Drumgreggan Enclosure

Located in a field of flat, damp rush-grown pasture, which is traversed by field drains, in an area of lowlying terrain bordering the S bank of the River Swilly. The steeply rising slope of a NE−SW ridge borders the S side of the field, c. 30m S of the enclosure. Not shown on any edition of the OS 6-inch maps. Visible as a circular feature (diam. 35-38m) in aerial imagery (Digital globe; Google earth) and in Lidar imagery. The imagery suggests the presence of a levelled circular enclosure. In the field a subtle rise is evident, which differs from the rest of the field in that it is largely devoid of field rushes, the grass growth has a slightly richer hue and the ground surface is drier underfoot. However, the full circular outline of an enclosure cannot be confidently traced at ground level. The E side of the area is defined by a slight raised grassy linear feature (Wth c. 2m; L c. 12m NNW−SSE). A field ditch (Wth 2m; D 0.8-1m) on a roughly NE-SW axis cuts across the N edge of the area, probably clipping the enclosure. Notified to NMS by Jean-Charles Caillère.
