A circular earthwork sits in the landscape, and within its circumference there appear to be the remnants of wall footings, the ghost of a building that once occupied the interior. It is the kind of feature that only really declares itself from above, its geometry legible in the crop and grass patterns that accumulate over buried or degraded structures across centuries of undisturbed soil.

The earthwork lies roughly 140 metres west of a ringfort, a type of enclosed settlement that was common across Ireland during the early medieval period, typically consisting of a circular bank and ditch enclosing a domestic space. Whether the Cummerstown earthwork shares a relationship with that neighbouring ringfort, whether contemporary with it or of a different era altogether, is not established. What the aerial photograph taken in December 2004 does show is a circular form with what may be structural remains inside, a combination that suggests purposeful enclosure rather than a purely natural feature. The proximity to Lough Adeel places it within a broader landscape that clearly sustained settlement and activity over a long period, though the specific function and date of this particular earthwork remain open questions.
