Summary

This small fortification backs onto Tanner's Linn, which flows in a deeply cut gully draining the hillside that drops down from the W. The defences are massive for the relatively small area they enclose, barring access from the NE and NW and comprising two earthen ramparts up to 6m in thickness by 1m in height, with a medial ditch 5.7m in breadth by 1m in depth. Forming an angular D-shape on plan, with the terminals of the ramparts resting on the lip of the gully on the E and SW respectively, the featureless interior measures between 22m and 10m from N to S by 20m transversely (0.03ha). There is no evidence of an entrance and access was presumably via the escarpment forming the SE flank.

Dating Evidence

A curiously small fortification which might be better considered an earthwork castle but for the fact there is no historical context for a castle in this particular location.In the absence of excavation, there are neither stratified artefacts nor radiocarbon dates to provide a chronology for the defences.
