Defended promontory.


The whole of the southern end of Langness is cut off by a substantial bank and ditch which traverses the promontory from east to west.


At its highest the bank is some 8m wide and 2m high fronted by a ditch 5m broad and 0.5m deep. In places the bank is less well defined, which may suggest that it is unfinished.


At the highest point it has a modern building, which served as an explosives store for the nearby 19th century copper mine.
