At over three metres tall and nearly as wide, the front wall is substantial enough to give the structure a presence that outlasted whatever industry once drove it. When ground in front of it was recently levelled, large quantities of burnt material came to the surface, a reminder that this was once a working place of considerable heat and effort.

Lime kilns were simple but essential structures, typically used to burn limestone at very high temperatures to produce quicklime, which farmers spread on acidic soils to improve fertility, and which builders mixed into mortar. The Racomane example has an unusual trapezoidal plan, narrower at the front at 3.6 metres and widening to 5 metres at the rear, with a total length of 10 metres. That widening towards the back, combined with the way it is built into the hillside, would have helped retain the heat needed to sustain the burn. The central arched recess, standing 1.65 metres high and 2 metres wide, is the opening through which the finished lime would have been raked out. Roughly 40 metres to the north-north-west lies a separate enclosed area, its relationship to the kiln unresolved but suggestive of a broader pattern of activity on this patch of ground.
