Summary

This fort is situated on the S shoulder of Thirlestane Hill, where the ground begins to drop away more steeply from the broad rounded summit area. Roughly circular on plan, it was already under young conifers when briefly noted by James Tait in 1883 (1884, 311), and all subsequent records have been drawn up in the face of impenetrable trees or dense undergrowth. The only plan, prepared by James Hewat Craw in 1912 (RCAHMS 1915, 117-18, no.220, fig 108), can therefore only be relied upon in broad outline rather than close detail, depicting three concentric banks forming a circular enclosure, the interior of which appears to have been partly occupied by a series of small yards; Craw placed entrances on the ESE and WSW, though the OS 25 inch maps and satellite imagery suggest these lie closer to the SE and W respectively. Craws profile drawing across the ramparts on the N is informative, however, confirming David Christison and Alexander Curle's observation that the innermost circuit is of comparatively slight proportions, forming a bank about 3m thick and no more than 0.3m high in this sector. It is consistently set about 6.5m within the outer ramparts, enclosing an area some 65m in diameter (0.32ha), and is more likely to represent a later settlement enclosure inserted into the interior of an earlier fort, and the yards recorded within its interior are probably the remains of a still later late Iron Age occupation. The fort as such is thus represented by the two outer circuits, though on the N at least the outer of them was then evidently considerably larger, some 7m thick by 1.8m high externally, while the inner was only 0.6m to 0.9m high there and elsewhere around the entire circuit. Nor is there any evidence of a ditch between them, while Craw's section showing that the outer was rather higher externally than internally is probably evidence that it was accompanied by an external ditch. The evidence that the two outer circuits are part of a contemporary scheme enclosing an area some 82m in diameter (0.52ha) is thus far from certain, and the possibility remains that the outermost rampart represents an earlier fort; indeed, if the outer rampart was the original perimeter, it would have enclosed upwards 0.65ha.
