But the burnt mound discovered in Dollas Upper, County Limerick, is worth knowing about precisely because of how it came to light and what it tells us about the kind of archaeology that ordinarily stays buried. Burnt mounds are among the most common prehistoric monument types in Ireland, typically consisting of heaps of heat-shattered stone and charcoal left over from repeated episodes of heating water or cooking, often beside a wooden trough. They turn up in their thousands across the island, usually in low-lying, wet ground, and this one fits that pattern almost exactly, sitting in poorly drained, boggy pasture 145 metres southeast of the townland boundary with Dollas Lower.

The site was not found by any deliberate survey. It came to light during topsoil-stripping associated with the Bord Gáis Éireann Pipeline to the West project, as recorded in Grogan et al. (2007). Brian Halpin subsequently excavated it under Licence No. 02E0476, uncovering a shallow oval spread of burnt and fire-cracked angular stones mixed with substantial quantities of charcoal, measuring roughly 11.5 metres east to west and 8 metres north to south. The mound had been sealed beneath peat, and similar peaty deposits were found below it during excavation. Numerous boulders across the site were naturally embedded in a compact yellow-orange subsoil. To the south, an area of stones may have been deliberately arranged as a rough platform surface, built onto a small natural limestone outcrop. No trough or structures were identified, though several shallow pit-like features were present; these were likely natural undulations that had filled with burnt material over time. The only finds were some disarticulated animal bone and teeth.

There is nothing to see at this location today. The monument was fully excavated as part of the pipeline project, and subsequent aerial imagery, including orthophotos from 2005 to 2018, shows no trace of it at the surface. The surrounding land remains rough, boggy pasture, much as it would have been when the mound was in use. For anyone with an interest in how Ireland's prehistoric landscape is documented and lost in almost the same moment, the records held by Brian Halpin's 2004 report offer more than the ground itself ever could at this point.
