steps. The uorth gate was nearly buried in fallen stones, so that one could 

 hardly creep under its lintels ; and the other gates were shapeless gaps. The 

 walls show little batter to the east, but bulge in and out, showing traces of 

 long periods of settlement in every reach. Like the inner citadel, the masonry 

 is of good and at times fairly large blocks, largest at the north gate, the joints 

 packed with spawls. The sections next the sea have been little altered. It 

 runs in an unusually straight line to the cliff, which perhajis implies 

 that even when lii-st built it ran to an earlier edge of the precipice farther 

 to the south. It is interesting to note a similar curved wall, with two gates 

 to the uorth, and at the north-east corner as at Dun Aengusa, turning 

 abruptly and running in an almost straight line to a sea-clifl', at 

 Seafort in Sussex.' Tlie link - wall starts from the eastern part 

 with an abrupt bend a little to tlie south of the corner gate. The 

 latter is 4 feet 9 inches wide (4 feet 6 inches in O'Donovan's letter), 

 varying a little, the wall being 8 feet 2 inches tliick, and the lower . 

 three feet of the jambs are ancient. From it the gate of the citadel is seen 

 facing and about 235 feet away. Tlie space between the walls at the clilF- 

 edge is practically the same (234 feet), and is 240 feet at the middle of the 

 east section. The abattis, which clings to the foot of tiie old wall, curves out 

 from the " link," and is about GO feet out from the " bastion." The older 

 nortli-cast gate was probably some 10 feet in advance of the present one at 

 the steep avenue and slope. ( "h " on plan, p. 10.) 



Westward from the galo llic wall runs in a wavy Hue' shown as regular in 

 the two older sketcli-plans (of Petrie and O'Donovau), and so reproduced in 

 the maps used by Kabbington, Haverty, and even Dunraven. Modern steps 

 ascend to the ends of the ten-ace at either side of the gale ; an inward curve 

 is found from about 50 to 70 feet westward; the north gate (r/) at 161 feet. 

 This is peifect now as in 1878. It is 4 feet 3 inclies wide and liigli outside, 

 over 6 feet wide in tlie passage. Some of the outer jamb-stones are over 



4 feet long and a foot thick. Inside, the piers being on a slope, are (like the 

 Duter gate) of different heights (3 feet 2 inches to 3 feet 11 inches). The 

 passage is 5 feet 2 inches deep, covered (like the outer gate) with three 

 lintels, the inner over 6 feet long and 10 inches to 14 inches thick ; the outer 



5 feet 5 inches long and 8 to 9 inches thick. The width inside is most 

 unusual, and probably had a narrowing pier which bad fallen or was ignorantly

'The Quler wall of Tre Ceiri in Wales is ns irregular and, like the " link-wall," is terraced, but the 

 irregulnrity in the Weigh fort, as at Cashlaun Gar, Langough, and other rork-forts, originates in the 

 CJJtour of the gr.iund, while that of Dun Aengiua runs on an unimpeded floor of crag, the more 

 rejjular reaches of the inner wulls being alone on the rock ridges.
