Borlase, in his _History of Cornwall_ (1769), only mentions the circle, but W. C. Borlase, in his _Nænia Cornubiæ_ (1872), gives a very rough plan including the stones before mentioned and several barrows, some of which have been ploughed up. At varying distances from the circle and in widely different azimuths are other standing stones, ancient crosses and holed stones, while some of the barrows can still be traced. The descriptions of the locality given by Borlase and Lukis, however, do not exhaust the points of interest. Edmonds[112] writes as follows:-- “A cave still perfect... is on an eminence in the tenement of Boleit (Boleigh) in St. Buryan, and about a furlong south-west of the village of Trewoofe (Trove). It is called the ‘Fowgow,’ and consists of a trench 6 feet deep and 36 long, faced on each side with unhewn and uncemented stones, across which, to serve as a roof, long stone posts or slabs are laid covered with thick turf, planted with furze. The breadth of the cave is about 5 feet. On its north-west side, near the south-west end, a narrow passage leads into a branch cave of considerable extent, constructed in the same manner. At the south-west end is an entrance by a descending path; but this, as well as the cave itself, is so well concealed by the furze that the whole looks like an ordinary furze break without any way into it. The direction of the line of this cave is about north-east and south-west, which line, if continued towards the south-west, would pass close to the two ancient pillars called the Pipers, and the Druidical temple of Dawns Myin, all within half of a mile.” This fougou is situated on a hill on the other side of the Lamorna Valley, near the village of Castallack, and the site of the Roundago shown in the 1-inch Ordnance map. Borlase[113] says that many similar caves were to be seen “in these parts” in his time, and others had been destroyed by converting the stones to other uses.
