Summary

Cropmarks have revealed a complex enclosure situated on a slight rise in the floor of the valley to the ENE of the confluence of the Billiemire and Auchencrow Burns, which prior to drainage schemes in the early 19th century would have been surrounded by the swamp known as Billie Mire. Topographically, the rise is a spur projecting from slightly higher ground on the ENE and tapers into a rounded point on the WSW. Here there are traces of possibly two ditches enclosing an oval area measuring 55m from ENE to WSW by 45m transversely, and though the cropmarks are faint and diffuse, it is presumably the outer of these that first caught the attention of RCAHMS investigators inspecting vertical aerial photographs in 1950. More recent aerial reconnaissance has recorded a much large enclosure on the spur, its principal feature being two concentric ditches some 3m in breadth and set 7m apart cutting across the neck to bar access from the ENE, and the inner returning along the NW flank to dogleg round the outer ditch of the oval enclosure before disappearing in a damper area of the field. Essentially a triangular promontory enclosure, it measures at least 120m in length from ENE to WSW by a maximum of 110m in breadth (0.6ha), though whether as an annexe to the oval enclosure on the tip or as a free-standing perimeter cannot be demonstrated without excavation. There is at least one entrance facing NE near the N apex of the enclosure, and possibly a second on the E at the S margin of the spur, while a series of diffuse maculae within its interior almost certainly indicate the stances of structures. An outlying ditch extends across the field in a gentle arc from NW to SE about 90m to the NE.
