Somewhere in a pasture near the top of a north-west-facing slope in Toor, Co. Waterford, lies an archaeological feature that cannot actually be seen. The site is classified as a burnt mound, a type of prehistoric monument found widely across Ireland and Britain, typically consisting of a spread or mound of heat-shattered, fire-cracked stone, often associated with the repeated heating of water in a trough or pit. They date most commonly to the Bronze Age, and their exact purpose, whether cooking, bathing, industrial processing, or some combination, remains a subject of genuine debate among archaeologists. What makes this particular example quietly curious is that it exists almost entirely as a memory.

Local knowledge records an area of broken and burnt stone roughly fifteen metres in diameter, noticed during land reclamation work. When the site was formally inspected, however, no trace of it was visible at ground level. The mound, if that is still the right word, had effectively been absorbed back into the working landscape, its presence preserved only in the recollections of those who witnessed it being disturbed, and in the formal record that followed. It is a site defined almost entirely by what is no longer there to see.
