This promontory fort was known as Castal y Vuggane Mooar. It is located on the coast about 550 metres northwest of Ballanayre. Only a small part of this fort as shown on the 1869 1:2500 scale Ordnance Survey map now remains. The remainder has been destroyed by coast erosion and since 1869 a little more has been eroded away. At present there is evidence of cracking and slipping in the west and northwest. 


The grass covered fort, in which there is no visible trace of a dwelling, takes advantage of the natural defences supplied by precipitous cliffs to the west, north and northwest and steep-sided stream courses to the northeast and southwest leaving a narrow neck of land between these two latter features. Across this narrow neck a bank 1.5 m upper width, 1.3 maximum internal height and 3.0 m maximum external height has been constructed. A general lowering of the bank and absence of inner slopes creates a possible 2.5 m wide entrance. The ground to the southwest of the bank's southern end as shown on the 1869 map has slipped considerably. There may have an entrance at this point. There is no visible trace of an outer ditch but if there had been one it would probably have been ploughed out as the plough has been up to the foot of the bank.
