What makes them worth pausing over is the suspicion that they were never meant to frame a gateway at all. Classified as a possible standing stone pair, the stones at Mweelin occupy the kind of ambiguous middle ground that prehistoric monuments sometimes inhabit, absorbed into later agricultural landscapes so completely that their original purpose becomes genuinely difficult to untangle.

Standing stone pairs are a recognised monument type in Ireland, generally thought to date to the Bronze Age, though their function remains debated. Some appear to have an astronomical or ceremonial alignment; others may have marked boundaries or significant points in the landscape. At Mweelin, the two stones currently serve as pier stones, the upright pillars on either side of a field gate, which is a very practical second life for large standing stones if that is indeed what they are. The complication is that at least one of the stones is thought to have been moved to its present position at some point, raising the possibility that the pair's original arrangement, and therefore any alignment or spatial relationship they once had, may no longer be intact. The site was brought to wider attention by Helen Riekstiņš, whose observation prompted a closer look at what the field wall had quietly enclosed.
