Summary

The site of this fort, which is known only from cropmarks, is marked by Horsburgh Castle (RCAHMS 1967, 236, no.511), a 16th-century tower situated on the summit of a low hill low down on the N side of Tweed valley at the foot of the S spur of Castle Hill. Roughly circular on plan, It measures about 115m in diameter within a ditch about 4m in breadth, and around at least the NE quarter there is also a concentric outer ditch. Allowing for the presence of an inner rampart, the featureless interior is about 0.88ha in extent. No entrances have yet been recorded.
