Summary

This fort exploits the steep-sided promontory forming the E side of the mouth of the deeply incised gully where the Bilsdean Burn cuts through the coastal escarpment. Triangular on plan, the cliif-top is cut off by a massive earthen rampart up to 10m in thickness by 3.5m in height, enclosing an area measuring 70m from ESE to WNW by about 50m transversely (0.37ha). In addition to the broad gap in the southern arc, on the NE the rampart terminates short of the cliff-edge, but in both sectors it is depicted as a continuous arc on the 1st edition OS 6-inch map (Haddingtonshire 1854, sheet 12). The map also shows a concentric hedge-line some 10m outside it, almost certainly indicating the position of an external ditch. By 1893, the perimeter had been reduced to its present state, but the first 25-inch depiction (Haddingtonshire 1894, sheet 13.5) shows a separate short length of rampart extending into the field on the E of the gully a further 70m to the SW; the purpose and extent of this equally massive bank are uncertain, but in 1913 it led RCAHMS investigators into believing that it and the main rampart had formed a continuous barrier to cut off an area of 0.6ha; all later investigators have adopted this view (Hogg 1945; OS 1:2500 revision 1966). While the map evidence indicates that this is not the case, this second rampart lies so far out from the inner perimeter that it is quite likely to represent a separate line of defence of a much bigger enclosure of at least 0.6ha in extent. In 1853 the OS surveyors noted that cists had been discovered here some years before (Name Book, Haddingtonshire) No.16, pp 21, 63), while in 1913 RCAHMS noted that 'stone foundations had been ploughed up within the interior (RCAHMS 1924, 79, no.126); a fragment of Roman glass has also been discovered in the interior (Hogg 1945).

Investigation History

Depicted on Roy's map 1747-55, it also appears in more detail on the 1st edition of the OS 6-inch map (Haddingtonshire 1854, sheet 12) and the 25-inch map (Haddingtonshire 1894, sheet 13.5), which chart the partial demolition of the main rampart. Visited in 1913 by J G Callander for RCAHMS, a description appears in the County Inventory for East Lothian (RCAHMS 1924, 79, no.126). The OS revised the 1:2500 depiction in 1966.
