Archaeology Notes

NT54NE 3 5574 4842.

Fort, Bonnet Plantation. Situated on a wooded height some 1000' above sea level. In form it has been an irregular oval measuring internally some 220' by 177', enclosed by a rampart of stone, now obliterated; towards the SW there is a trace of a second. The interior has been under cultivation and no entrance is definitely recognisable. (Centred at NT 5571 4845).

RCAHMS 1915, visited 1912

The exact proportions of this earthwork could not be obtained as they are rendered obscure by a dense plantation, but it would seem to be a simple enclosure about 75m diameter, similar to those at Boon (Berwick 20SW 5) and Headshaw (Berwick 13 NE 9) The course of a turf-covered bank 2.5m broad and 0.6m high is traceable on the north segment, and this runs in a southerly direction as a steep scarp 1.2m high until it merges with modern forestry cross-banks. There are still traces of an outer bank on the SW.

Visited by OS (JD) 30 April 1955

NT 5574 4842. The remains of this earthwork, situated in a dense coniferous plantation, are generally as described above, with the exception of the dimensions which are more or less in agreement with those given by RCAHMS. The outer bank, visible on the SW side, is reduced to a scarp.

Surveyed at 1/2500.

Field Visit (April 1912)

222. Fort, Bonnet Plantation, Thirlestane.

This fort (fig. 110) is situated about 1100 yards to the north-west of Thirlestane steading, on a wooded height, at an elevation of about 1000 feet above sea-level. In form it has been an irregular oval, measuring interiorly some 220 feet by 177 feet, enclosed by a rampart of stone now obliterated towards the south-east, and towards the south-west there is a trace of a second. The interior has been under cultivation, and no entrance is definitely recognisable.

Note (14 January 2016 - 31 August 2016)

A heavily reduced enclosure is situated in a coniferous plantation on the crest of a rounded hill NW of Thirlestane. Described as an irregular oval on plan, measuring internally about 67m from NNE to SSW by 54m transversely (0.27ha), its defences had already been heavily reduced before it was first recorded by James Hewat Craw in 1912. The SE sector was missing, and though the rampart was at best a stony bank 2m in thickness by 0.6m in height, on the SW it was accompanied externally by a second. Nothing is visible beneath the trees in the interior and the position of the entrance is unknown. While at face value relatively slight, its hilltop position, size and the presence of other stone-walled forts in the vicinity, argue for it inclusion as a defended site.
