mercer in 1985 to speculate that, while the sequence is unknown, a primary fort had already been expanded on this side. Be that as it may, these outer defences comprise two ramparts and intermediate ditches, the outer with intermittent traces of a counterscarp bank, forming a belt up to 15m deep. Including the area of the summit enclosure, in this period of fortification the defences enclosed a D-shaped area measuring 160m along the chord from NW to SE by 80m transversely (1ha) and was served by entrances on the E, SE, WSW and NW, this last and that on the E also giving access to entrances into the summit enclosure. The entrance on the WSW is notable for the way the ramparts return and unite around the terminals of the ditches to to either side of the gap. Within the interior of the summit enclosure, and mainly disposed on its NE side, Mercer noted at least fourteen house platforms, while on the S side he recorded a ring-groove house. The S end of the outer fort is probably overlain by a settlement enclosure, on the S side of which there are a series of enclosed yards. In addition to the defences, a ditch and bank broken by a broad entrance causeway extend down the slope from the NW apex of the fort to the lip of Castle Craigs, while at its E end it crosses the counterscarp bank and the outer ditch to rest on the middle rampart. This has been described by RCAHMS investigators in 1949 as a device to restrict access to the NW entrance of the fort, and by Mercer as an annexe enclosure, but these interpretations have failed to recognise that a bank also dismounts from the middle rampart at the SE entrance, indicating that at some point, probably in the post medieval period, the perimeter of the fort was incorporated into a land boundary.
