When foundations were being dug for a new house beside Limepark House, workers broke into an underground chamber. Those who saw it described it as large, with white-washed walls, a detail that suggests deliberate construction rather than a natural void. Then the building work continued, and the chamber passed back out of sight.

What the space was originally built for is unrecorded. White-washed walls imply a structure that was maintained, or at least finished with some care, which separates it from the rougher stonework of a typical souterrain, an underground passage usually associated with early medieval settlements and used for storage or refuge. Whether it was domestic, agricultural, or something older and harder to categorise, the local account offers no further clues. The site sits near Limepark House, and its precise date and function remain unknown.
