They are gone now, the monument destroyed, which makes the surviving measurements feel oddly poignant: the north-eastern stone stood roughly 1.9 metres tall, the south-western a more modest 0.9 metres. Together they formed what is classified as a standing stone pair, a type of prehistoric monument found across Ireland in which two upright stones are deliberately set in relation to one another, often along a consistent axis. Here that axis ran ENE to WSW.

The pair was recorded by Condon in 1916, drawing also on earlier observations by Grove-White made sometime between 1905 and 1925. Standing stone pairs are generally understood to date to the Bronze Age, though their precise function remains uncertain; theories range from astronomical or calendrical markers to territorial or ceremonial boundaries. What made this particular pair worth noting was the alignment itself, a detail that field recorders took care to measure and preserve even as the physical stones were already on their way to disappearing from the landscape entirely. The site at Lissard is now known only through those written dimensions and compass bearings, a description of something that can no longer be directly seen.
