The summit of Castle Hill, which rises up on the N side of the Tweed valley above Horsburgh Castle, is crowned by a small earthwork enclosure, which occupies the site of what was probably a substantial timber fort. The walls or palisades of this fort are reduced to little more than grooves in the turf on the NW side of the stone dyke that traverses the summit, the SE half partly destroyed by the construction of the earthwork enclosure and otherwise obliterated by ploughing in the 19th century. Around the NW half the courses of the palisades are marked by two grooves set 4.9m apart, though since the site was taken out of hill-grazing into a clearing in a forestry plantation these have become increasingly difficult to trace out on the ground. They disappear beneath the dyke on the NE and SW, the outer re-emerging on the NE to be cut by the ditch of the later earthwork. The projected circuit measures about 75m in diameter (0.45ha) and there is an entrance on the NW where the two palisades were linked to create a lined passage 3.5m wide, projections of the outer palisade narrowing its mouth to about 1.8m. Within the interior a second pair of palisades set 1.8m to 2.4m apart can be seen, forming a more typical double palisade with traces of a low medial bank, but too little survives to estimate the size of the enclosure. Again, there is an entrance on the NW, but rather than the formal squared lines of the outer perimeter, here the palisades unite in rounded 'hairpin' terminals to either side of the gap. Immediately within the enclosure, lying to either side of the entrance, there are traces of two round-houses defined by shallow grooves or ditches. Evidently a much smaller enclosure, this too is cut by the later settlement earthwork, which measures about 35m from NNE to SSW by 25m transversely within a heavily robbed inner wall accompanied by an outer bank and ditch, both of which are pierced by a well-formed entrance on the ESE. Despite the ploughing that has severely reduced the perimeter on the S and W, traces of three timber round-house stances can be seen within the interior, each comprising a small central platform encircled by a shallow groove or ditch.
