It is not a decorative garden feature but a fish-pond, a piscina of the kind that medieval monasteries and priories maintained as a reliable source of fresh fish, particularly important for communities observing the frequent fast days of the liturgical calendar. The fact that local memory has preserved the monastic association across centuries of changed ownership says something about how deeply these features could embed themselves in a place.

The pond is stone-lined and roughly rectangular, measuring approximately thirty metres along its northwest to southeast axis and just over four metres across. A large stone slab covers an overflow outlet at the northwest end, a practical piece of water management that kept the pond at a usable level. What makes the site more than just an isolated curiosity is its possible relationship to a priory located around 550 metres to the west-southwest, and to a clapper bridge, a simple flat-stone crossing laid across a watercourse, that appears to stand in line with the pond to the northwest. A clapper bridge in this alignment hints at a connected series of features, perhaps a processional or working route between the religious house and its food supply. Whether that link is real or coincidental, the physical evidence suggests the pond predates the country house whose grounds now contain it, and that it was originally part of a monastic economy rather than a domestic one.
