They are easy to overlook, grass-covered spreads of dark, fire-cracked stone that barely interrupt the surface of the land. Yet together they represent something quietly telling about how this particular patch of ground was used, repeatedly, across prehistoric time.

A fulacht fia, sometimes called a burnt mound, is the accumulated debris from a cooking method that relied on heating stones in a fire and then dropping them into a water-filled trough to bring the contents to a boil. The stones crack and fragment with the repeated heating and cooling, and over time the discarded material builds up into the characteristic horseshoe-shaped or spread mounds that survive today. They are among the most common prehistoric monuments in Ireland, typically dating to the Bronze Age, though some sites were in use earlier or later. The Mashanaglass example recorded here measures six metres in length and four metres in width, a modest but intact-looking spread of burnt material still holding its shape beneath the grass. The proximity of a second fulacht fia just ten metres to the west raises questions that the surviving evidence alone cannot answer: whether the two were used at the same time, by the same community, or represent entirely separate episodes of activity separated by generations.
