It measures roughly eleven and a half metres north to south and eight metres east to west, rising no more than forty centimetres above the surrounding pasture. What lies beneath and within that modest hump is fire-cracked stone, charcoal, and the accumulated debris of ancient cooking, the calling card of one of Ireland's most widespread and least celebrated prehistoric monument types.

This is a fulacht fia, a term sometimes translated loosely as "cooking place of the deer," though the precise meaning remains debated. The essential idea is straightforward: a trough, usually timber-lined or cut into the ground, was filled with water, and stones heated in a nearby fire were dropped in to bring the water to a boil. Meat could then be cooked without direct flame. The discarded, shattered stones piled up over repeated use into the characteristic horseshoe-shaped or oval mound of burnt material that survives today. Fulachtaí fia are found in their thousands across Ireland, typically dating to the Bronze Age, roughly 2000 to 500 BC, and are almost always located near a water source, whether a stream, a spring, or a boggy hollow. The Lisbane example was recorded and compiled by Denis Power, with the record uploaded in August 2011.

The mound sits in working pasture on a gentle west-facing slope, which means access depends on the landowner's goodwill and the usual courtesies of the Irish countryside. There is nothing monumental to announce its presence from a distance; the site rewards close attention rather than a view from a car window. The slight rise in the grass, darker in colour and uneven in texture where the burnt material lies just below the surface, is the thing to look for. Visiting in late autumn or winter, when grass growth is lower, makes the topographic detail of such a low mound easier to read in the landscape.
