Summary

This fort is situated on a steep-sided hillock at what is now the SE end of Jackschairs Wood. Oval on plan, it measures 70m from NE to SW by 50m transversely (0.27ha) within up to four ramparts with intermediate ditches. The ramparts are largely reduced to terraces, the two inner of which can be traced around the whole circuit. The outer two are visible only on the E and S quarters, the outermost on the E a counterscarp rampart overlain by an old plantation bank, and while there is no trace of either on the steep SW flank of the hillock, they may have been ploughed out in the saddle on the NW. An entrance on the E is probably original, though its outer end has been mutilated by the insertion of a water tank into the outer ditch on the S side of the gap, but a second gap on the SE is of relatively recent date. The ground within the interior rises into a low summit around the margins of which there are traces of at least three probable house-platforms, one on the W possibly overlying the tail of the inner rampart. An evaluation trench excavated across the defences on the NE shows that the inner rampart was stone-faced, and the excavators speculated that a post-hole in the top of the inner rampart, and settings of stones on the two outside it, possibly indicated the presence of timber palisades.
