Scobaun, Poetadoon (ibid.). — This is also a fine example of the small 

 high-banked promontory forts. They are so rare up the west coast, from 

 Cork northward, that I can only name Lissadooneen and perhaps Faillnamna 

 in Kerry, Dundablen in Co. Clare, and Bunnafahy (Achill) in Co. Mayo. 

 It is strange that so much labour was expended to fortify such small head- 

 lands. The fort is probably of considerable age. The sea has cut along a 

 line of cleavage, leaving the inner rampart intact, and, at the northern end, 

 a few yards of the fosse and outer ring. The headland is about 93 feet 

 across; the works are boldly convex, and 105 feet round the summit. The 

 outer ring is hardly traceable along the south segment of the fosse ; it is 6 feet 

 wide. The fosse is from 12 feet to 18 feet wide, and 6 feet 6 inches deep. 

 The inner rampart is 24 feet to 6 feet thick, and from 6 feet to 10 feet higher 

 than the garth, and 16 feet to 19 feet outside, above the fosse. It is remark- 

 able among promontory forts for having the inner face terraced by revetments 

 of small, well-laid masonry, forming berms or terraces 3 feet by 3 feet, 4 feet 

 by 3 feet, and 3 feet by 6 feet along the northern segment.
