360 TREGONNING HILL AND ITS SURROUNDINGS. 



hundred yards tlie interior vallum rises in two tiers to the height 

 of fourteen feet. The lower part is of massive stone work, whilst 

 the upper is composed of stones and earth commingled. Each 

 vallum shows admirable specimens of walling, wonderfully pre- 

 served, in marked contrast to neighbouring modern work, which 

 is already falling down in places. Below a sally-port on the east 

 is an excavation, apparently following the course of the foss. 

 The diameter of this camp is 240 feet. The site only of another 

 camp exists in a field in Gframmar Polly's Lane tenement, whilst 

 remains of another are to be discerned near the road from 

 Tregonning to the top of the hill on the N. W. side. 



The western summit of the hill is crowned by Castle Pencair, 

 a circumvallation of vast proportions, which has been often 

 described. 



On the N.W. of the large camp Castle (Pencair), are the 

 foundations of two hut-circles, sunk deep in the earth. "Within 

 this camp may be distinguished the foundations of fifteen or 

 twenty huts. 



To the east of the clay pits occurs a circular arrangement of 

 hut-circles, five in number, equidistant from one another. They 

 radiate round a circular cairn of small dimensions, which has a 

 depression in its centre. The lunette position of the five hut- 

 circles is generally to be looked for as a common feature in these 

 villages, but here it is unusually clear, owing to thefurse having 

 been burnt away on Jubilee night, and thus presenting a space 

 bare and open to the eye. 



Further on, a particularly fine hut-circle 38 feet across, with 

 its circular ridge of earth and stones very perfect, is visible. At 

 a little distance lie two more. Not far from these circles some 

 years ago a kist-vaen was found. Its four sides were each 

 formed of a slab of granite, whilst the top and bottom were 

 flagged with two more. It was, of course, destroyed. Within 

 it was a " dome " vessel, which contained some crumbling bones. 

 This has also disappeared. 



The hill has two summits — one on the eastern, and the other 

 on the western side. The western apex was known in Leland's 

 days (1533 — 1552) as Pencair, and now as Castle Pencairn, or 

 Pencair. Above it there is a large gal-gal, on the side of
