Barsalloch Fort is a promontory fort on the edge of a cliff. It’s defended on three sides by a ditch 10m wide and 3.5m deep and an earthen rampart about 1m high on either side. The entrance to the D-shaped enclosure was to the north east.
The fort probably housed one or more large round houses for a single extended family.
Little is known about the Novantae people, and their only historical reference is a brief mention in Ptolemy's Geography. The nearby Rispain Camp was also likely a Novantae farmstead.
