They left no other obvious trace. What remains is modest in scale but quietly arresting: a handful of cup-and-ring motifs on an irregular, east-facing surface, lightly crusted with lichen and easy to walk past without noticing.

Cupmarks are exactly what they sound like, small hemispherical depressions pecked into rock, and cup-and-rings add one or more concentric circular grooves around that central hollow. They appear across Atlantic Europe and are generally associated with the Neolithic and Bronze Age periods, though their purpose remains genuinely unresolved. The Kealduff outcrop, measuring roughly four metres north to south and two metres east to west and narrowing toward the north-east, carries three such motifs clustered on its surface. The largest cup-and-ring has a cupmark four centimetres across encircled by a ring ten centimetres in diameter, positioned roughly midway along the outcrop and sixty-five centimetres in from the western edge. About twenty centimetres to its south-west sits a plain cupmark of the same diameter. Forty-five centimetres to the north-east is the third motif, a slightly smaller cup-and-ring with a three-centimetre cupmark and a seven-centimetre ring. The spacing and sizing give the grouping an almost considered quality, though whether that reflects ritual intention, practical geometry, or something else entirely is not something the rock itself will answer.
