It is not a stone circle. What the cartographers recorded with such antiquarian flourish was, in all likelihood, a lime kiln, a working industrial structure used to burn limestone and produce quicklime for spreading on fields or for use in mortar. The misidentification is a small, telling reminder of how readily a functional object can acquire an air of mystery when its purpose is no longer obvious to the person drawing the map.

The structure itself sits on a south-east-facing slope in an undulating landscape, and its form is consistent with a type of kiln built into a hillside rather than freestanding. An overgrown pit, roughly 5.2 metres along its north-east to south-west axis and 3.2 metres across, has been cut into the slope and left open to the south-east. The retained earth and material behind it is held in place by a stone-facing wall that still stands to a maximum height of 1.75 metres. Building a kiln into a hillside was a practical choice: the slope allowed fuel and limestone to be loaded from above while the drawn air from the open face below helped sustain the burn. The vegetation that has since grown over it is part of what made the 1907 surveyor pause and reach for the gothic script.
