Larriban or Larry Bane Head is a limestone promontory rising sheer some 150 ft. above the sea in the townland of Knocksoghey, parish of Ballintoy, about a mile east of the caves recently examined by Dr. Jackson. The neck of the promontory has been cut off by a rampart and fosse about 100 ft. from its extremity. The fort thus formed gives its name to the headland, Leath Rath Ban, the Half White Fort. Before the war more than half the enclosed area and a section of the rampart had been quarried away and the original fosse materially altered. According to the report furnished by Thomas Fagan to the Ordnance Survey in 1838 the defended area measured ‘about half a rood’, and the ‘moat was on an average 23 ft. in width’. One of the workers employed at the quarry remembers that the entrance to the fort was near the centre of the rampart. It has now been destroyed. The quarrying has, however, left an instructive section through the rampart. In this section Mr. Blake Whelan found portions of a pot standing in what seemed to be a sort of kiln in the centre of the wall. The surviving portions of building here might outline the back of a guard chamber opening near the main entrance which must have traversed the wall close at hand (P in fig. I).
