This one, a cairn at Knockane in County Kerry, has taken the opposite approach, quietly vanishing from the landscape while remaining stubbornly present on old maps. A cairn is essentially a mound of stones, typically raised over a burial or as a territorial marker, and this one was recorded as a circular feature roughly thirteen metres across on the second edition Ordnance Survey six-inch map of 1916. By the time anyone went to look for it on the ground in 2000, there was nothing to see. The pasture had closed over it entirely.

What makes the site a little more interesting than a simple case of agricultural erasure is the cartographic inconsistency that surrounds it. The place-name attached to this spot on the 1916 map is 'Curravarra', written in ordinary roman script rather than the gothic lettering the Ordnance Survey conventionally used to mark antiquities. That distinction matters: it suggests the surveyors were uncertain whether what they were recording was genuinely ancient. To complicate things further, the first edition six-inch map of 1841 places the same name 'Curravarra' against a separate possible cairn located roughly 500 metres to the west-southwest. Whether the name migrated between editions, or whether it was ever correctly assigned, is not clear. The site sits at the top of an east-southeast-facing slope, about 180 metres north of a linear earthwork known locally as the Red Ditch, a feature that hints at a broader pattern of ancient activity in the area, even if its own origins and purpose remain obscure.
